TECHNICAL FIELD

The present disclosure is in the field of bioactive compositions having pesticidal activity and methods for their use in controlling plant pests. In particular, such

compositions comprise a Bacillus strain and/or its metabolites, more particularly strains of Bacillus megaterium and their metabolites. BACKGROUND

Natural products are substances produced by microbes, plants, and other organisms. Microbial natural products offer an abundant source of chemical diversity, and there is a long history of utilizing natural products for pharmaceutical purposes. Despite the emphasis on natural products for human therapeutics, where more than 50% are derived from natural products, only 11% of pesticides are derived from natural sources.

Nevertheless, natural product pesticides have a potential to play an important role in controlling pests in both conventional and organic farms. Secondary metabolites produced by microbes (bacteria, actinomycetes and fungi) provide novel chemical compounds which can be used either alone or in combination with known compounds to effectively control insect pests and to reduce the risk for resistance development. There are several well- known examples of microbial natural products that are successful as agricultural insecticides (Thompson et al., 2000; Arena et al., 1995; Krieg et al. 1983).

The development of a microbial pesticide starts with the isolation of a microbe in a pure culture. It then proceeds with efficacy and spectrum screening using in vitro, in vivo or pilot scale trials in a greenhouse and in the field. At the same time, active compounds produced by the microbe are isolated and identified. For the commercialization of a microbial pesticide, the microbe has to be economically produced by fermentation at an industrial scale, and formulated with a biocompatible carrier and approved additives to increase efficacy and to maximize the ease of application. Uses of Bacillus Megaterium and Products Produced Therefrom

Bacillus megaterium is a Gram-positive bacterium that grows in simple media and on more than 62 out of 95 carbon sources, such as tricarboxylic acid cycle intermediates {e.g. , formate and acetate), and forms spores mainly under aerobic conditions (see, for example, Vary, 2007), It has been found in a variety of habitats, such as soil, seawater, sediment, rice paddies, honey, fish, and dried food.

Bacillus megaterium has been found to have a number of different uses.

Specifically, it produces a variety of industrial enzymes such as penicillin acylase, various amylases, and glucose dehydrogenase (reviewed in, Vary, 2007). Additionally, a fermentation of B. megaterium ATCC 19213 grown to stationary phase was found to produce N-Deoxyschizokinen, a siderophore, which was identified as 4- [(3(acetylhydroxyamino) propyl) amino]-2-[2-[(3-(acetylamino) propyl) amino]-2- oxoethyl]-2-hydroxy-4-oxo-butanoic acid (Hu X and Boyer G. L, 1995). Schizokinen, a citrate-containing dihydroxamate, a siderophore has been produced by B. megaterium and Anabaena sp (Plowman J. E. et al 1984). The involvement of the citrate - hydroxycarboxylate moiety in iron chelation was investigated by comparing the iron binding behavior of schizokinen with that of acetylschizokinen, a derivative in which the citrate hydroxyl group was modified by acetylation.

Another set of uses for products derived from Bacillus megaterium has been medicinal uses. BMG 59-R2, a peptide antibiotic, has been reported from B. megaterium (FERM-p 6177). The compound also inhibits alkaline phosphatase and tumour growth (Japan. Pat, 83 164 561. (1983)). Fermentation culture of B. megaterium in the presence of ansatrienin produces T23V and T23VI (Damberg, M. et al 1982). These compounds belong to the class of macrolides antibiotics, which also exhibit antitumor activity. A nucleoside named oxetanocin was isolated from B. megaterium ΝΚ84-0218 and the structure was determined to be 9-[(2R,3R,4S)-3,4-bis(hydroxymethyl)-2-oxetanyl]adenine by X-ray crystallographic analysis (Shimada Ν. et a., 1986). Oxetanocin showed activity against herpes simplex virus-II (DNA virus) at 5.8 pg/well (50% inhibition of cytopathic effect), while the cytotoxicity against Vero cells was 132.6 g/well (50% inhibition of cell growth). Later, the derivatives of oxetanocin such as oxetanocins H, X, G and 2- aminooxetanocin A (Shimada N. et a., 1987) are isolated from the same strain which showed antiviral activities against herpes simplex virus type-II (HSV-II) and antiviral activities against human immunodeficiency virus. B. megaterium IFO 12108 (Nakahama, K. et al., 1981) was used for the microbial transformation of anamtiocin, an antitumor antibiotic produced by Nocardia sp. C-15003 (N-l). Ansamitocin P-3 was converted into 15-hydroxyansamitocin P-3 (PHO-3), and 15-epi-15-hydroxyansamitocin P-3 (epi-PHO-3), by using B. megaterium (Izawa M. et al., 1981). The microbial conversion product of P-3, has greater antitumor activities against P 388 and L 1210 than the substrate P-3.

Various isolates of Bacillus megaterium have been used as insecticides, bactericides, fungicides and nematicides (see, for example, Aksoy, H.M. 2008; US Patent Nos.

6,599,503, 7,906,131, 7,935,360). Some of these B. megaterium isolates have been used in combination with other bacteria to treat sludge and wastes such as Artemisia annua residue, flue dust, bran powder, feces of livestock and poultry, peat, and crop straw (see, for example, US Patent No. 7,279,104).

"Percent Identity" means the value determined by comparing two optimally aligned sequences over a comparison window, wherein the portion of the polynucleotide sequence in the comparison window may comprise additions or deletions (i.e., gaps) as compared to the reference sequence (which does not comprise additions or deletions) for optimal alignment of the two sequences. The percentage is calculated by determining the number of positions at which the identical nucleic acid base occurs in both sequences to yield the number of matched positions, dividing the number of matched positions by the total number of positions in the window of comparison, and multiplying the result by 100 to yield the percentage of sequence identity.

Optimal alignment of sequences for comparison can use any means to analyze sequence identity (homology) known in the art, e.g., by the progressive alignment method of termed "PILEUP" (Morrison, 1997), as an example of the use of PILEUP); by the local homology algorithm of Smith & Waterman, (1981); by the homology alignment algorithm of Needleman & Wunsch (1970); by the search for similarity method of Pearson (1988); by computerized implementations of these algorithms (e.g., GAP, BEST FIT, FASTA, and TFASTA in the Wisconsin Genetics Software Package, Genetics Computer Group, 575 Science Dr., Madison, Wis.); ClustalW (CLUSTAL in the PC/Gene program by

Intelligenetics, Mountain View, Calif., described by, e.g., Higgins (1988); Corpet (1988); Huang (1992); and Pearson (1994); Pfamand Sonnhammer (1998); Tree Align (Hein (1994); MEG- ALIGN, and SAM sequence alignment computer programs; or, by manual visual inspection.

Another example of an algorithm that is suitable for determining sequence similarity is the BLAST algorithm, which is described in Altschul et al., (1990). The BLAST programs (Basic Local Alignment Search Tool) of Altschul, S. F., et al., (1993) searches under default parameters for identity to sequences contained in the BLAST "GENEMBL" database. A sequence can be analyzed for identity to all publicly available DNA sequences contained in the GENEMBL database using the BLASTN algorithm under the default parameters. Software for performing BLAST analyses is publicly available through the National Center for Biotechnology Information, www.ncbi.nlm.nih.gov/; see also Zhang (1997) for the "PowerBLAST" variation. This algorithm involves first identifying high scoring sequence pairs (HSPs) by identifying short words of length W in the query sequence that either match or satisfy some positive valued threshold score T when aligned with a word of the same length in a database sequence. T is referred to as the neighborhood word score threshold (Altschul et al., (1990)). These initial neighborhood word hits act as seeds for initiating searches to find longer HSPs containing them. The word hits are extended in both directions along each sequence for as far as the cumulative alignment score can be increased. Extension of the word hits in each direction are halted when: the cumulative alignment score falls off by the quantity X from its maximum achieved value; the cumulative score goes to zero or below, due to the accumulation of one or more negative- scoring residue alignments; or the end of either sequence is reached. The BLAST algorithm parameters W, T and X determine the sensitivity and speed of the alignment. The BLAST program uses as defaults a wordlength (W) of 11 , the BLOSUM62 scoring matrix (see

Henikoff (1992)) alignments (B) of 50, expectation (E) of 10, M=5, N=-4, and a comparison of both strands. The term BLAST refers to the BLAST algorithm which performs a statistical analysis of the similarity between two sequences; see, e.g., Karlin (1993). Methods of Production

As noted above, compounds or metabolites may be obtained, are obtainable or are derived from an organism having the identifying characteristics of a B. megaterium, or alternatively from any other microorganism. The methods comprise growing these organisms (e.g. , in culture) and obtaining the compounds and/or compositions of the present invention by isolating these compounds from the culture of these organisms.

In particular, the organisms are cultivated in nutrient medium using methods known in the art. The organisms may be cultivated by shake flask cultivation, small scale or large scale fermentation (including but not limited to continuous, batch, fed-batch, or solid state fermentations) in laboratory or industrial fermentors performed in suitable medium and under conditions allowing cell growth. The cultivation may take place in suitable nutrient medium comprising carbon and nitrogen sources and inorganic salts, using procedures known in the art. Suitable media are available from commercial sources or can be prepared according to published compositions. After cultivation, a supernatant, filtrate and/or extract of or derived from B.

megaterium may be used in formulating a pesticidal composition.

Alternatively, after cultivation, the compounds and/or metabolites may be extracted from the culture broth.

The extract may be fractionated by chromatography. Chromatographic fractions may be assayed for toxic activity against, for example, free-living nematodes and plant parasitic nematodes, M. incognita and/or M. hapla using methods known in the art. This process may be repeated one or more times using the same or different chromatographic methods.

Application of an effective pesticidal control amount of a supernatant, filtrate or extract containing a pesticidally active metabolite, or isolated compound produced by the B. megaterium or application of combinations of the foregoing is provided. The strain or supernatant or filtrate or extract, metabolite and/or compound is applied, alone or in combination with another pesticidal substance, in an effective pest control or pesticidal amount. An effective amount is defined as that quantity of microorganism cells, supernatant, filtrate or extract, metabolite and/or compound alone or in combination with another pesticidal substance that is sufficient to modulate pest infestation. The effective rate can be affected by pest species present, stage of pest growth, pest population density, and environmental factors such as temperature, wind velocity, rain, time of day and seasonality. The amount that will be within an effective range in a particular instance can be determined by laboratory or field tests. Plant Growth Promotion

The compositions disclosed herein, in particular, Bacillus megaterium and/or a supernatant, filtrate, extract, compound, metabolite or cell fraction obtained from a culture of B. megaterium, can be used to modulate or more particularly promote growth of plants, e.g. crops such as fruit (e.g. , strawberry), vegetable (e.g. , tomato, squash, pepper, eggplant), or grain crops (e.g. , soy, wheat, rice, corn), tree, flower, ornamental plants, shrubs (e.g. , cotton, roses), bulb plant (e.g. , onion, garlic) or vine (e.g. , grape vine). The compositions can also be used to modulate the germination of a seed(s) in a plant(s).

The compositions disclosed herein, or formulated product, can be used alone or in combination with one or more other components as described below, such as growth promoting agents and/or anti-phytopathogenic agents in a tank mix or in a program

(sequential application called rotation) with predetermined order and application interval during the growing season. When used in a combination with the above-mentioned products, at a concentration lower than recommended on the product label, the combined efficacy of the two or more products (one of which is the said composition disclosed herein) is, in certain embodiments, greater than the sum of each individual component's effect. Hence, the effect is enhanced by synergism between these two (or more) products, and the risk for the development of pesticide resistance among the plant pathogenic strains is reduced.

The composition can be applied by root dip at transplanting, specifically by treating a fruit or vegetable with the composition by dipping roots of the fruit or vegetable in a suspension of said composition (about 0.25 to about 1.5 % and more particularly about 0.5% to about 1.0% by volume) prior to transplanting the fruit or vegetable into the soil.

Alternatively, the composition can be applied by drip or other irrigation system. Specifically, the composition can be injected into a drip irrigation system. In a particular embodiment, the composition is applied at a concentration of lxlO ⁸ CFU/ml in a volume of approximately 11 to approximately 4 quarts per acre.

In yet another embodiment, the composition can be added as an in-furrow application. Specifically, the composition can be added as an in-furrow spray at planting using nozzles calibrated to deliver a total output of 2-6 gallons/acre. Nozzles are placed in the furrow opener on the planter so that the pesticide application and seed drop into the furrow are simultaneous.

Mixtures of the disclosed compositions with, for example, a solid or liquid adjuvant are prepared in known manner. For example, mixtures can be prepared by homogeneously mixing and/or grinding the active ingredients with extenders such as solvents, solid carriers and, where appropriate, surface-active compounds (surfactants). The compositions can also contain additional ingredients such as stabilizers, viscosity regulators, binders, adjuvants as well as fertilizers or other active ingredients in order to obtain special effects.

Combinations with Plant Growth Promoting Agents

The compositions disclosed herein can be used in combination with other growth promoting agents such as synthetic or organic fertilizers (e.g. , di-ammonium phosphate, in either granular or liquid form), compost teas, seaweed extracts, plant growth hormones such as IAA (indole acetic acid) used in a rooting hormone treatment for transplants either alone or in combination with plant growth regulators such as IBA (indole butyric acid) and NAA (naphthalene acetic acid), and growth promoting microbes, such as, for example, Bacillus spp., Pseudomonads, Rhizobia, and Trichoderma. Seed Treatments

Seed treatments include application of a pesticidal composition, optionally in combination with other bioactive, antagonistic or symbiotic agents to the surface of a seed prior to sowing. Pesticidal toxins, proteins, and/or compounds disclosed herein can be applied to seeds as dry powders, slurried powders or sprayed on the seed before planting.

The compositions disclosed hereion can be formulated for seed treatments in any of the following modes: dry powder, water slurriable powder, liquid solution, flowable concentrate or emulsion, emulsion, microcapsules, gel, or water dispersible granules.

In the case of a dry powder, the active ingredient is formulated similarly to a wettable powder, but with the addition of a sticking agent, such as mineral oil, instead of a wetting agent. For example, one kg of purified talc powder (sterilized for 12 h), 15 g calcium carbonate, and 10 g carboxymethyl cellulose are mixed under aseptic conditions following the method described by Nandakumar et al (2001). Active ingredient(s) is/are mixed in a 1 :2.5 ratio (suspension to dry mix) and the product is shade dried to reduce moisture content to 20-35%.

The compositions disclosed herein can also be used in combination with seed- coating agents. Such seed coating agents include, but are not limited to, ethylene glycol, polyethylene glycol, chitosan, carboxymethyl chitosan, peat moss, resins and waxes or chemical fungicides or bactericides with either single site, multisite or unknown mode of action. In additional embodiments, the disclosed compositions can be applied to seeds by seed imbibition or as a powdered inoculum.

Anti-Phytopathogenic agents

The compositions disclosed herein can also be used in combination with other anti- phytopathogenic agents, such as plant extracts, biopesticides, inorganic crop protectants (such as copper), surfactants (such as rhamnolipids; Gandhi et al., 2007) or natural oils such as paraffinic oil and tea tree oil possessing pesticidal properties or chemical fungicides or bactericides with either single site, multisite or unknown mode of action. As defined herein, an "anti-phytopathogenic agent" is an agent that modulates the growth of a plant pathogen, particularly a pathogen causing soil-borne disease on a plant, or alternatively prevents infection of a plant by a plant pathogen. A plant pathogen includes but is not limited to a fungus, bacteria, actinomycete or virus.

As noted above, the anti-phytopathogenic agent can be a single-site anti-fungal agent which can include but is not limited to benzimidazole, a demethylation inhibitor

(DMI) (e.g., imidazole, piperazine, pyrimidine, triazole), morpholine, hydroxypyrimidine, anilinopyrimidine, phosphorothiolate, quinone outside inhibitor, quinoline, dicarboximide, carboximide, phenylamide, anilinopyrimidine, phenylpyrrole, aromatic hydrocarbon, cinnamic acid, hydroxyanilide, antibiotic, polyoxin, acylamine, phthalimide, benzenoid (xylylalanine). In a more particular embodiment, the antifungal agent is a demethylation inhibitor selected from the group consisting of imidazole, piperazine, pyrimidine and triazole (e.g. , bitertanol, myclobutanil, penconazole, propiconazole, triadimefon, bromuconazole, cyproconazole, diniconazole, fenbuconazole, hexaconazole, tebuconazole, tetraconazole). In a most particular embodiment, the antifungal agent is myclobutanil. In yet another particular embodiment, the antifungal agent is a quinone outside inhibitor (e.g. , strobilurin). The strobilurin may include but is not limited to azoxystrobin, kresoxim- methyl or trifloxystrobin. In yet another particular embodiment, the anti-fungal agent is a quinone, e.g., quinoxyfen (5,7-dichloro-4-quinolyl 4-fluorophenyl ether).

In yet a further embodiment, the fungicide is a multi-site non-inorganic, chemical fungicide selected from the group consisting of chloronitrile, quinoxaline, sulphamide, phosphonate, phosphite, dithiocarbamate, chloralkythios, phenylpyridine-amine, and cyano- acetamide oxime.

In yet a further embodiment, the anti-phytopathogenic agent can be streptomycin, tetracycline, oxytetracycline, copper, or kasugamycin. EXAMPLES

The composition and methods set forth above will be further illustrated in the following, non-limiting Examples. The examples are illustrative of various embodiments only and do not limit the claimed invention regarding the materials, conditions, weight ratios, process parameters and the like recited herein.

Example 1: Isolation and identification of the microbes

Bacillus megaterium strain H491 was isolated from soil collected in Kwadaso, Ghana, Africa. Bacillus megaterium strains MO 18 and J 142 were recovered from soils collected in California. The bacteria were recovered from the sample by traditional plate dilution methods as described by Lorch et al., 1995. Briefly, the sample was resuspended in sterile deionized water. Serial dilutions of the resuspended sample were prepared in sterile water. Some of these dilutions were spread onto agar plates (for example Potato Dextrose Agar) and incubated in the dark and at room temperature. After several days of incubation, colonies were recovered from the surface of the agar plate.

The isolates grew as dense, flat, cream colored colonies. The isolated bacteria are gram-positive. Example 2: Identification of Bacillus megaterium strain H491, strain J142, and strain M018 by sequencing of rRNA and recA genes

The isolates (H491 , J 142 and M018) were identified as a Bacillus megaterium through 16s rRNA amplification and additional sequencing of the recA gene using universal bacterial primers (Cerritos et al., 2008).

Growth from a 24 hour potato dextrose plate was scraped with a sterile loop and resuspended in DNA extraction buffer. DNA was extracted using the MoBio Ultra Clean Microbial DNA extraction kit. DNA extract was checked for quality/quantity by electrophoresis of a 5uL aliquot on a 1 % agarose gel.

rRNA sequences

PCR reactions for the amplification of the 16S rRNA gene were set up by combining

2 mL of the clean DNA extract with 25 mL of GoTaq Green Mastermix, 1.5 mL forward primer (27F primer; 5 ' - AGAGTTTGATCMTGGCTC AG-3 ' (SEQ ID NO: 10)), 1.5 mL reverse primer (1525R primer; 5'- AAGGAGGTGWTCCARCC -3' (SEQ ID NO: l l)). The reaction volume was made up to 50 mL using sterile nuclease-free water. The PCR reaction was conducted on a thermocycler machine under the following conditions: 10 minutes at 95°C (initial denaturing), 30 cycles of 45 seconds at 94°C, 45 seconds at 55°C and 2 minutes at 72°C, followed by 5 minutes at 72°C (final extension) and a final hold temperature of 10°C.

The size, quality and quantity of the PCR product was evaluated by electrophoresis of a 5uL aliquot on a 1 % agarose gel, and comparison of the product band to a mass ladder.

Excess primers, nucleotides, enzyme and template were removed from the PCR product using the MoBio PCR clean up Kit. The cleaned PCR product was subjected to direct sequencing using the primers described above.

The forward (27F, SEQ ID NO: 1) and reverse sequences (1525R, SEQ ID NO:2) were aligned using the BioEdit software, and a 1451 bp consensus sequence was created (see SEQ ID NO:3, infra). The 16S rRNA gene consensus sequence of strain H491 was compared to available representative bacterial 16S sequences using BLAST. For strain H491, the closest match was to Bacillus megaterium (GenBank accession number

CP001983.1), with 99% similarity.

PCR reactions for the amplification of the recA gene were set up by combining 2 uL of the clean DNA extract with 25 uL of GoTaq Green Mastermix, 1.5 forward primer (recAf, 5'- GATCGTCARGCAGSCYTWGAT -3' , SEQ ID NO: 12), and 1.5 μΐ. reverse primer (recAr, 5'- TTWCCRACCATAACSCCRAC -3', SEQ ID NO: 13). The reaction volume was brought up to 50 using sterile nuclease-free water. The PCR reaction was conducted on a thermocycler machine under the following conditions: 5 minutes at 95°C (initial denaturing), 30 cycles of 30 seconds at 95°C, 30 seconds at 45°C and 1 minute at 72°C, followed by 5 minutes at 72°C (final extension) and a final hold temperature of 4 °C.

The size, quality and quantity of the PCR product was evaluated by running a 5μΕ aliquot on a 1 % agarose gel, and comparing the product band to a mass ladder. Excess primers, nucleotides, enzyme and template were removed from the PCR product using the MoBio PCR clean up Kit. The cleaned PCR product was subjected to direct sequencing using the primers described above.

The forward and reverse sequences were aligned using the BioEdit software, and a 505 bp consensus sequence was created.

The recA gene consensus sequence of each strain (H491 , J 142 and MO 18) was compared to representative bacterial sequences using BLAST. The closest species match was to the complete genome of Bacillus megaterium (accession number CPOOl 982.1) with 99% similarity.

All isolates were 99-100% match to Bacillus megaterium DSM319, as well as other strains of Bacillus megaterium. These results confirm the identity of the three isolates as Bacillus megaterium.

Example 3: Biochemical characterization of B. megaterium H491

Bacillus megaterium strain H491 was determined to be gram positive, urease positive, catalase positive, oxidase negative and lipase positive. Extensive biochemical characterization of the isolate was performed using Biolog Phenotypic Microarrays. The full Biolog Phenotypic microarray consists of twenty 96-well plates, each well containing a different carbon, nitrogen, phosphorus or other nutrient source. Some of the plates also contain different antibiotics, metals, etc., to evaluate susceptibility of the isolate.

Absorbance readings from the wells in each plate were compared to a negative control well. Absorbance readings above the negative control threshold indicated growth of the isolate under the conditions in a particular well, while reading at or below the negative control indicated that the isolate failed to thrive under the specific conditions of that well. The test was performed for H491 at 25°C, with duplicate plates for each phenotype test.

B.megaterium strain H491 was able to utilize the following carbohydrates, organic acids and peptides as carbon sources: L- Arabinose, N-Acetyl-D-Glucosamine, D-Galactose, L-Aspartic acid, L-Proline, D-Trehalose, Dulcitol, Glycerol, D-Glucuronic acid, D- Gluconic acid, D-Xylose, L-Lactic acid, D-Mannitol, L-Glutamic acid, D-Glucose-6- Phosphate, D-Galactonic acid-g-Lactone, D,L-Malic acid, D-Ribose, D-Fructose, a-D- Glucose, Maltose, D-Melibiose, Thymidine, L-Asparagine, D-Aspartic acid, a-Ketoglutaric acid, Sucrose, L-Glutamine, Maltotriose, Citric acid, Fumaric acid, Bromosuccinic acid, L- Alanine, Ala-Gly, Methylpyruvate, L-Malic acid, L-Lyxose, Pyruvic acid, Dextrin, Glycogen, D-Arabinose, Arbutin, 2-Deoxy -D-Ribose, 3-O-b-D-Galactopyranosyl-D-

H491 was able to utilize the following amino acids as nitrogen sources:

L-Glutamine, L-Pyroglutamic acid, L-Glutamic acid, L-Asparagine, L-Ornithine, D- Asparagine, L-Proline, L-Aspartic acid, D-Alanine, L-Arginine, L-Alanine, L-Serine, D- Aspartic acid, L-Tryptophan, and L-Tyrosine. It was also able to utilize Urea, Putrescine, Agmatine, N-Acetyl-D-Glucosamine, Cytidine, Guanosine, Inosine, Xanthine, Uric acid, Allantoin, g-Amino-N-Butyric acid and a-Amino-N-Valeric acid as additional organic nitrogen sources. H491 could also utilize ammonia, nitrite and nitrate as inorganic nitrogen sources.

H491 was able to utilize a variety of substrates as phosphorous sources, including Phosphate, Thiophosphate, Dithiophosphate, D-Glucosamine-6-Phosphate, Cysteamine-S- Phosphate, Uridine 2\3"-Cyclic Monophosphate, and Thymidine 5" -Monophosphate.

Metabolism of H491 was inhibited below pH 5, but restored at pH 4.5 in the presence of L-arginine, L-methionine and 5-hydroxy-lysine. Growth was observed between pH 5 to pH 10. The strain did not tolerate NaCl above 5%, and only slight growth was detected at 4% NaCl. The Bergey's Manual of Systematic Bacteriology indicates that Bacillus megaterium isolates can use citrate as a sole carbon source; most can grow at 7% NaCl, but none at 10% NaCl; and most strain do not reduce nitrate. In contrast, H491 did not tolerate NaCl above 5%, and was able to utilize both nitrate and nitrite as nitrogen sources. Example 4: Production of B. megaterium H491, M018 and J142 by fermentation

A supernatant with nematicidal activity was produced through the submerged fermentation of strain H491 under aerobic conditions in liquid V8 medium. Other suitable media include tryptic soy broth, or any nutrient medium containing appropriate carbon and nitrogen sources.

A seed plate was started by streaking a fresh potato dextrose agar plate with a small amount of strain H491, using a sterile loop. The plate was incubated at 25°C for 2-3 days or until enough biomass was evident on the surface of the plate. A 50 mL V8 medium seed flask was inoculated with one loopful of material collected from the agar plate surface. The seed was incubated in a shaker at 200 rpm for 2 days.

A glass 2.8 L, non-baffled fernbach flask containing 500 mL of V8 medium was aseptically inoculated with 2 % of seed. The fermentation was allowed to proceed at 25 °C for 5 days with constant agitation at 150-200 rpm.

The supernatant was obtained by separation the cells from the spent fermentation broth by centrifugation, or other means of separation. Activity of the supernatant was verified by means of the bioassay described below.

megaterium

Similarity indices of the FAME profiles to the database were all within the species confidence threshold (0.948-0.991). A dendogram was built by cluster analysis techniques to produce unweighted pair matching based on fatty acid compositions. The results indicate that H491 (listed as MBI-303) is most similar to J142, and that M018 is more different from the other two strains. Example7: MALDI-TOF identification of isolates H491, M018 and J142

Samples were submitted for MALDI-TOF (Matrix Assisted Laser

Desorption/Ionization-Time of Flight) spectrometry profiling and identification to MIDI Labs, Inc (Newark, DE)to create a profile from the ribosomal proteins of the isolates. The profile was compared to a proprietary database, and the isolates were identified based on their MALDI-TOF scores. MALDI-TOF scores above 2.000 provide identification confidence to the species level, scores from 1.700-1.999 to the genus level, and scores below 1.700 indicate no match in the database. Both H491 and M018 yielded MALDI-TOF scores above 2.000 ( 2.163 and 2.291 respectively), while J142 had a score of 1.972. These results indicate that the ribosomal protein profile of J142 may be unique within the Bacillus megaterium species.

Example 8: Efficacy of Bacillus megaterium isolates against Root-knot Nematodes

(Meloidogyne incognita)-Agar Assays A: Water- Agar- Assay#l

To determine and compare the effects of different Bacillus megaterium strains on root-knot nematodes (Meloidogyne incognita VW6), a water-agar-assay was conducted. Seven-day -old 'White Wonder' cucumber seedlings were transferred on water agar in 60- mm-diameter petri dishes at a rate of one seeding/plate. Cucumbers were then treated with 300 ml of B. megaterium H491 fermentation supernatant and 700 M. incognita/plate, with six replications of each treatment. After incubation for 11 days, the number of galls in cucumber roots was recorded. The results, shown in Table 3, indicate that all strains significantly reduced the number of galls in cucumber roots compared with the water control.

To assess the effect of the top supernatant of B. megaterium H491 on juveniles (J2s) of root-knot nematodes {Meloidogyne incognita VW6), the following test was conducted on 60 mm-diameter petri dishes:

Seeds of cucumber cv. 'White Wonder' were germinated on wet tissue paper in petri dishes at room temperature. A week later, germinated seedlings were transferred to water agar in petri dishes at the rate of one seedling/dish. A 300-ml aliquot of B. megaterium. H491 fermentation supernatant was added into each dish, after which 300 M. incognita J2s were added in 150 ml of deionized water. Petri dishes were then covered and incubated at 25°C for 7 days. Water, media blank and Avid (0.1 %) were used as negative, negative, and positive controls, respectively. The effect of each substance on nematode survival was assessed after 7 days by counting the number of galls in cucumber roots, and expressed as a percentage of the water control. Experiments were conducted in duplicate.

The results, presented in Figure 9, show that B. megaterium H491 supernatant significantly reduced the number of galls in cucumber roots compared with the water control in both trials, which indicated that H491 was effective against M. incognita and can be used for management of this nematode in cucumber. Example 9: In vitro Assays With M. incognita and M. hapla

A: In vitro nematicidal bioassay against M. incognita and M. hapla

In order to ensure consistent and adequate control of nematodes in all filter sterilized B. megaterium H491 fermentations, the motility of root-knot nematode juveniles (J2's) was measured in an in vitro 96-well plastic cell-culture plate bioassay. This procedure is based on a visual grading of motility of the nematodes in each well treated with H491 where each treatment is tested in well repetitions of four: 100 ml of each microbial sample solution was dispensed into its corresponding well followed by 30 ml of a 1 : 100 dilution of plant preservative material (PPM) solution that momentarily suppresses microbial growth and allows visibility in each well. Finally, 50 ml of nematode solution, containing

approximately 15 J2's, was added. The plate was covered and incubated for 24 hours at

25°C, then the effect of each sample was visually scored and recorded. Nematicidal activity was confirmed in 19 different small scale fermentations, with nematicidal activity usually hovering over 60%, as summarized in Figure 5. B: Nematode (M. hapla) recovery after exposure to H491 supernatant

To assess the effect of H491 supernatant on the motility and subsequent recovery of juveniles of root-knot nematodes (Meloidogyne hapla), the following test was conducted on 96-well plastic cell-culture plates. A 50-ml aliquot of each test solution was added into appropriate wells after which, 50 J2s dispensed in 30 ml of deionized water were added into each well. The plate was closed with a lid, and incubated at 25°C for 72 hours. Water and Avid ^® nematicide (1 %) were used as negative and positive controls, respectively. The effect of each substance on nematode motility was determined after 24, 48, and 72 hours by adding a drop of 1 N NaOH into each well, and the proportion of motile nematodes in each treatment was recorded as a percentage of the initial number. To assess the recovery of motility in each treatment, a volume of 70 ml was removed from each well, and the remaining solution in each well was diluted by adding 100 ml of deionized water. Plates were again incubated for 24 hours as described above, after which the second motility evaluation was performed. There were three replications for each treatment and the study was conducted twice.

Results are shown in Table 4. After 48 hours, wells containing nematodes exposed to the highest amount of treatment solution were too cloudy to read without washing off the treatments. Therefore, percent of motile nematodes were not recorded directly after 48 or 72 hours. Percent of motile nematodes exposed to H491 supernatant was found to decrease with increased time of incubation. The lowest rate (17.5%) was observed 72 hours after incubation. These results indicate that H491 supernatant can immobilize juveniles of root- knot nematodes, and this effect can last for at least 72 hours.

Example 10: In vitro dose-response assay against free-living Nematodes

To evaluate the efficacy and stability of B. megaterium H491 whole cell broth, supernatant was tested for effect on J2 motility at different dilutions : IX = full strength; 0.75X= 75 ml H491 supernatant: 25 ml water; 0.50X= 50 ml H491 supernatant: 50ul water; 0.25X= 25 ml H491 supernatant: 75 ml water. The motility of juvenile root-knot nematodes (J2's) was measured in an in vitro 96-well plastic cell-culture plate dose-response bioassay. This procedure is based on a visual grading of motility of the nematodes in each well treated with H491 where each treatment is tested in well repetitions of four: 100 ml of each microbial sample dilution was dispensed into its corresponding well followed by 30 ml of a 1 : 100 dilution of plant preservative material (PPM) solution that temporarily suppresses microbial growth. Finally, 50 ml of nematode solution, containing approximately 15 M. hapla J2 nematodes, was added and the plate was covered and incubated at 25 °C for 24 hours. The effect of each dilution sample was then visually scored and recorded. The results, shown in Figure 6, indicate that the effect on motility ranged from about 15% non- motile at a four-fold dilution (0.25X), to 100% non-motile with full-strength supernatant (lx).

Example 11: Greenhouse Assays

A: Greenhouse pot assay: Cucumber with Meloidogyne incognita

To demonstrate the nematicidal activity of H491 supernatant against root knot nematodes {Meloidogyne incognita), a greenhouse study on cucumber (Cucumis sativus) cv. White Wonderwas conducted using a supernatant as the test productl. One cucumber plant per pot was planted in autoclaved sand and grown in a greenhouse under natural day light. Two-week-old plants were treated with an 40-mL aliquot of the test product, after which 2000 fresh hatched M. incognita J2s were inocuated into each pot. A week later, a second 40 mL portion of the test product was applied at the same rate as before. Water, media blank, and Avid (0.1%) were used as negative, negative, and positive controls, respectively. There were five replicates for each test product, and the experiment was arranged in a randomized complete block design. Plants were grown in a greenhouse for four more weeks, after which each plant was harvested and evaluated for fresh shoot and root weights. The number of nematodes in each pot, and the number of root gallson each plant, were recorded.

Data presented in Table 5 below show that, although cucumber shoot and root fresh weights from plants treated with H491 supernatant were not statistically different from untreated controls, the pots treated with H491 supernatant contain significantly fewer nematodes than the untreated control pots. In addition, root gall number in H491 supernatant-treated cucumber plants was significantly less than in plants treated with water or media blank control. These results indicate that H491 supernatant is effective in restraining gall formation by M. incognita in cucumber.

B: Greenhouse pot assay: Effect of H491 supernatant on Meloidogyne hapla -infestation of Cucumber and Tomato plants

Greenhouse studies on cucumber (Cucumis sativus) cv. White Wonder and tomato (Solanum lycopersicum) cv. Roma were performed to demonstrate the nematicidal activity of H491 supernatant on root knot nematodes (M. hapla). One cucumber or tomato plant per pot was planted in autoclaved sand and grown in a greenhouse under natural day light. Pots containing two-week-old cucumber or three-week-old tomato plants were treated with a 40- mL aliquot of the test product per pot, after which 2000 fresh M.hapla juvniles were inocuated into each pot. A week later, a second treatment of the test product was applied to the pots at the same rate as before. Water, media, and Avid (0.1 %) were used as negative, negative, and positive controls, respectively. There were five replicates for each test product, and the experiment was arranged in a randomized complete block design. Plants were grown in a greenhouse for four more weeks for cucumber and six more weeks for tomato, after which each plant was harvested and evaluated for fresh shoot and root weights and shoot height. Plant vigor and root galling index were rated on a 0-10 scale. For plant vigor, 0 represents dead and 10 represents most healthy; for root gall index, 0 represents no gall, and 10 represents 100% of roots galled. The number of nematodes in each pot was also recorded.

Results of the first trial are presented in Tables 6 and 7 for cucumber and tomato, respectively. H491 supernatant significantly reduced the root gall index in cucumber and the number of nematodes in cucumber and tomato compared with the water control. In the second trial, root gall index and number of nematodes were reduced by H491 in cucumber but not tomato (Tables 8 and 9). The results of both trials indicate that H491 supernatant reduces the number of galls in plants, and decreases the damage in plants from root-knot nematodes.

Example 12: Immobilization of Nematodes in Infested Soil

In this example, the effect of B. megaterium H491 supernatant on the motility and viability of nematodes in infested soil was determined. These trials were conducted with field soils infested predominantly with sting or lance nematodes. Each trial consisted of 4 treatments: H491 supernatant, growth medium blank, a positive control (i.e. 0.1% Avid ^® ) and a negative control (i.e. water). The trials were conducted as a randomized complete block design with 8 replications. Twelve liters of soil containing the desired nematodes were collected, separated from turf and roots, and homogenized. After mixing the soil, 5 (100 cm ³ ) soil samples were extracted using a centrifugation-sugar flotation method and, for each sample, the number of nematodes of each type was counted to ensure even distribution of the major nematodes of interest (sting or lance) throughout the soil. Next, 200 cm ³ portions of nematode-containing soil were measured out and placed into a 2 x 2 x 2-inch plastic pot. The treatments were applied as a drench treatment (40 ml/pot). The pots were then placed on a lab bench and left for 72 hours to expose the nematodes to the treatments.

Next, the soil from each pot was washed onto a modified Baermann apparatus for nematode extraction. The Baermann apparatus allows live nematodes to move out of the soil, through a filter, and into water, where they can be counted. Dead or immotile nematodes remain in the soil. After incubating the Baermanns for 96 hours, the live nematodes were collected and counted. Nematode counts from each treatment were compared with SAS 9.2 using Fisher's LSD mean separation at P≤ 0.05 for all nematodes observed.

The effects of H491 supernatant on four plant-parasitic nematode genera were determined. These four genera, observed in the field soil used to conduct the sting bench trial, were: sting nematode, lance nematode, Peltamigratus sp. and Scutellonema sp. Sting nematode counts were increased by 5% in soil exposed to growth medium, compared to soil exposed only to water. Compared to negative control (soil exposed to water) soil exposed to Avid or H491 supernatant experienced a 14% decrease in sting nematode number.

Peltamigratus sp. counts were decreased by 7%, 32%, and 88% after treatment of soil with medium, H491 supernatant and Avid, respectively; compared to the negative control (water). Scutellonema sp. counts were unchanged in the soil treated with growth medium, compared to the negative control (water), and decreased by 17% and 75% in soil treated with H491 and Avid, respectively, compared to the negative control (water). Lance nematode counts were decreased by 9%, 35%, and 69% in soil subjected to treatments with medium, H491 supernatant, and Avid, respectively, compared to the water control. Example 13: Extraction and isolation of compounds from B. megaterium H491 culture supernatant

The following procedure was used for the purification of compounds from cultures of B. megaterium. Briefly, a crude extract of B. megaterium H491 culture broth was extracted with Amberlite, and the crude extract was fractionated by vacuum liquid chromatography. An active VLC fraction was further fractionated by HPLC, and active compounds were identified. The nematicidally active compound 4-Phenylbutanoic acid (Compound 1) was obtained from VLC fraction 3, as described below.

Liquid chromatography of crude extract

The culture broth obtained from a 10-L fermentation of B. megaterium in V-8-broth was extracted with Amberlite XAD-7 resin (Asolkar et al., 2006) by shaking the cell suspension with resin at 225 rpm for two hours at room temperature. The resin and cell mass were collected by filtration through cheesecloth and washed with deionized water to remove salts. The resin, cell mass, and cheesecloth were then soaked for 2 h in

acetone/methanol (50/50) after which the acetone/me thanol was filtered and dried under vacuum, using a rotary evaporator, to yield a crude extract. The crude extract was fractionated by reversed-phase CI 8 vacuum liquid chromatography (H ₂ O/CH ₃ OH; gradient 80:20% to 0: 100%) into 6 fractions (Figure 1). These fractions were concentrated to dryness using a rotary evaporator, and the resulting dry residues were screened for biological activity using M. incognita and M. hapla.

Assay for biological activity of VLC fractions of Bacillus megaterium extract

VLC fractions 1-6 were dissolved in dimethylsulfoxide (DMSO)and tested in an in vitro 96-well plastic cell-culture plate extract bioassay to identify the fraction/s that contain the desired active metabolite/s. To test for biological activity, 15-20 J2 nematodes in 50 ml of water were exposed to 100 ml of a 4 mg/ml fraction concentrate for 24 hours at 25°C. Each fraction was tested in quadruplicate. Results were recorded based on a visual grading of immotility of the juvenile nematodes (J2's) in each well. Results are shown in Figure 7.

Reverse phase HPLC fractionation of VLC fractions

The active fractions were subjected to reversed phase HPLC on a Spectra System P4000 system (Thermo Scientific) to provide pure compounds, which were then screened in bioassays as described above to identify active compounds. To confirm the identity of the compounds, additional spectroscopic data such as LC/MS and NMR were recorded.

Fraction 3 (above) was applied to a HPLC C-18 column (Phenomenex, Luna lOu C18(2) 100 A, 250 x 30), and the column was developed with a water: acetonitrile gradient solvent system (0-10 min, 80-70 % aqueous CH ₃ CN; 10-45 min, 70-50 % aqueous CH ₃ CN; 45-55 min, 35-30 % aqueous CH ₃ CN; 55-60 min, 30-20 % aqueous CH ₃ CN; 60-65 min, 20- 0 % aqueous CH ₃ CN; 65-75 min, 100 % CH ₃ CN; 75-80 min, 0-80 % aqueous CH ₃ CN) at 7 mL/min flow rate with UV detection at 210 nm. The active compound 4-Phenylbutanoic acid (1), had a retention time 47.85 min.

Assay for biological activity of HPLC fractions

Each HPLC peak was tested in an in vitro 96-well plastic cell-culture plate extract bioassay in order to identify the peak/s that contain the desired active metabolite/s. For these assays, 15-20 nematodes in a 50 ml water solution were exposed to 3 ml of a 20 mg/ml peak concentrate for a 24 hour period at 25°C. Once the incubation period was completed, results were recorded based on a visual grading of immotility of the juvenile nematodes (J2's) in each well treated with H491 purified peaks H1-H38; each treatment was tested in well repetitions of four. The results, shown in Figure 8, indicate that H491 produces numerous compounds with pesticidal activity. Fraction 29 was selected for further analysis and testing.

Mass Spectroscopic Analysis of Compounds

Mass spectroscopy of active peaks, isolated by HPLC using the procedure set forth above, was performed on a Thermo Finnigan LCQ Deca XP Plus electrospray (ESI) instrument using both positive and negative ionization modes in a full scan mode (m/z 100- 1500 Da) on a LCQ DECA XP ^plus Mass Spectrometer (Thermo Electron Corp., San Jose, CA). Thermo high performance liquid chromatography (HPLC) instrument equipped with Finnigan Surveyor PDA plus detector, autosampler plus, MS pump and a 4.6 mm x 100 mm Luna C18 5μ 100A column (Phenomenex). The solvent system consisted of water (solvent A) and acetonitrile (solvent B). The mobile phase begins at 10% solvent B and was linearly increased to 100% solvent B over 20 min and then kept for 4 min, and finally returned to 10% solvent B over 3 min and kept for 3 min. The flow rate was 0.5 mL/min. The injection volume is 10 uL and the samples were kept at room temperature in an auto sampler. The compounds were analyzed by LC-MS utilizing the LC and reversed phase chromatography. Mass spectroscopy analysis of the present compounds is performed under the following conditions: The flow rate of the nitrogen gas was fixed at 30 and 15 arb for the sheath and aux/sweep gas flow rate, respectively. Electrospray ionization was performed with a spray voltage set at 5000 V and a capillary voltage at 35.0 V. The capillary temperature was set at 400°C. The data was analyzed on Xcalibur software. The 4-Phenylbutanoic acid (1) exhibited a molecular mass of 163.34 in negative ionization mode (see Figure 2).

NMR Spectroscopic Analysis o f Compounds

NMR spectra were measured on a Bruker 600 MHz gradient field spectrometer. The reference is set on the internal standard tetramethylsilane (TMS, 0.00 ppm).

For structure elucidation, the purified 4-Phenylbutanoic acid (1) with molecular weight 164 was further analyzed using a 600 MHz NMR instrument. ^] H NMR δ values at 7.28 (2H), 7.19 (2H), 7.17, 2.67, 2.31, and 1.92 were detected (see Figure 3). ¹³ C NMR values of 177.5, 142.9, 129.5, 129,5, 129.4, 129.4, 126.9, 36.1, 34.4, and 28 were detected (see Figure 4). The active compound was isolated as a colorless solid, with UV absorption bands at 220 & 283 nm. The negative electrospray ionization mass spectrum revealed molecular ion peak at m/z 163.32 [M - H] ^~ and 327.14 [2M - H] ^~ suggesting a molecular weight of 164, which is consistent with the molecular formula C ₁₀ H ₁₀ O ₂ (with 5 degrees of unsaturation). The ^] H NMR spectrum exhibited signals indicative of the presence of a mono substituted aromatic ring (δ 7.28, 2H, d, J = 7.7 Hz; 7.19, 2H, d, J = 7.7 Hz; 7.17 1H, t, J = 7.7 Hz). Furthermore, the ^] H NMR spectrum revealed the presence of three methylene groups, at δ 2.62, 2H, t, J = 7.92 Hz, 2.30, 2H, t, J = 7.65 and 1.92, 2H, q, / = 7.65 Hz. The ¹³ C NMR spectrum of Compound (1), interpreted with the help of the HSQC experiment, indicated the presence of 10 carbon atoms, including one carbonyl (5 _C 177.5); six sp ² carbons, one of which is unprotonated (5 _C 142.9); five protonated carbon atoms (5 _C 129.5, 129.5, 129.4, 129.4, 126.9); and three methylenes (5 _C 36.1, 34.4, 28.1). The analysis of the COSY and HSQC correlation revealed two spin systems, one involving three methylene groups of the structure -CH ₂ -CH ₂ -CH ₂ -, and the other comprising a mono substituted benzene ring. From the detailed analysis of COSY, HMQC and HMBC experiments, the structure for the compound was assigned as 4-phenylbutanoic acid. The assigned structure was confirmed by comparison with a synthetic sample. This compound has been isolated from the marine bacterium B. pumilus S6-15, which inhibits biofilm formation in gram positive and gram negative species (Nithya et al., 2011).

Example 14: Greenhouse cone assay: effect of Meloidogyne incognita on tomato seedlings

Greenhouse studies on tomato {Solanum lycopersicum) cv. UC 82 were performed to test the nematicidal activity of H491 supernatant on root knot nematodes (M. incognita). One 25-day-old tomato seedling per cone container (Stuewe & Sons, Inc, Tangent, OR) was transplanted into autoc laved sand and soil mix (2: 1) and grown in a greenhouse under natural day light. 16 days after transplanting, each tomato seedlings (3-4 true leaves) was drenched with a 10-ml aliquot of whole cell broth (WCB) of H491 and other test products by pouring the aliquot directly onto the soil surface. Thereafter, 4000 eggs of M. incognita suspended in 1 ml of water were inoculated into three 6-cm-deep holes around the stems in each cone. A week later, a second drench was applied to the cones at the same rate as the first drench. Water and Avid (625 ppm) were used as negative and positive controls, respectively. There were four replicates and the experiment was arranged in a randomized complete block design. Plants were grown in a greenhouse for 3 weeks before being taken down. Each plant was then evaluated for phytotoxicity, fresh top (or shoot) weight, fresh root weight, gall numbers per root and gall index based on a 0 tolO scale (0 = no galls, 10 = 100% of roots galled). There was no phytotoxicity observed during the incubation period of the test. Statistical analysis (ANOVA) was perfomed using Fisher test, and the statistical differences among treatment means were calculated at P < 0.05.

Results are presented in Table 10. H491 WCB significantly reduced the gall index, number of galls per root and number of galls per gram of root compared with the water control. The plants treated with H491 had heavier fresh topweight than those treated with water. No signficant difference was observed on the fresh root weight between treatments.

H491 Bacillus megaterium whole cell broth (WCB) was tested in an in planta bioassay at 3 different dilutions in water (IX, 0.7X, and 0.5X v/v ) to determine the potency of the WCB against Meloidogyne incognita juveniles. This test is a miniature greenhouse pot test in which sterile falcon tubes were modified by cutting the top 1.5 inches off and making holes in the bottom to allow drainage. The tubes were filled with a mixture of sand and soil (1 :2) and drenched with 2 mL aliquots of H491 whole cell broth (50, 70 and 100%), Avid (label rate) as positive control, and water as negative control. After drenching, cucumber seeds (cv. SMR58) were planted and then the tubes were inoculated with 800 eggs of M. incognita. The tubes were covered with parafilm and placed in a box with wet paper towels to ensure high humidity. After 4 days, most of the seed had germinated and the parafilm cover was removed. After one week, a second dose (1 mL) was applied. The test was terminated after two weeks and fresh top weight, fresh root weight and gall index (scale: 1 unhealthy roots - 10 healthy roots) were assessed. The results, shown in Figure 10, indicate that gall index was reduced at all concentrations of H491 whole cell broth tested.

Example 16: In vitro motility assay

H491 WCB obtained from four separate fermentation batches was tested in an in vitro motility assay. In this assay, M. incognita juveniles (J2) were exposed to test samples in a 96-well flat bottom plate. After 24 hours the juveniles were transferred into 6-well plates containing 1.5% water agar, to allow potential recovery. Motility was measured by counting the number of juveniles (J2) that moved out of the initial area after another 24 hours. The results are shown in Figure 11. The data indicates that, for all four batches of H491 WCB, 100% immobilization was achieved after 24 hour exposure.

Example 17: Plant growth promotion capabilities of B. megaterium H491

B. megaterium H491 was tested for plant growth promotion markers on five different plate assays, and representative results are shown in Table 11. The bacterium was able to solubilize phosphate and produced the enzyme ACC deaminase. It was also capable of growing on methanol as carbon source. These results suggested that B. megaterium H491 can promote growth and confer stress tolerance to plants.

Example 18: Growth promoting activity on soy and sorghum

To test for the ability of B. megaterium H491 to promote plant growth, two seedling vigor assays were performed on soy and sorghum. Strain H491 was grown on an agar plate and a few colonies were transferred to 50 ml sterile Luria broth (LB : 25 g/1) and incubated at 25°C, 180 rpm for 24 h. Bacterial cells were harvested from the LB cultures by centrifugation at 3220 x g for 20 minutes. The supernatant was discarded and the cells were washed in 20 ml sterile MgS0 ₄ buffer then centrifuged for a second time at 3220 x g for 20 minutes. After discarding the supernatant, the cells were re-suspended in a small volume of sterile buffer. The concentration of cells in the suspension was determined by measuring the absorbance at 600 nm in a spectrophotometer. Seeds were treated with the cell suspension by imbibition. A cell inoculum (1 x 10 ⁸ CFU/ml) was dispensed over the seeds, in a 50 ml Falcon tube, at a rate of 0.6 ml per gram of seed (for seed with 250-300 seed/g). The seed and inoculum were incubated overnight at 25°C, and treated seeds were then dried in a sterile hood for 30 min. The negative control was prepared in the same manner, except the cell inoculum was replaced with sterile buffer. Growth promotion was evaluated by measuring fresh weight of seedlings, as shown in Table 12. For soy, the seedling weight doubled with the H491 treatment. For sorghum, a 64% increase of the fresh weight was observed.

Example 19: Growth promoting activity on corn

Corn seeds were planted and drenched at planting time and one week after planting with B. megaterium H491 whole cell broth (WCB). A total of 10 plants per pot and 9 pots per treatment were planted and evaluated. Total fresh weight was recorded 2 weeks after planting, and statistical analysis was performed using Minitab ANOVA Tukey's.

The results are shown in Table 13. In corn plants treated with H491 WCB, a significant increase in vegetative fresh weight was observed, with a 95%simultaneous confidence interval as assessed by Tukey's.

Example 20: Effect of Compound 1 on nematode motility

HPLC fraction H29 (Example 13 and Figure 8) was determined to be 4- phenylbutanoic acid. In this example, 4-phenylbutanoic acid (Compound 1) was synthesized and tested for dose-response in a nematode motility assay. M. incognita juveniles (J2) were exposed to different concentrations of 4-phenylbutanoic acid in a 96- well flat bottom plate for 24 hours. Juveniles were then transferred into 6- well plates containing 1.5% water agar to allow recovery. After a further 24 hours, motility was determined by counting the number of juveniles (J2) that had moved out of the initial area. Water and DMSO were used as negative controls, and Avid as a positive control.

The results are shown in Figure 12. Using 75% immotility as a threshold for nematicidal activity, concentrations of 4-phenylbutanoic acid of 0.017 mg/ml or greater provided substantial nematicidal activity. Example 22: Nematicidal activity of three isolates of B. megaterium

Isolates of B. megaterium H491, M018 and J 142 were cultured. Whole cell broth from each of the three cultures was tested in the water agar immotility assay described in Example 21. The results, shown in Figure 13, indicate that whole cell broth from all three of the strains are able to render essentially 100% of juveniles immotile.
