ENZYME COMPOSITION AND USES THEREOF

TECHNICAL FIELD

The present invention relates to enzyme compositions and processes of producing sugars and/or fermentation products from starch-containing materials using such enzyme compositions.

BACKGROUND ART

Processes of producing sugars and fermentation products, such as ethanol, from starch-containing materials are well-known in the art and used commercially today.

When producing fermentation products, such as ethanol, starch is conventionally converted into dextrins using a liquefying enzyme (e.g., Bacillus alpha-amylase) at temperatures above the initial gelatinization temperature of starch to above 100°C. The generated dextrins are hydrolyzed into sugars using a saccharifying enzyme (e.g., glucoamylase) and fermented into the desired fermentation product using a fermenting organism such as a yeast strain derived from Saccharomyces cerevisiae. Typically hydrolysis and fermentation are done in a simultaneous saccharification and fermentation (SSF) step.

Another type of process is also used commercially today. Starch is converted into dextrins at temperatures below the initial gelatinization temperature of starch and hydrolyzed into sugars during SSF. This type of process is referred to as a raw starch hydrolysis (RSH) process, or alternatively a "one-step process" or "no cook" process.

Process of the Invention

As mentioned above an enzyme composition of the invention may suitably be used in

25 a raw starch hydrolysis (RSH) process for producing desired sugars and fermentation products. In RSH processes the starch does not gelatinize as the process is carried out at temperatures below the initial gelatinization temperature of the starch in question.

The desired fermentation product may in an embodiment be ethanol produced from un-gelatinized (i.e., uncooked), preferably milled, grains, such as corn, or small grains such

30 as wheat, oats, barley, rye, rice, or cereals such as sorghum. Examples of suitable starch- containing starting materials are listed in the section "Starch-Containing Materials' -section below.

Accordingly, in this aspect the invention relates to processes of producing fermentation products from starch-containing material comprising:

35 (i) saccharifying a starch-containing material at a temperature below the initial gelatinization temperature; and

(ii) fermenting using a fermentation organism;

wherein saccharification and/or fermentation is done in the presence of the following enzymes: glucoamylase and alpha-amylase, and optionally a protease.

In an embodiment the glucoamylase is the Gloeophyllum trabeum glucoamylase shown in SEQ ID NO: 18 herein having one or more of the following substitutions: S95P, A121 P, preferably S95P+A121 P and the alpha-amylase derived from Rhizomucor pusillus with an Aspergillus niger glucoamylase linker and starch-binding domain (SBD), shown in SEQ ID NO: 13 herein, having one or more of the following substitutions: G128D, D143N, preferably G128D+D143N.

In a preferred embodiment the invention relates to processes of producing fermentation products from starch-containing material comprising:

(a) saccharifying a starch-containing material at a temperature below the initial gelatinization temperature; and

(b) fermenting using a fermentation organism;

wherein saccharification and/or fermentation is done in the presence of the following enzymes:

i) glucoamylase;

ii) alpha-amylase;

iii) cellulolytic enzyme composition;

iv) optionally protease.

In a preferred embodiment the enzyme may be added as an enzyme composition of the invention. In a preferred embodiment steps (a) and (b) are carried out simultaneously (i.e., one-step fermentation). However, step (a) and (b) may also be carried our sequentially.

According to this aspect of the invention a desired fermentation product, such as ethanol, may be produced without liquefying the aqueous slurry containing the starch- containing material. The process of the invention includes saccharifying (e.g., milled) starch- containing material, e.g., granular starch, below the initial gelatinization temperature, preferably in the presence of an enzyme composition of the invention. The sugars generated during saccharification can be simultaneously fermented into the desired fermentation product by suitable fermenting organism(s).

In a preferred embodiment a cellulolytic enzyme composition is one described above in the "Cellulolytic Enzyme Composition"-section. Preferably the cellulolytic enzyme composition is added to the process of the invention.

In a preferred embodiment the cellulolytic enzyme composition is comprised in an enzyme composition of the invention.

In an embodiment the glucoamylase and alpha-amylase are added as one blend composition and the cellulolytic enzyme composition and optional protease are added separately. In another embodiment the cellulolytic enzyme composition, the glucoamylase, and the alpha-amylase are added as one enzyme composition and the optional protease is added separately. All enzymes may be added as one enzyme composition comprising a glucoamylase, an alpha-amylase, optionally a cellulolytic enzyme composition, and/or a protease, and optionally other enzymes including pullulanase and/or pectinase, such as pectin lyase or polygalacturonase.

The fermentation product, such as especially a liquid fermentation product, such as ethanol, may optionally be recovered after fermentation, e.g., by distillation. Subsequent to fermentation the fermentation product may be separated from the fermentation medium. The fermentation medium may be distilled to extract the desired fermentation product or the desired fermentation product may be extracted from the fermentation medium by micro or membrane filtration techniques. Alternatively, the fermentation product may be recovered by stripping. Methods for recovering fermentation products are well known in the art.

An example of a fermenting organism is yeast, preferably a strain of Saccharomyces cerevisiae. Saccharomyces cerevisiae may according to the invention be used for producing ethanol. Other suitable fermenting organisms are listed in the "Fermenting Organisms"- section below.

The term "initial gelatinization temperature" means the lowest temperature at which starch gelatinization commences. In general, starch heated in water begins to gelatinize between about 50°C and 75°C. The exact temperature of gelatinization depends on the specific starch and depends on the degree of cross-linking of the amylopectin. The initial gelatinization temperature can readily be determined by the skilled artisan. The initial gelatinization temperature may vary according to the plant species, to the particular variety of the plant species as well as with the growth conditions. In context of this invention the initial gelatinization temperature of a given starch-containing material may be determined as the temperature at which birefringence is lost in 5% of the starch granules using the method described by Gorinstein. S. and Lii. C, Starch/Starke, Vol. 44 (12) pp. 461-466 (1992).

Before step (a) an aqueous slurry of starch-containing material, such as granular starch, having 10-55 wt.-% dry solids (DS), preferably 25-45 wt.-% dry solids, more preferably 30-40% dry solids of starch-containing material may be prepared. The slurry may include water and/or process waters, such as stillage (backset), scrubber water, evaporator condensate or distillate, side-stripper water from distillation, or process water from other fermentation product plants. Because the process of the invention is carried out below the 5 initial gelatinization temperature and thus no significant viscosity increase takes place, high levels of stillage may be used, if desired. In an embodiment the aqueous slurry contains from about 1 to about 70 vol.-%, preferably 15-60% vol.-%, especially from about 30 to 50 vol.-% water and/or process waters, such as stillage (backset), scrubber water, evaporator condensate or distillate, side-stripper water from distillation, or process water from other

10 fermentation product plants, or combinations thereof, or the like.

In an embodiment backset, or another recycled stream, is added to the slurry before step (a), or to the saccharification (step (a)), or to the simultaneous saccharification and fermentation steps (combined step (a) and step (b)).

After being subjected to a process of the invention at least 85%, at least 86%, at least

15 87%, at least 88%, at least 89%, at least 90%, at least 91 %, at least 92%, at least 93%, at least 94%, at least 95%, at least 96%, at least 97%, at least 98%, or preferably at least 99% of the dry solids in the starch-containing material are converted into a soluble starch hydrolysate.

A process of the invention is conducted at a temperature below the initial 20 gelatinization temperature, which means that the temperature at which a separate step (a) is carried out typically lies in the range between 25-75°C, such as between 30-70°C, or between 45-60°C.

In a preferred embodiment the temperature during fermentation in step (b) or simultaneous saccharification and fermentation in steps (a) and (b) is between 25°C and 25 40°C, preferably between 28°C and 36°C, such as between 28°C and 35°C, such as between 28°C and 34°C, such as around 32°C.

In an embodiment of the invention fermentation is carried out for 30 to 150 hours, preferably 48 to 96 hours. 66.

In an embodiment fermentation is carried out so that the sugar level, such as glucose 30 level, is kept at a low level, such as below 6 wt.-%, such as below about 3 wt.-%, such as below about 2 wt.-%,such as below about 1 wt.-%., such as below about 0.5%, or below 0.25% wt.-%, such as below about 0.1 wt.-%. Such low levels of sugar can be accomplished by simply employing adjusted quantities of enzymes and fermenting organism. A skilled person in the art can easily determine which doses/quantities of enzyme and fermenting 35 organism to use. The employed quantities of enzyme and fermenting organism may also be selected to maintain low concentrations of maltose in the fermentation broth. For instance, the maltose level may be kept below about 0.5 wt.-%, such as below about 0.2 wt.-%.

The process of the invention may be carried out at a pH from 3 and 7, preferably from 3 to 6, or more preferably from 3.5 to 5.0.

The term "granular starch" means raw uncooked starch, i.e., starch in its natural form found in, e.g., cereal, tubers or grains. Starch is formed within plant cells as tiny granules insoluble in water. When put in cold water, the starch granules may absorb a small amount of the liquid and swell. At temperatures up to around 50°C to 75°C the swelling may be reversible. However, at higher temperatures an irreversible swelling called "gelatinization" begins. The granular starch may be a highly refined starch, preferably at least 90%, at least 95%, at least 97% or at least 99.5% pure, or it may be a more crude starch-containing materials comprising (e.g., milled) whole grains including non-starch fractions such as germ residues and fibers.

The raw material, such as whole grains, may be reduced in particle size, e.g., by milling, in order to open up the structure and allowing for further processing. Examples of suitable particle sizes are disclosed in US4514496 and WO2004/081 193 (incorporated by reference). Two processes are preferred according to the invention: wet and dry milling. In dry milling whole kernels are milled and used. Wet milling gives a good separation of germ and meal (starch granules and protein) and is often applied at locations where the starch hydrolysate is used in production of, e.g., syrups. Both dry and wet milling is well known in the art of starch processing.

In an embodiment the particle size is reduced to between 0.05 to 3.0 mm, preferably 0.1 -0.5 mm, or so that at least 30%, preferably at least 50%, more preferably at least 70%, even more preferably at least 90% of the starch-containing material fit through a sieve with a 0.05 to 3.0 mm screen, preferably 0.1-0.5 mm screen. In a preferred embodiment starch- containing material is prepared by reducing the particle size of the starch-containing material, preferably by milling, such that at least 50% of the starch-containing material has a particle size of 0.1-0.5 mm.

Measurement of Cellulase Activity Using Filter Paper Assay (FPU assay)

1. Source of Method

1.1 The method is disclosed in a document entitled "Measurement of Cellulase Activities" by Adney, B. and Baker, J. 1996. Laboratory Analytical Procedure, LAP-006, National

Renewable Energy Laboratory (NREL). It is based on the lUPAC method for measuring cellulase activity (Ghose, T.K., Measurement of Cellulse Activities, Pure & Appl. Chem. 59, pp. 257-268, 1987.

2. Procedure

2.1 The method is carried out as described by Adney and Baker, 1996, supra, except for the use of a 96 well plates to read the absorbance values after color development, as described below.

2.2 Enzyme Assay Tubes:

2.2.1 A rolled filter paper strip (#1 Whatman; 1 X 6 cm; 50 mg) is added to the bottom of a test tube (13 X 100 mm).

2.2.2 To the tube is added 1.0 mL of 0.05 M Na-citrate buffer (pH 4.80).

2.2.3 The tubes containing filter paper and buffer are incubated 5 min. at 50° C (± 0.1 ° C) in a circulating water bath.

2.2.4 Following incubation, 0.5 mL of enzyme dilution in citrate buffer is added to the tube.

Enzyme dilutions are designed to produce values slightly above and below the target value of 2.0 mg glucose.

2.2.5 The tube contents are mixed by gently vortexing for 3 seconds.

2.2.6 After vortexing, the tubes are incubated for 60 mins. at 50° C (± 0.1 ° C) in a circulating water bath. 2.2.7 Immediately following the 60 min. incubation, the tubes are removed from the water bath, and 3.0 mL of DNS reagent is added to each tube to stop the reaction. The tubes are vortexed 3 seconds to mix.

2.3 Blank and Controls

2.3.1 A reagent blank is prepared by adding 1.5 mL of citrate buffer to a test tube.

2.3.2 A substrate control is prepared by placing a rolled filter paper strip into the bottom of a test tube, and adding 1.5 mL of citrate buffer.

2.3.3 Enzyme controls are prepared for each enzyme dilution by mixing 1 .0 mL of citrate buffer with 0.5 mL of the appropriate enzyme dilution.

2.3.4 The reagent blank, substrate control, and enzyme controls are assayed in the same manner as the enzyme assay tubes, and done along with them.

2.4 Glucose Standards

2.4.1 A 100 mL stock solution of glucose (10.0 mg/mL) is prepared, and 5 mL aliquots are frozen. Prior to use, aliquots are thawed and vortexed to mix.

2.4.2 Dilutions of the stock solution are made in citrate buffer as follows:

G1 = 1.0 mL stock + 0.5 mL buffer = 6.7 mg/mL = 3.3 mg/0.5 mL

G2 = 0.75 mL stock + 0.75 mL buffer = 5.0 mg/mL = 2.5 mg/0.5 mL

G3 = 0.5 mL stock + 1.0 mL buffer = 3.3 mg/mL = 1.7 mg/0.5 mL

G4 = 0.2 mL stock + 0.8 mL buffer = 2.0 mg/mL = 1.0 mg/0.5 mL

2.4.3 Glucose standard tubes are prepared by adding 0.5 mL of each dilution to 1.0 mL of citrate buffer.

2.4.4 The glucose standard tubes are assayed in the same manner as the enzyme assay tubes, and done along with them.

2.5 Color Development

2.5.1 Following the 60 min. incubation and addition of DNS, the tubes are all boiled together for 5 mins. in a water bath.

2.5.2 After boiling, they are immediately cooled in an ice/water bath.

2.5.3 When cool, the tubes are briefly vortexed, and the pulp is allowed to settle. Then each tube is diluted by adding 50 microL from the tube to 200 microL of ddH20 in a 96-well plate. Each well is mixed, and the absorbance is read at 540 nm.

2.6 Calculations (examples are given in the NREL document)

2.6.1 A glucose standard curve is prepared by graphing glucose concentration (mg/0.5 mL) for the four standards (G1 -G4) vs. A ₅₄₀ . This is fitted using a linear regression (Prism Software), and the equation for the line is used to determine the glucose produced for each of the enzyme assay tubes. 2.6.2 A plot of glucose produced (mg/0.5 ml.) vs. total enzyme dilution is prepared, with the Y-axis (enzyme dilution) being on a log scale.

2.6.3 A line is drawn between the enzyme dilution that produced just above 2.0 mg glucose and the dilution that produced just below that. From this line, it is determined the enzyme dilution that would have produced exactly 2.0 mg of glucose.

2.6.4 The Filter Paper Units/mL (FPU/mL) are calculated as follows:

FPU/mL = 0.37/ enzyme dilution producing 2.0 mg glucose

Protease Assay method - AU(RH)

The proteolytic activity may be determined with denatured hemoglobin as substrate. In the Anson-Hemoglobin method for the determination of proteolytic activity denatured hemoglobin is digested, and the undigested hemoglobin is precipitated with trichloroacetic acid

(TCA). The amount of TCA soluble product is determined with phenol reagent, which gives a blue color with tyrosine and tryptophan.

One Anson Unit (AU-RH) is defined as the amount of enzyme which under standard conditions (i.e. 25°C, pH 5.5 and 10 min. reaction time) digests hemoglobin at an initial rate such that there is liberated per minute an amount of TCA soluble product which gives the same color with phenol reagent as one milliequivalent of tyrosine.

The AU(RH) method is described in EAL-SM-0350 and is available from Novozymes A/S Denmark on request.

Protease assay method (LAPU)

1 Leucine Amino Peptidase Unit (LAPU) is the amount of enzyme which decomposes 1 microM substrate per minute at the following conditions: 26 mM of L-leucine-p-nitroanilide as substrate, 0.1 M Tris buffer (pH 8.0), 37°C, 10 minutes reaction time.

LAPU is described in EB-SM-0298.02/01 available from Novozymes A/S Denmark on request.

Determination of Maltogenic Amylase activity (MANU)

One MANU (J altogenic Amylase Novo Unit) may be defined as the amount of enzyme required to release one micro mole of maltose per minute at a concentration of 10 mg of maltotriose (Sigma M 8378) substrate per ml of 0.1 M citrate buffer, pH 5.0 at 37°C for 30 minutes. EXAMPLES Example 1

Approximately 795 g yellow dent corn (obtained from Lincolnway Ethanol; ground in- house Turkish grind setting on Bunn coffee grinder) was added to 1205 g tap water and the dry solids (DS) level was determined to be 34.64% (see below for method). This mixture was supplemented with 3 ppm penicillin and 500 ppm urea. The slurry was adjusted to pH 4.5 with 40% H ₂ S0 ₄ . Approximately 5 g of this slurry was added to 15 mL tubes. Each tube was dosed with enzymes according to Table 1 , followed by 100 μΙ_ of rehydrated yeast (5.5 g Fermentis Ethanol Red yeast in 100 mL H ₂ 0, incubated for 30 min at 32°C with magnetic stirring). Table 2 shows the enzymes used for this experiment. Water was added to each tube to bring the total added volume (enzyme + water) to 5.3% of the initial weight of the mash. This volume correction brings all tubes in the experiment to the same total percent solids, making ethanol concentrations directly comparable between treatments.

Table: Dosing Scheme Actual enzyme dosages were based on the exact weight of corn slurry in each tube according to the following formula:

Final enz. dose (mg/g DS) Mash weight (g) Dry solid content (%DS) 1000

Tubes were incubated at 32°C and 6 replicate fermentations of each treatment were run. All tubes were vortexed at 24, 48 and 70 hours. Three samples were sacrificed for HPLC analysis at 72 hours, and 3 at 88 hours. The HPLC preparation consisted of stopping the reaction by addition of 50 μί of 40% H ₂ S0 ₄ , centrifuging for 10 min at 1462xg, and filtering through a 0.45 μηη filter. Samples were stored at 4°C.
