TECHNICAL FIELD

The present invention relates to a wild-type, non-engineered, microbial lipolytic enzyme with a high specificity for short-chain fatty acids, preferably with a higher specificity for short chain fatty acids than for medium to long chain fatty acids, preferably when compared to a known microbial lipolytic enzyme, a nucleic acid encoding said lipolytic enzyme, a vector, a host cell and/or a composition comprising the lipolytic enzyme. This invention also relates to a process for preparing a food product, such as a dairy product, wherein the lipolytic enzyme is used.

This invention is suitable for use in the food industry, preferably in the dairy industry, more preferably in the cheese industry leading, for example, to flavor enhancement or shortening of the ripening times for ripened cheeses.

BACKGROUND

Lipolytic enzyme also called lipases (EC 3.1.1.3) are a class of hydrolases that hydrolyze ester bonds of lipids of triglycerides generating free fatty acids. This class of enzymes is responsible, for example, for the lipolysis of milk fat and/or other fat and subsequent release of short (C4- to C ₆ -fatty acids), medium and/or long (Cs- and higher) chain fatty acids.

Each lipolytic enzyme has its own release profile of free fatty acids from milk fat and/or other fat. This profile may range from short (C4- to C ₆ -fatty acids), to medium and/or long (Cs- and higher) chain fatty acids. The mixture of short (C4- to C ₆ -fatty acids), medium and/or long (Cs- and higher) chain fatty acids obtained is dependent, at least, on the lipolytic enzyme and on the lipolytic substrate. The mixture of short (C4- to C ₆ -fatty acids), medium and/or long (Cs- and higher) chain fatty acids obtained is responsible for modulating the flavor of a given final product. For example, a mixture having a higher amount or concentration of short chain fatty acids, such as a higher amount or concentration of butyric acid (C4-fatty acid), than an amount or concentration of medium and/or long chain fatty acids leads to the development of a preferred rancid cheese flavor, in particular during ripening, and has been used for flavor generation in dairy products, for example in various cheese types. In contrast, a mixture having a higher amount or concentration of medium and/or long chain fatty acids, specially a mixture having a higher amount or concentration of long chain fatty acids (C16- and higher), than an amount or concentration of short chain fatty acids gives rise to off flavors.

Lipolytic enzymes or lipases can be of animal origin or non-animal origin. Lipases from animal origin (kid goat, calf or lamb) preferably cleave short chain fatty acids (C4- to C ₆ -fatty acids) from milk fat and/or other fat rather than long chain fatty acids. These short chain fatty acids, in particular C^fatty acids, are responsible for the formation of the preferred rancid taste rather than the soapy taste produced by the medium to long chain fatty acids. To lesser extent they also release medium chain fatty acids, which add animal specific taste to the cheese. Nevertheless, lipases from animal origin cannot be used in vegetarian and/or kosher products, which is a highly demanded market. On the other hand, lipases from non-animal origin, such as from microbial origin, fully fulfill the vegetarian and/or kosher requirements, however microbial lipases are known for being non-specific lipases mainly releasing medium to long chain fatty acids (Cs- and higher) from milk fat and/or other fat, thereby giving cheese an extremely unpleasant soapy taste.

Therefore, there is a driver in the food industry, especially in the cheese industry, to look for a new source of a microbial wild-type, non-engineered, lipase presenting a higher specificity towards short chain fatty acids, such as C^fatty acids and/or C ₆ -fatty acids, than towards medium or long chain fatty acids, and/or to look for a new source of a microbial wild-type, non-engineered, lipase presenting a higher specificity towards short chain fatty acids, such as C4-fatty acids and/or C ₆ -fatty acids, and additionally a specificity towards medium chain fatty acids, such as Cs- or Cio-fatty acids, than towards long chain fatty acids.

Several attempts to replace animal lipases are known in the prior art. These attempts include the use of microbial lipases, recombinant lipases and/or genetic engineered lipases. However, these attempts have failed to deliver a microbial wild-type lipase with a higher specificity towards short chain fatty acids, preferably towards C^fatty acids, and a desirable flavor development in food products such as in cheese.

Microbial lipases can be obtained, for example, from Aspergillus, Rhizopus, and Mucor. The effect of these fungal lipases for developing rancidity in fats with respect to Aspergillus is disclosed by Iwai et al. in J. Gen. Appl. Microbiol. 10, 13-22 (1964), US 4 726 954 or US 4 636 468; with respect to Rhizopus is described by Oi et al. in Agr. Biol. Chem. 33, 729-38 (1969); and with respect to Mucor is set forth by Somkuti et al. in Appl. Microbiol. 16, 617- 19 (1968). All the mentioned lipases have a higher specificity towards medium to long chain fatty acids, such as Aspergillus or Rhizopus, or towards medium chain fatty acids, as it is the case of Mucor, than towards short chain fatty acids, such as C4- to C6-fatty acids.

Microbial lipases can also be obtained from Yarrowia, such as Yarrowia (Y.) lipolytica. Several documents disclose the preference of lipases from Yarrowia towards medium to long chain fatty acids. For example, Kamoun et al. 2015 describes a higher specificity for trioctanoin than for tributyrin at pH 7.5 for Lip8; Aloulou et al. 2007 discloses a higher specificity for trioctanoin than for tributyrin at pH 6 for Lip2; Sheng, J., et al. 2012 mentions the LipY has the highest activity on Cs-Ci2 fatty acids. US2005059130 (or EP 2 290 059) also describes microbial lipases derived from Humicola lanuginosa, Fusarium oxysporum or Rhizomucor miehei (examples 10, 11 or 12, respectively), wherein the substrate specificity of the wild type enzymes was modified by making alterations to the amino acid sequences of said lipases and as such obtain variants with increased specificity for short-chain fatty acids. EP 3 081 644 discloses a modified lipase from Candida cylindracea also having higher specificity towards short-chain fatty acids. However, none of these microbial engineered lipases is a naturally occurring lipase with a higher specificity for short chain fatty acids than for medium to long chain fatty acids.

The foregoing illustrates the difficulty in obtaining a microbial wild-type lipase with higher specificity towards short chain fatty acids, specially towards C^fatty acids, and a lower specificity towards medium and/or long chain fatty acids, specially a lower specificity towards long chain fatty acids, leading to a reduction in soapiness and an increase in butyric flavors in a food product, such as a dairy product or cheese, and therefore able to replace the microbial lipases currently available.

SUMMARY OF THE INVENTION

The present invention provides a novel wild-type, microbial lipolytic enzyme suitable to be used in the food industry, preferably in the dairy industry, more preferably in the cheese industry. Surprisingly the enzymes herein disclosed have a higher specificity towards short chain fatty acids, in particular C^fatty acids and/or C ₆ -fatty acids, when compared to a known microbial lipolytic enzyme under the same conditions, in particular for the same dosage of enzyme and in the same fat matrix, meaning that these enzyme release or produce or generate more short chain fatty acids than known microbial enzyme(s). This is completely unexpected as, until now, wild-type microbial lipolytic enzymes were known to be specific towards medium or long chain fatty acids and not short chain fatty acids, preferably not specific towards C^fatty acids and/or C ₆ -fatty acids.

The "lipase activity" may be determined, for dosing in cheese and cream, for example by the International Dairy Federation (IDF) method for both the commercial lipase and the enzymes herein disclosed (SEQ ID NO 1-11). The IDF method, mainly, corresponds to the International Standard ISO 13082:2011, 1 ^st edition of 2011-11-15, IDF 218:2011 (also labelled as ISO 13082|218). However, in the present invention, the term "LFU/L of milk" is used. The term "LFU/L of milk" relates to the concentration or amount of enzyme or dosage of enzyme per liter of milk used to produce a dairy product, such as cheese. In the context of the present invention "LFU/L of milk" means lipase forestomach units per liter of milk. One LFU is defined as the amount of lipase activity that releases butyric acid at a rate of 1.25 pmol/min, under the tested conditions. Further, the lipase activity may also be determined as explained in the Examples below. Finally, there are other methods of determining lipase activity which has been disclosed in prior art documents (such as in EP 3 081 644, EP 2 254 996 or EP 1 776 455). However, what is relevant is that within the same example or within comparative examples, the lipase activity is determined in the same way for all lipases under analysis, including the control lipase.

The term "wild type" lipase means, in the context of the present invention, a lipase whose sequence has not been mutated, i.e. does not contain amino acid deletions, additions or substitutions, when compared with a mature protein sequence (after co- and/or post- translational cleavage events) endogenously produced. Wild type lipases of the present invention may be encoded by codon optimized polynucleotides for heterologous expression and may also comprise a non-endogenous signal- and/or propeptide selected for expression in a given host. Furthermore, in the present invention, a lipase may also be synthetically obtained or genetically modified, using methods well known in the art, as to reproduce the wild-type lipase.

The term "synthetic sequence" or a variation thereof means a sequence that has been prepared by in vitro chemical or enzymatic synthesis. It includes, but is not limited to, sequences made with optimal codon usage for host organisms. The term applies to a synthetic microbial lipase or to a synthetic DNA sequence.

The term "isolated sequence" or a variation thereof means a sequence which is at least substantially free from at least one other component with which the sequence is naturally associated in nature and as found in nature. In alternative, an "isolated sequence" can also mean a sequence removed from its native environment. For example, sequences which have been recombinantly produced in a host organism are considered isolated for the purpose of this invention as are native or recombinant sequences which have been substantially purified by any suitable technique as such, for example, a purification method. Purification methods are well known in the art. The term applies to an isolated microbial lipase or to an isolated DNA sequence.

The term "recombinant sequence" or a variation thereof means a sequence that has been prepared using recombinant DNA techniques, which are within the capabilities of a person skilled in the art and are explained in literature, for example, J. Sambrook, E. F. Fritsch, and T. Maniatis, 1989, Molecular Cloning: A Laboratory manual, 2 ^nd edition, books 1-3, Cold Spring Harbor Laboratory Press. The term applies to a recombinant microbial lipase or to a recombinant DNA sequence.

The term "mature protein sequence" used herein means a sequence having lipolytic activity that is in its final form following translation and any co- and/or post-translational cleavage events or modifications, such as N-terminal processing, C-terminal truncation, glycosylation, phosphorylation, among other events or modifications.

The term "expression vector" means a construct capable of in vivo or in vitro expression. The expression vector may be incorporated, in particular stably incorporated, into the genome of a suitable host organism.

The term "sequence identity" describes a quantitative measure of similarity between two amino acid sequences or two nucleotide sequences. For purposes of the present invention, the degree of sequence identity between two amino acid sequences is based on aligning both sequences with the blastp suite provided by the National center for Biotechnology Information (NCBI) on https://blast.ncbi.nlm.nih.gov applying standard parameter settings (Matrix: BLOSUM62, Gap Costs: Existence: 11 Extension :1, Conditional compositional score matrix adjustment) and subsequent quantification of identical amino acid pairs in identical positions over the aligned amino acid sequences.

The term "food product" refers to a kind of milk-based product intended to be used as food, including, but not limited to, cheese, milk, skimmed milk, acidified milk, butter milk, condensed milk, spread, margarine, yoghurt, ice cream, milk powder, butter, dulce de leche, among others.

The term "dairy product" is intended to include any food product made using milk or milk- based product, including, but not limited to, cheese, milk, skimmed milk, acidified milk, butter milk, condensed milk, spread, margarine, yoghurt, ice cream, milk powder, butter, dulce de leche, among others.

The term "cheese" or "cheese product" are used interchangeably. The term "cheese" is understood to encompass any cheese, including, but not limited to, hard cheeses such as Pecorino, Provolone, Parmesan, Grana Padano, Parmigiano Reggiano, Romano, Chester, Danbo, Manchego, Saint Paulin, Cheddar, Monterey, Colby, Edam, Gouda, Muenster, Swiss type, Gruyere, Emmental; curd-cheeses such as Feta cheese; pasta filata cheeses such as Mozzarella, and Queso fresco cheese; fresh cheese such as Ricotta, Cream cheese, Neufchatel or Cottage cheese; cream cheese, white mold cheese such as Brie and Camembert cheese, blue mold cheese such as Gorgonzola and Danish blue cheese; and processed cheese, enzyme-modified cheese (EMC) or cheese-like product.

The term "processed cheese" is preferably manufactured from cheese or cheese analogues by cooking and emulsifying the cheese, such as with emulsifying salts (e.g. phosphates and citrate). The process may further include the addition of spices/condiments.

The term "enzyme-modified cheese" or "EMC" is understood as cheese curd which has been treated with enzymes to produce a concentrated cheese flavor ingredient which may have approximately 15-30 times the flavor intensity of natural cheese. EMCs are available as pastes or dried to form powders and are used to give a cheese flavor note to products such as processed cheese or analogue cheese, cheese powders, soups, sauces, dips, crackers, salad dressings and in coatings for snack foods.

The term "cheese-like product" is understood as cheese-like products which contain fat, such as e.g. milk fat (e.g. cream or butter) or vegetable oil, as a part of the composition, and which further contain, as part of the composition, one or more non-milk constituents, such as e.g. a vegetable constituent (e.g. vegetable protein or vegetable oil). In the context of the present invention, a "cheese-like product" includes a non-dairy cheese, also known as vegan cheese, wherein the fat used to make the non-dairy cheese is vegetable oil or an emulsion such as water-in-oil emulsion, instead of milk fat.

The term "improvement factor (IF)" is defined as the ratio obtained when dividing the enzymatic specificity for the release of short chain fatty acids of a tested lipase by the enzymatic specificity for the release of short chain fatty acids of a control lipase, preferably a control microbial lipase or is defined as the ratio obtained when dividing the enzymatic specificity for the release of medium chain fatty acids of a tested lipase by the enzymatic specificity for the release of medium chain fatty acids of a control lipase, preferably a control microbial lipase. If the ratio is 1, then the tested lipase has an identical preference, or specificity, for short chain fatty acids as control sequence. If the ratio is lower than one, then the tested lipase has less preference, or specificity, for short chain fatty acids than the control lipase, preferably a control microbial lipase. If the ratio is higher than one, then the tested lipase has higher preference, or specificity, for short chain fatty acids than the control. The enzymatic specificity for short chain fatty acids is obtained by dividing the enzymatic activity for short chain fatty acids C4 or C6 by the enzymatic activity for long chain fatty acids C16-C18. The improvement factor (IF) may also be determined by the ratio obtained when dividing the enzymatic specificity for the release of long chain fatty acids of a tested lipase by the enzymatic specificity for the release of long chain fatty acids of a control lipase, preferably a control microbial lipase. If the ratio is 1, then the tested lipase has an identical preference, or specificity, for longer chain fatty acids as the control lipase, preferably a control microbial lipase. If the ratio is lower than one, then the tested lipase has less preference, or specificity, for long chain fatty acids than the control. If the ratio is higher than one, then the tested lipase has higher preference, or specificity, for long chain fatty acids than the control. The enzymatic specificity for long chain fatty acids is obtained by dividing the enzymatic activity for long chain fatty acids C16-C18 by the enzymatic activity for short chain fatty acids C4 or C ₆ -

The term "control lipase" or "control microbial lipase" or "control lipolytic enzyme" or "control microbial lipolytic enzyme" is a commercial microbial lipase from Rhizomucur miehei (Palatase®, Palatase® 20000 L, available from Novozymes A/S), and herein labelled as commercial microbial lipase or commercial microbial lipase A. Alternatively, other microbial lipases from Rhizomucur miehei can be used, for example SpicelT ^® MR available from Chr. Hansen.

The term "signal peptide" relates to an amino acid sequence fused to the N-terminus of the polypeptide chain of the enzyme that is recognized by the secretory pathway of the enzyme producing microbial organism to translocate the synthesized protein into the cellular membrane or secrete it out of the cell into the fermentation medium.

The term "propeptide" relates to a polypeptide chain fused to the N-terminus of the major peptide chain of an enzyme that may support folding of the synthesized protein and/or contribute to its stability. The propeptide is cleaved during maturation or activation of the enzyme. A propeptide acts as an N-terminal extension of protein, distinct from the signal sequence which is necessary for the transport of the protein into or through the membrane, or for its secretion into the extracellular medium. The presence of a propeptide sequence may lead to a stabilization of the expression of lipases and/or may prevent inactivation in vivo of the lipase.

Amino acids are herein indicated by their one letter code or by their three letter code, both of which are well known to a person skilled in the art.

In the context of the present invention, SEQ ID NO: 1-11 stands for SEQ ID NO: 1, SEQ ID NO: 2, SEQ ID NO: 3, SEQ ID NO: 4, SEQ ID NO: 5, SEQ ID NO: 6, SEQ ID NO: 7, SEQ ID NO: 8, SEQ ID NO: 9, SEQ ID NO: 10 and SEQ ID NO: 11.

The purpose of this invention is to provide a microbial wild-type lipase with a higher specificity towards the release of C ₄ - fatty acids and/or C ₆ -fatty acids, from a dairy composition comprising milk fat and/or other fat, if compared with the release of medium and/or long chain fatty acids, preferably if compared with the release of long-chain fatty acids, or a higher specificity towards the release of C^fatty acids and/or C ₆ -fatty acids, from a dairy composition comprising milk fat and/or other fat, if compared to the release of C^fatty acids and/or Oe- fatty acids of a commercial microbial lipase, without the need to generate any mutation (addition, deletion and/or substitution) in the lipase sequence. Thus, this invention relates to an improved (or alternative) microbial wild-type lipase with specificity towards short-chain fatty acids versus the prior microbial lipases. Therefore, the lipases herein disclosed may be obtained from microorganisms that produce the lipase naturally. In this case, said lipase is a wild-type lipase.

The microbial lipases wherein disclosed (SEQ ID NO: 1-11) may be used to replace the microbial lipases currently available on the market.

The microbial lipases (SEQ ID NO: 1-11) herein disclosed were independently expressed as follows. Pichia pastoris was used as a host for lipase expression. Pichia pastoris was grown on YPD agar plates (Invitrogen) under selective conditions (100 pg/mL Zeocin) at 30°C for 16h. Seed fermentation was performed by inoculating 3 mL YPD liquid medium (Invitrogen) including 100 pg/mL Zeocin with a single colony from the respective YPD agar plates, followed by incubation at 30°C and 250 rpm agitation for 16h. Main fermentation was performed in 4 mL total volume by diluting seed fermentations with BMGY medium (Invitrogen) including 100 pg/mL Zeocin to an Oϋboo of 0.2, followed by incubation at 30°C and 225 rpm agitation for 3 days in 24-well culture plates. Main fermentation samples were centrifuged to precipitate expression host cells and the supernatant was sterile filtered at 0.2 pm. The filtrate was used directly for lipase enzymatic activity characterization without further treatment. The activity was determined in tri butyrin/agarose emulsion, for example as described below for Example 2 or by IDF method. In particular, the IDF method was used for dosing in Examples 3-6.

EXAMPLE 2 - ENZYMATIC ACTIVITY ON TRIACYLGLYCEROLS (TAGl SUBSTRATES

The enzymatic activity of each microbial lipase herein disclosed (SEQ ID NO: 1-11) towards short chain fatty acids (C4, substrate tributyrin), as well as long chain fatty acids (Ci ₆ and Cis, substrate olive oil), in 96-well plate assays, was performed as follows below. The same procedure (of determining the enzymatic activity towards short chain fatty acids (C4, substrate tributyrin)) and long chain fatty acids (Ci ₆ and Cis, substrate olive oil), in 96-well plate assays) was also conducted for a commercial microbial lipase from Rhizomucour miehei (Palatase®, Palatase® 20000 L, >20,000 U/g available from Novozymes A/S). The commercial microbial lipase from Rhizomucour miehei is herein labelled as commercial microbial lipase A.

Enzymatic activity for short chain fatty acids in plate: a tributyrin/agarose emulsion was generated by dissolving 1.4% low-melting agarose in 250 mM sodium acetate buffer pH 5.25 including 40 mM CaCh, addition of 1% (v/v) tributyrin to the solubilized agarose at 60°C, and subsequent emulsification for 2 min using an IKA T25 Ultra-Turrax emulsifier at speed 13.5. A total volume of 50 pL emulsion was transferred to each well of a transparent 96-well assay plate and allowed to solidify at room temperature. Lipase reaction was started by adding 20 pL enzyme on top of the emulsion layer, in particular wherein 20 pL enzyme correspond to 20 pL of filtrate obtained from Example 1. Clearance of turbidity of the emulsion by enzymatic hydrolysis of substrate tributyrin was followed by measuring absorbance at 600 nm in a plate reader. Each assay was calibrated with various dilutions of commercial microbial lipase A with known enzymatic activity.

Enzymatic activity for long chain fatty acids in plate: an olive oil/agarose emulsion was generated by dissolving 1.4% low-melting agarose in 250 mM sodium acetate buffer pH 5.25 including 40 mM CaCh, addition of 2.5% (v/v) olive oil and 0.001% rhodamine B (w/v) to the solubilized agarose at 60°C, and subsequent emulsification for 2 min using an IKA T25 Ultra- Turrax emulsifier at speed 13.5. A total volume of 150 pL emulsion was transferred to each well of a non-transparent black 96-well assay plate and allowed to solidify at room temperature. Lipase reaction was started by adding 30 pL enzyme on top of the emulsion layer, in particular wherein 30 pL enzyme correspond to 30 pL of filtrate obtained from Example 1. Binding of rhodamine B to long chain fatty acids released by enzymatic hydrolysis of substrate olive oil was followed by measuring fluorescence at 355 nm excitation and 590 nm emission in a plate reader. Each assay was calibrated with various dilutions of commercial microbial lipase A with known enzymatic activity.

Short chain fatty acid specificity C4/C16-C18 was determined, for each microbial lipase herein disclosed, by calculating the ratio of hydrolytic activities on substrate tributyrin (C4) and olive oil (C16-C18).

The ratio C /Ci ₆ -Ci ₈ of each lipase (SEQ ID NO: 1, SEQ ID NO: 2, SEQ ID NO: 3, SEQ ID NO: 4, SEQ ID NO: 5, SEQ ID NO: 6, SEQ ID NO: 7, SEQ ID NO: 8, SEQ ID NO: 9, SEQ ID NO: 10 and/or SEQ ID NO: 11) is normalized for the ratio C4/C16-C18 of the microbial commercial lipase (A) used. Table 1 shows that the microbial lipases herein disclosed (SEQ ID NO: 1-11) have a higher specificity for the short chain fatty acid butyric acid (C4) as compared to commercial microbial lipase A, in particular the microbial lipases of herein disclosed (SEQ ID NO: 1, SEQ ID NO: 2, SEQ ID NO: 3, SEQ ID NO: 4, SEQ ID NO: 5, SEQ ID NO: 6, SEQ ID NO: 7, SEQ ID NO: 8, SEQ ID NO: 9, SEQ ID NO: 10 and/or SEQ ID NO: 11) are 2-770 times more C^fatty acid specific than the commercial microbial lipase A.

Table 1. Short chain fatty acid specificity (CVCi ₆ -Cis) determined with TAG substrates tributyrin and olive oil of lipases with SEQ ID NO: 1, SEQ ID NO: 2, SEQ ID NO: 3, SEQ ID NO: 4, SEQ ID NO: 5, SEQ ID NO: 6, SEQ ID NO: 7, SEQ ID NO: 8, SEQ ID NO: 9, SEQ ID NO: 10, SEQ ID NO: 11 and commercial microbial lipase A and respective improvement factor (IF4).

EXAMPLE 3 - ENZYMATIC ACTIVITY IN CREAM The lipases herein disclosed (SEQ ID NO: 1, SEQ ID NO: 2, SEQ ID NO: 3, SEQ ID NO: 4, SEQ ID NO: 5, SEQ ID NO: 6, SEQ ID NO: 7, SEQ ID NO: 8, SEQ ID NO: 9, SEQ ID NO: 10 or SEQ ID NO: 11), were additionally analyzed for their enzymatic activity towards milk fat and the released free fatty acids were quantified (Table 2). The same procedure was conducted for a commercial microbial lipase (commercial microbial lipase A) from Rhizomucour miehei (Palatase®) available from Novozymes A/S. Lipase activity on milk fat in cream was carried out as follows. Fresh whipping cream (38% fat) and equal amounts of water were mixed by stirring for 30 min. Enzymatic reaction was started by adding 20 pL lipase (from a 4000 LFU/L stock solution) to 1 mL cream/water mix and proceeded at 37°C for 20 hours, in particular this dosage of enzyme applies both to the commercial microbial lipase A and to lipases of SEQ ID NO: 1-11. Subsequently, free fatty acids were extracted from the reaction and quantified by gas chromatography-mass spectrometry (GC-MS), using standard protocols in the art for quantifying fatty acids. Alternatively the disclosure of Jong C., de and Badings H.T. in J. High Resolution Chromatography. 13, 84-98 (1990) can also be used.

Obtained fatty acid quantities of lipase reactions were corrected for the respective quantities determined for a similar cream sample without added lipase.

Subsequently, specificity for butyric acid (C4:o), and caproic acid (C _6: o), caprylic acid (Cs:o) and capric acid (Cio _: o) and the respective improvement factors compared to commercial microbial lipase A were determined based on the obtained data from lipolysis in cream (Table 2). Short chain fatty acid specificities (CV Ci ₆ -Cis; _& / Ci ₆ -Cis) were obtained by calculating the ratio of the molar fraction of C4:o or C _6: o and the sum of molar fractions of Ci _6: o, Cis:o, C is _: 1 and Ci8 _: 2. Improvement factors IF4 and IF6 were calculated by dividing specificity values for C4 _: o and C _6: o by the respective values of commercial lipase A. Medium chain fatty acid specificities (Cs/ Ci ₆ -Cis; Cio/ Ci ₆ -Cis)were obtained by calculating the ratio of the molar fraction of Cs:o or Cio:o and the sum of molar fractions of Ci _6: o, Cis:o, Cis:i and Cis:2. Improvement factors IF8 and IF10 were calculated by dividing specificity values for Cs _: o and Cio _: o, respectively, by the respective values of commercial lipase A.

The ratio C4/C16-C18 of each lipolytic lipase is determined by diving C4:o by the sum of Ci6:o, Ci8:o, C is : 1 and Ci8:2 of the respective lipolytic lipase. The ratio C4/C16-C18 is indicative of the specificity of the respective lipase for the release of butyric acid (C4) from milk fat, relative to the release of fatty acids with chain lengths Ci ₆ - Cis-

The ratio C6/C16-C18 of each lipolytic lipase is determined by diving C6:o by the sum of Ci6:o, Ci8:o, C is : 1 and Ci8:2 of the respective lipolytic lipase. The ratio C ₆ /Ci ₆ -Cis is indicative of the specificity of the respective lipase for the release of caproic acid {Ce) from milk fat, relative to the release of fatty acids with chain lengths Ci ₆ - Cis-

The ratio Cs/Ci ₆ -Cis of each lipolytic lipase is determined by diving Cs:o by the sum of Ci _6: o, Ci8:o, C is : 1 and Ci8:2 of the respective lipolytic lipase. The ratio Cs/Ci ₆ -Cis is indicative of the specificity of the respective lipase for the release of caproic acid (Cs) from milk fat, relative to the release of fatty acids with chain lengths Ci ₆ - Cis-

The ratio C10/C16-C18 of each lipolytic lipase is determined by diving Cio:o by the sum of Ci6:o, Ci _8: o, C is : 1 and Ci8:2 of the respective lipolytic lipase. The ratio C10/C16-C18 is indicative of the specificity of the respective lipase for the release of caproic acid (Cio) from milk fat, relative to the release of fatty acids with chain lengths Ci ₆ - Cis-

Table 3. Short chain and medium chain fatty acid specificities (C ₄ /C ₁₆ -C ₁₈ , Ce/Cie-Cis, Cs/Ci ₆ - Ci ₈ , C ₁₀ /C ₁₆ -C ₁₈ ) and improvement factors (IF4, IF6, IF8, IF10) in cream by commercial microbial lipase A and SEQ ID NO: 1, SEQ ID NO: 2, SEQ ID NO: 3, SEQ ID NO: 4, SEQ ID NO: 5, SEQ ID NO: 6, SEQ ID NO: 7, SEQ ID NO: 8, SEQ ID NO: 9, SEQ ID NO: 10 and SEQ ID NO: 11.

All the microbial lipolytic enzymes herein disclosed (SEQ ID NO: 1, SEQ ID NO: 2, SEQ ID NO: 3, SEQ ID NO: 4, SEQ ID NO: 5, SEQ ID NO: 6, SEQ ID NO: 7, SEQ ID NO: 8, SEQ ID NO: 9, SEQ ID NO: 10 and/or SEQ ID NO: 11) show an IF4 higher than 1, in cream, meaning they have a higher specificity for the short chain fatty acid butyric acid (C4 _: o) compared to commercial lipase A (Table 3) and can, therefore, be successfully used in a process for producing a food product wherein the presence of short chain fatty acid butyric acid (C _4: o) is needed and desired, such as for reducing soapiness and increase in butyric flavors in a food product.

Microbial lipolytic enzymes with SEQ ID NO: 1-7 and SEQ ID NO: 9-11 show an IF6 higher, than 1 in cream, meaning they have a higher specificity for the short chain fatty acid caproic acid (C _6: o) compared to commercial lipase A.

Microbial lipolytic enzymes with SEQ ID NO: 1-6 and SEQ ID NO: 8-11 show an IF8 higher, than 1 in cream, meaning they have a higher specificity for the medium chain fatty acid caprylic acid (Cs:o) compared to commercial lipase A .

Microbial lipolytic enzymes with SEQ ID NO: 1-3, SEQ ID NO: 6-8 and SEQ ID NO: 10-11 show an IF10 higher, than 1 in cream, meaning they have a higher specificity for the medium chain fatty acid capric acid (Cio _: o) compared to commercial lipase A.

Microbial lipolytic enzyme with SEQ ID NO: 1 has a higher specificity for C _4: o than for any other fatty acid, in cream. The same applies for microbial lipolytic enzymes having SEQ ID NO: 3 or SEQ ID NO: 9 (Table 2).

EXAMPLE 4 - ENZYMATIC ACTIVITY IN CHEESE

SEQ ID NO: 1 was further tested in cheese, in particular in Feta cheese and in Provolone cheese (Table 4). Example 4 was carried out with an identical dosage of enzyme (commercial microbial lipase A and SEQ ID NO: 1), in particular with a dosage of about 1.7 LFU/L of enzyme per liter of milk was used for the production of Feta cheese and between 5-10x for the Provolone cheese. The dosage was determined by the IDF method.

Microbial lipase SEQ ID NO: 1 was added during the cheese making process. The cheese making process of, for example Feta cheese or Provolone cheese, is well known in the art and to the skilled person. Subsequently, free fatty acids were extracted from cheeses after 1 month of ripening and quantified by GC-MS or as disclosed in Example 3. Obtained fatty acid quantities of lipase reactions were corrected for the respective quantities determined for a similar cheese without added lipase. Short chain fatty acid specificities were obtained by calculating the ratio of the molar fraction of C _4: o or C _6: o and the sum of molar fractions of Ci _6: o, Ci _8: o, Ci _8:i and Ci _8:2 - Improvement factors IF4 and IF6 were calculated by dividing specificity values for C _4: o and Oe _: o by the respective values of commercial lipase A. Table 4. Molar fractions of fatty acids released in Feta cheese and Provolone cheese by commercial microbial lipase A and SEQ ID NO: 1, after 1-month of ripening, as well as short chain fatty acid specificities (C /C ₁ 6-C ₁ 8 and Ce/Cie-Cia) and improvement factors (IF4 and IF6).

SEQ ID NO: 1 has a higher specificity for C _4: o-fatty acids than commercial microbial lipase A, in Feta cheese and in Provolone cheese, and a higher specificity for C _4: o-fatty acids than for any other fatty acid, both Feta cheese and Provolone cheese, which is in line with the results obtained in cream (Example 3). Further, SEQ ID NO: 1 also has a higher specificity for C6 _: o- fatty acids than commercial microbial lipase A, in Feta cheese and in Provolone cheese, which is also in line with the results obtained in cream (Example 3).

SEQ ID NO: 1 also shows a lower specificity for medium to long chain fatty acids such as Cs _: o, Cio:o,Ci4:o,Ci6:o,Ci8:o,Ci8:i or Ci8:2 fatty acids when compared to commercial microbial lipase A in Feta cheese. Furthermore, SEQ ID NO: 1 also shows a lower specificity for medium to long chain fatty acids such as Cs:o,Cio:o,Ci2:o,Ci4:o,Ci6:o,Ci8:o,Ci8:i or Ci8:2 fatty acids when compared to commercial microbial lipase A in Provolone cheese. These results are in line with the results obtained in cream (Example 3). Thus, a cheese produced using a microbial lipase comprising SEQ ID NO: 1 or wherein the microbial lipase is microbial lipase of SEQ ID NO: 1 is less soapy and more butyric than a cheese produced with a known microbial lipase. Identical results are expected for SEQ ID NO: 2, SEQ ID NO: 3, SEQ ID NO: 4, SEQ ID NO: 5, SEQ ID NO: 6, SEQ ID NO: 7, SEQ ID NO: 8, SEQ ID NO: 9, SEQ ID NO: 10 and/or SEQ ID NO: 11.

Identical results are also expected for other types of cheese, such as Pecorino, Parmesan, Grana Padano, Parmigiano Reggiano, Romano, Chester, Danbo, Manchego, Saint Paulin, Cheddar, Monterey, Colby, Edam, Gouda, Muenster, Swiss type, Gruyere, Emmental; pasta filata cheeses such as Mozzarella, and Queso fresco cheese; fresh cheese such as Ricotta, Cream cheese, Neufchatel or Cottage cheese; cream cheese, white mold cheese such as Brie and Camembert cheese, blue mold cheese such as Gorgonzola and Danish blue cheese; processed cheese, cheese-like product, or an enzyme-modified cheese. The microbial lipases herein disclosed are responsible for an increase in the C^fatty acid specificity in comparison with the prior art microbial lipases, thus leading to a reduced soapiness of cheese and an increase in the butyric flavor of cheese.

EXAMPLE 5 - SENSORIAL EVALUATION A sensorial evaluation of cheese, in particular in Feta cheese aged 3-months, was also performed by rating the taste according to sensational parameters butyric and soapy on a scale from 1 (none) to 6 (intense). The Feta cheese was produced using identical conditions using a commercial A or SEQ ID NO: 1 or SEQ ID NO: 3 or SEQ ID NO: 5. The amount or dosage of enzyme (commercial microbial lipase A, SEQ ID NO: 1 or SEQ ID NO: 3 or SEQ ID NO: 5) used was 1.7 LFU/L of milk determined by the IDF method (Table 5).

Table 5. Sensorial evaluation carried out with Feta cheese aged 3-months using of commercial microbial lipase A, SEQ ID NO: 1, SEQ ID NO: 3 and SEQ ID NO: 5.

Table 5 shows a reduction of soapiness in Feta cheese, aged 3-months when SEQ ID NO: 1 or 3 or 5 is used when compared with commercial lipase A, while simultaneously an increase in the butyric flavor is observed for the same samples.

EXAMPLE 6 - ENZYMATIC ACTIVITY IN CHEESE

SEQ ID NO: 1, 2, 3, 6, 8, 10 and 11 were further tested in cheese, in particular in Feta cheese. Example 6 was carried out with an identical dosage of enzyme (the commercial microbial lipase A and SEQ ID NO: 1, 2, 3, 6, 8, 10 and 11), in particular the a dosage of enzyme was of about 2.3 LFU/L of milk, determined by the IDF method, for the production of Feta cheese.

Microbial lipases SEQ ID NO: 1, 2, 3, 6, 8, 10 and 11 were individually added during the cheese making process. Subsequently, free fatty acids were extracted from cheeses after 1- month (Table 6) and 2-months (Table 8) of ripening and quantified by GC-MS or as disclosed in Example 3. Obtained fatty acid quantities of lipase reactions were corrected for the respective quantities determined for a similar cheese without added lipase. Short- and medium-chain fatty acid specificities were obtained by calculating the ratio of the molar fraction of C4:o,C6:o,Cs:o or Cio:o and the sum of molar fractions of Ci6:o,Ci6:i,Ci8:o,Ci8:i, Ci8:2 and Cis:3 (Tables 7 and 9). Improvement factors IF4, IF6, IF8 and IF10 were calculated by dividing specificity values for C4:o,Oe:oCs:o or Cio:o by the respective values of commercial lipase A (Tables 7 and 9).

Table 6. Molar fractions of fatty acids released in Feta cheese by commercial microbial lipase A and SEQ ID NO: 1, 2, 3, 6, 10 and 11, after 1-monthh of ripening. All lipases were dosage at 2.3 LFU/L. Table 7. Short- and medium-chain fatty acid specificities (C ₄ /C ₁₆ -C ₁₈ , Ce/Cie-Cia, Ca/Cie-Cia, C ₁₀ /C ₁₆ -C ₁₈ ) and improvement factors (IF4, IF6, IF8, IF10) in Feta cheese by commercial microbial lipase A and SEQ ID NO: 1, 2, 3, 6, 10 and 11, after 1-monthh of ripening. All lipases were dosage at 2.3 LFU/L.

All the tested microbial lipolytic enzymes show an IF4 higher than 1, in Feta cheese, after 1- month of ripening. Thus, the tested enzymes have a higher specificity for the short chain fatty acid butyric acid (C4 _: o) compared to commercial lipase A (Table 7) and can, therefore, be successfully used in a process for producing a food product wherein the presence of short chain fatty acid butyric acid (C4 _: o) is needed and desired, such as for reducing soapiness and increase in butyric flavors in a food product. This observation, of an IF higher than 1 for the tested lipases, is in line with the results of Example 3, where data was obtained in cream. Further, specifically for SEQ ID NO: 1, this observation is also in line with the results of Example 4. Further, these enzymes show an IF6, IF8 and IF10 higher than 1, in Feta cheese, after 1- month of ripening, meaning they have a higher specificity for the short chain fatty acid caproic acid (C _6: o) and for medium chain fatty acid caprylic acid (Cs:o) and capric acid (Cio:o) compared to commercial lipase A, with the exception of SEQ ID NO: 2 which has a IF10 below 1. The results obtained for these sequences (SEQ ID NO: 1, 2, 3, 6, 10 and 11) and their specificity for C _6: o-fatty acids, Cs _: o-fatty acids and Cio _: o-fatty acids are essentially in line with the results obtained in cream (Example 3). In conclusion, the results obtained in cheese, after 1-month of ripening (Example 4 and 6) are in line with the results obtained in cream (Example 3), showing that the results obtained in cream can be used to plausibly extrapolate the behavior of the non-tested sequences from cream to cheese. Table 8. Molar fractions of fatty acids released in Feta cheese by commercial microbial lipase A and SEQ ID NO: 1, 2, 3, 6, 8, 10 and 11, after 2-monthh of ripening. All lipases were dosage at 2.3 LFU/L.

Table 9. Short- and medium-chain fatty acid specificities (C ₄ /C ₁₆ -C ₁₈ , Ce/Cie-Cis, Cs/Ci ₆ -Cis, C ₁₀ /C ₁₆ -C ₁₈ ) and improvement factors (IF4, IF6, IF8, IF10) in Feta cheese by commercial microbial lipase A and SEQ ID NO: 1, 2, 3, 6, 8, 10 and 11, after 2-monthh of ripening. All lipases were dosage at 2.3 LFU/L.

All the tested microbial lipolytic enzymes show an IF4 higher than 1, in Feta cheese, after 2- month of ripening. Thus, the tested enzymes have a higher specificity for the short chain fatty acid butyric acid (C4 _: o) compared to commercial lipase A (Table 7) and can, therefore, be successfully used in a process for producing a food product wherein the presence of short chain fatty acid butyric acid (C4 _: o) is needed and desired, such as for reducing soapiness and increase in butyric flavors in a food product.

Microbial lipolytic enzymes with SEQ ID NO: 1, 2, 3, 6, 8, 10 and 11 show an IF6 and IF8 higher than 1, meaning they have a higher specificity for the short chain fatty acid caproic acid (C _6: o) and for medium chain fatty acid caprylic acid (Cs _: o) compared to commercial lipase A.

The tested enzymes, with the exception of SEQ ID NO: 3, also shown an IF10 higher than 1, and have, therefore, a higher specificity for medium chain fatty capric acid (Cio _: o) compared to commercial lipase A. Further and as previously mentioned this invention relates to flavor enhancement but also with shortening of the ripening times for ripened cheeses. The comparison between free fatty acid profiles after 1-month or 2-months of ripening shows that it is possible to successfully reduce ripening time from 2-months (or more) to 1-month (or less), while the cheese still presents the desired short-chain fatty acid profile.

Identical results to those disclosed in Example 6 are also expected for other types of cheese, such as Pecorino, Parmesan, Grana Padano, Parmigiano Reggiano, Romano, Chester, Danbo, Manchego, Saint Paulin, Cheddar, Monterey, Colby, Edam, Gouda, Muenster, Swiss type, Gruyere, Emmental; pasta filata cheeses such as Mozzarella, and Queso fresco cheese; fresh cheese such as Ricotta, Cream cheese, Neufchatel or Cottage cheese; cream cheese, white mold cheese such as Brie and Camembert cheese, blue mold cheese such as Gorgonzola and Danish blue cheese; processed cheese, cheese-like product, or an enzyme-modified cheese.

In conclusion, the present invention discloses microbial wild-type lipases with a higher specificity for short chain fatty acids, specially C^fatty acid, than the known prior art microbial lipases, leading to a reduction in soapiness and an increase in butyric flavors of a food product such as cheese. Therefore, this invention provides microbial wild-type lipases which fulfill the vegetarian and/or kosher requirements, while simultaneously showing higher specificity for short chain fatty acids, specially C^fatty acid and lower specificity for medium to long chain fatty acids from milk fat and/or other fat, specially showing lower specificity for long chain fatty acids from milk fat and/or other fat, thereby avoiding an extremely unpleasant soapy taste in a food product, like cheese.
