FIELD OF THE INVENTION

The present invention also relates to new polypeptides of fungal origin having superoxide dismutase activity and to animal feed additive or animal feed comprising superoxide dismutase of fungal origin. The present invention relates to the use of polypeptides of fungal origin having superoxide dismutase activity for

• • improving one or more performance parameters, wherein the one or more performance parameters is selected from the group consisting of the European Production Efficiency Factor (EPEF), Feed Conversion Ratio (FCR), Growth Rate (GR), Body Weight Gain (WG), Mortality Rate (MR) and Flock Uniformity (FU),
  • improving or enhancing immune response and/or reducing inflammation and/or for the modulation of the gut flora in an animal, and
  • reducing or eliminating the use of antibiotics administered to animal feed.

BACKGROUND OF THE INVENTION

Superoxide dismutase (SOD, EC 1.15.1.1) is an enzyme that alternately catalyzes the dismutation (or partitioning) of the superoxide (O₂⁻) radical into either ordinary molecular oxygen (O₂) or hydrogen peroxide (H₂O₂). Superoxide is produced as a by-product of oxygen metabolism and, if not regulated, causes many types of cell damage. Thus, SOD is an important antioxidant defense in nearly all living cells exposed to oxygen. SODs are used in the pharmaceutical, cosmetic, food, and environmental protection industries due to their excellent antioxidant properties. Historically, SODs were isolated from animal or plant sources, but the microbial sources organisms can be easily induced and cultivated on a large scale

SODs naturally occur in many organisms such as plants, insects, birds, reptiles and mammals. Four types of SODs have been reported according to their metal cofactors: manganese SOD (Mn-SOD), iron SOD (Fe-SOD), copper/zinc SOD (Cu/Zn-SOD), and nickel SOD (Ni-SOD)₂.

Commercially available mammalian (bovine) SOD (Sigma), a Cu/Zn SOD, although having a high activity at neutral pH or at its optimal pH of 7.8, was found to lose 65% of its activity under gastric stability studies. According to its datasheet, its pH range is 7.6-10.5. Commerically available bacterial (from E. coli) Mn-SOD (S5639 from Sigma) was found to lose 57% of its activity under gastric stability studies.

Surprisingly, the inventors of the present invention found that fungal SODs are gastric stable and provide beneficial effects when used in an animal feed or animal feed additive, alone or in combination with a catalase, to improve one or more performance parameters, enhance immune response and reduce inflammation in an animal and thus lead to many advantages such as improving animal health and/or animal performance, and/or reducing feeding cost.

SUMMARY OF THE INVENTION

The invention is directed, at least in part, to novel polypeptides of fungal origin having superoxide dismutase activity and directed to an animal feed additive comprising a polypeptide of fungal origin having superoxide dismutase activity. A further aspect is directed to an animal feed additive comprising at least one and no more than two enzyme classes, wherein the at least one enzyme class is a superoxide dismutase of fungal origin and the optional second enzyme class is a catalase.

DETAILED DESCRIPTION OF THE INVENTION

The invention is related one or more polypeptides having superoxide dismutase activity in animal feed wherein the superoxide dismutase is of fungal origin.

Definitions

Animal: The term “animal” refers to any animal except humans. Examples of animals are monogastric animals, including but not limited to pigs or swine (including, but not limited to, piglets, growing pigs, and sows); poultry such as turkeys, ducks, quail, guinea fowl, geese, pigeons (including squabs) and chicken (including but not limited to broiler chickens (referred to herein as broiles), chicks, layer hens (referred to herein as layers)); pets such as cats and dogs; horses (including but not limited to hotbloods, coldbloods and warm bloods) crustaceans (including but not limited to shrimps and prawns) and fish (including but not limited to amberjack, arapaima, barb, bass, bluefish, bocachico, bream, bullhead, cachama, carp, catfish, catla, chanos, char, cichlid, cobia, cod, crappie, dorada, drum, eel, goby, goldfish, gourami, grouper, guapote, halibut, java, labeo, lai, loach, mackerel, milkfish, mojarra, mudfish, mullet, paco, pearlspot, pejerrey, perch, pike, pompano, roach, salmon, sampa, sauger, sea bass, seabream, shiner, sleeper, snakehead, snapper, snook, sole, spinefoot, sturgeon, sunfish, sweetfish, tench, terror, tilapia, trout, tuna, turbot, vendace, walleye and whitefish).

Animal feed: The term “animal feed” refers to any compound, preparation, or mixture suitable for, or intended for intake by an animal. Animal feed for a monogastric animal typically comprises concentrates as well as vitamins, minerals, enzymes, direct fed microbial, amino acids and/or other feed ingredients (such as in a premix) whereas animal feed for ruminants generally comprises forage (including roughage and silage) and may further comprise concentrates as well as vitamins, minerals, enzymes direct fed microbial, amino acid and/or other feed ingredients (such as in a premix).

Concentrates: The term “concentrates” means feed with high protein and energy concentrations, such as fish meal, molasses, oligosaccharides, sorghum, seeds and grains (either whole or prepared by crushing, milling, etc. from e.g. corn, oats, rye, barley, wheat), oilseed press cake (e.g. from cottonseed, safflower, sunflower, soybean (such as soybean meal), rapeseed/canola, peanut or groundnut), palm kernel cake, yeast derived material and distillers grains (such as wet distillers grains (WDS) and dried distillers grains with solubles (DDGS)).

Feed efficiency: The term “feed efficiency” means the amount of weight gain per unit of feed when the animal is fed ad-libitum or a specified amount of food during a period of time. By “increased feed efficiency” it is meant that the use of a feed additive composition according the present invention in feed results in an increased weight gain per unit of feed intake compared with an animal fed without said feed additive composition being present.

Feed Conversion Ratio (FCR): FCR is a measure of an animal's efficiency in converting feed mass into increases of the desired output. Animals raised for meat such as swine, poultry and fish the output is the mass gained by the animal. Specifically, FCR is calculated as feed intake divided by weight gain, all over a specified period. Improvement in FCR means reduction of the FCR value. An FCR improvement of 2% means that the FCR was reduced by 2%.

Feed Premix: The incorporation of the composition of feed additives as exemplified herein above to animal feeds, for example poultry feeds, is in practice carried out using a concentrate or a premix. A premix designates a preferably uniform mixture of one or more microingredients with diluent and/or carrier. Premixes are used to facilitate uniform dispersion of micro-ingredients in a larger mix. A premix according to the invention can be added to feed ingredients or to the drinking water as solids (for example as water soluble powder) or liquids.

European Production Efficiency Factor (EPEF): The European Production Efficiency Factor is a way of comparing the performance of animals. This single-figure facilitates comparison of performance within and among farms and can be used to assess environmental, climatic and animal management variables. The EPEF is calculated as [(liveability (%)×Liveweight (kg))/(Age at depletion (days)×FCR)]×100, wherein livability is the percentage of animals alive at slaughter, Liveweight is the average weight of the animals at slaughter, age of depletion is the age of the animals at slaughter and FCR is the feed conversion ratio at slaughter.

Forage: The term “forage” as defined herein also includes roughage. Forage is fresh plant material such as hay and silage from forage plants, grass and other forage plants, seaweed, sprouted grains and legumes, or any combination thereof. Examples of forage plants are Alfalfa (lucerne), birdsfoot trefoil, brassica (e.g. kale, rapeseed (canola), rutabaga (swede), turnip), clover (e.g. alsike clover, red clover, subterranean clover, white clover), grass (e.g.

Bermuda grass, brome, false oat grass, fescue, heath grass, meadow grasses, orchard grass, ryegrass, Timothy-grass), corn (maize), millet, barley, oats, rye, sorghum, soybeans and wheat and vegetables such as beets. Forage further includes crop residues from grain production (such as corn stover; straw from wheat, barley, oat, rye and other grains); residues from vegetables like beet tops; residues from oilseed production like stems and leaves form soy beans, rapeseed and other legumes; and fractions from the refining of grains for animal or human consumption or from fuel production or other industries.

Fragment: The term “fragment” means a polypeptide or a catalytic domain having one or more (e.g., several) amino acids absent from the amino and/or carboxyl terminus of a mature polypeptide or domain; wherein the fragment has SOD activity.several) amino acids absent from the amino and/or carboxyl terminus of a mature polypeptide or domain; wherein the fragment has SOD activity.

Physical determination of the mature N terminus of SODs was done with Mass Spectrometry. Samples were diluted to 0.1 mg/ml in water. If they were to be deglycosylated before analysis, the samples were suspended in 50 mM Ammonium acetate buffer pH 5.5. The samples are then placed in an Ultimate 3000 UHPLC system (Thermo Scientific) at 8 degrees C. and run over an Advance Bio-RP desalting column (Agilent) The solvents used were A: LC/MS grade water with 0.1% formic acid, solvent: B 95% acetonitrile with 0.1% formic acid. The gradient was 5-80% B over 5 minutes. Post column the protein eluent was analyzed in a Bruker Maxis II mass spectrometer (Bremen Germany) and the resulting trace was analyzed by the supplied Bruker data analysis software. The deconvoluted spectrum was then compared to the calculated molecular weight with the expected N and C terminals using GPMAW (General Protein/Mass Analysis for Windows) software version 12.20. If the values match within 1 Dalton, a match was concluded.

Nutritional Stress: In pigs, poultry and other animals, symptoms of nutritional stress include impaired growth, immune suppression, reduced gut health, reduced gut integrity, shift in gut microflora and vomiting. In poultry, further symptoms include decreased egg production, decreased hatchability, gizzaed lesions, increased suspectibility to necrotic enteritis.

Obtained or obtainable from: The term “obtained or obtainable from” means that the polypeptide may be found in an organism from a specific taxonomic rank. In one embodiment, the polypeptide is obtained or obtainable from the kingdom Fungi, wherein the term kingdom is the taxonomic rank. In a preferred embodiment, the polypeptide is obtained or obtainable from the phylum Ascomycota, wherein the term phylum is the taxonomic rank. In another preferred embodiment, the polypeptide is obtained or obtainable from the subphylum Pezizomycotina, wherein the term subphylum is the taxonomic rank. In another preferred embodiment, the polypeptide is obtained or obtainable from the class Eurotiomycetes, wherein the term class is the taxonomic rank.

If the taxonomic rank of a polypeptide is not known, it can easily be determined by a person skilled in the art by performing a BLASTP search of the polypeptide (using e.g. the National Center for Biotechnology Information (NCIB) website http://www.ncbi.nlm.nih.gov/) and comparing it to the closest homologues. The skilled person can also compare the sequence to those of the application as filed. An unknown polypeptide which is a fragment of a known polypeptide is considered to be of the same taxonomic species. An unknown natural polypeptide or artificial variant which comprises a substitution, deletion and/or insertion in up to 10 positions is considered to be from the same taxonomic species as the known polypeptide.

Oxidative Stress: The term “oxidative stress” is intended to mean an imbalance between oxidants and reductants (antioxidants) at the cellular or individual level. Oxidative damage is one result of such an imbalance and includes oxidative modification of cellular macromolecules, cell death by apoptosis or necrosis, as well as structural tissue damage by means of reactive oxygen and nitrogen species (ROS, RNS).

Roughage: The term “roughage” means dry plant material with high levels of fiber, such as fiber, bran, husks from seeds and grains and crop residues (such as stover, copra, straw, chaff, sugar beet waste).

Secreted Enzyme: A secreted enzyme is an exoenzyme, or extracellular enzyme, in that is an enzyme that is secreted by a cell and functions outside that cell.

Sequence identity: The relatedness between two amino acid sequences or between two nucleotide sequences is described by the parameter “sequence identity”.

For purposes of the present invention, the sequence identity between two amino acid sequences is determined using the Needleman-Wunsch algorithm (Needleman and Wunsch, 1970, J. Mol. Biol. 48: 443-453) as implemented in the Needle program of the EMBOSS package (EMBOSS: The European Molecular Biology Open Software Suite, Rice et al., 2000, Trends Genet. 16: 276-277), preferably version 5.0.0 or later. The parameters used are gap open penalty of 10, gap extension penalty of 0.5, and the EBLOSUM62 (EMBOSS version of BLOSUM62) substitution matrix. The output of Needle labeled “longest identity” (obtained using the −nobrief option) is used as the percent identity and is calculated as follows:

(Identical Residues×100)/(Length of Alignment−Total Number of Gaps in Alignment)

Substantially pure polypeptide: The term “substantially pure polypeptide” means a preparation that contains at most 10%, at most 8%, at most 6%, at most 5%, at most 4%, at most 3%, at most 2%, at most 1%, and at most 0.5% by weight of other polypeptide material with which it is natively or recombinantly associated. Preferably, the polypeptide is at least 92% pure, e.g., at least 94% pure, at least 95% pure, at least 96% pure, at least 97% pure, at least 98% pure, at least 99%, at least 99.5% pure, and 100% pure by weight of the total polypeptide material present in the preparation. The polypeptides of the present invention are preferably in a substantially pure form. This can be accomplished, for example, by preparing the polypeptide by well known recombinant methods or by classical purification methods.

Tm: The term Tm, as used in the Examples refers to the temperature at which 50% of the protein molecules are unfolded and 50% of the protein molecules are folded.

Variant: The term “variant” means a polypeptide having SOD activity comprising an alteration, i.e., a substitution, insertion, and/or deletion, of one or more (several) amino acid residues at one or more (e.g., several) positions. A substitution means replacement of the amino acid occupying a position with a different amino acid; a deletion means removal of the amino acid occupying a position; and an insertion means adding 1, 2, or 3 amino acids adjacent to and immediately following the amino acid occupying the position.

In one aspect, a SOD variant may comprise from 1 to 10 alterations, i.e. 1, 2, 3, 4, 5, 6, 7, 8, 9 or 10 alterations and have at least 20%, e.g., at least 40%, at least 50%, at least 60%, at least 70%, at least 80%, at least 90%, at least 95%, or at least 100% of the SOD activity of the parent SOD, such as SEQ ID NO: 1 to 5.

Nutrient: The term “nutrient” in the present invention means components or elements contained in dietary feed for an animal, including water-soluble ingredients, fat-soluble ingredients and others. The example of water-soluble ingredients includes but is not limited to carbohydrates such as saccharides including glucose, fructose, galactose and starch; minerals such as calcium, magnesium, zinc, phosphorus, potassium, sodium and sulfur; nitrogen source such as amino acids and proteins, vitamins such as vitamin B1, vitamin B2, vitamin B3, vitamin B6, folic acid, vitamin B12, biotin and phatothenic acid. The example of the fat-soluble ingredients includes but is not limited to fats such as fat acids including saturated fatty acids (SFA); mono-unsaturated fatty acids (MUFA) and poly-unsaturated fatty acids (PUFA), fibre, vitamins such as vitamin A, vitamin E and vitamin K.

As the SODs defined above are novel enzymes, the invention further relates to an isolated polypeptide as defined herein having superoxide dismutase activity.

The amino acid changes in the sequences disclosed above may be of a minor nature, that is conservative amino acid substitutions or insertions that do not significantly affect the folding and/or activity of the protein; small deletions, typically of 1-30 amino acids; small amino- or carboxyl-terminal extensions, such as an amino-terminal methionine residue; a small linker peptide of up to 20-25 residues; or a small extension that facilitates purification by changing net charge or another function, such as a poly-histidine tract, an antigenic epitope or a binding domain.

Examples of conservative substitutions are within the groups of basic amino acids (arginine, lysine and histidine), acidic amino acids (glutamic acid and aspartic acid), polar amino acids (glutamine and asparagine), hydrophobic amino acids (leucine, isoleucine and valine), aromatic amino acids (phenylalanine, tryptophan and tyrosine), and small amino acids (glycine, alanine, serine, threonine and methionine). Amino acid substitutions that do not generally alter specific activity are known in the art and are described, for example, by H. Neurath and R. L. Hill, 1979, In, The Proteins, Academic Press, New York. Common substitutions are Ala/Ser, Val/Ile, Asp/Glu, Thr/Ser, Ala/Gly, Ala/Thr, Ser/Asn, Ala/Val, Ser/Gly, Tyr/Phe, Ala/Pro, Lys/Arg, Asp/Asn, Leu/Ile, Leu/Val, Ala/Glu, and Asp/Gly.

Essential amino acids in the polypeptide can be identified according to procedures known in the art, such as site-directed mutagenesis or alanine-scanning mutagenesis (Cunningham and Wells, 1989, Science 244: 1081-1085). In the latter technique, single alanine mutations are introduced at every residue in the molecule, and the resultant mutant molecules are tested for SOD activity to identify amino acid residues that are critical to the activity of the molecule. See also, Hilton et al., 1996, J. Biol. Chem. 271: 4699-4708. The active site of the enzyme or other biological interaction can also be determined by physical analysis of structure, as determined by such techniques as nuclear magnetic resonance, crystallography, electron diffraction, or photoaffinity labelling, in conjunction with mutation of putative contact site amino acids. See, for example, de Vos et al., 1992, Science 255: 306-312; Smith et al., 1992, J. Mol. Biol. 224: 899-904; Wlodaver et al., 1992, FEBS Lett. 309: 59-64. The identity of essential amino acids can also be inferred from an alignment with a related polypeptide.

Metals of Superoxide Dismutases

In an embodiment of the invention the polypeptide having superoxide dismutase activity is of fungal origin and is selected from the group consisting of a Cu-SOD, a Zn-SOD, a Cu/Zn-SOD, a Mn-SOD, and an Fe-SOD, more typically a Cu-SOD, a Zn-SOD, a Cu/Zn-SOD, a Mn-SOD, and an Fe-SOD, even more typically a Cu-SOD, a Zn-SOD, a Cu/Zn-SOD, or a Mn-SOD.

In a suitable embodiment of the invention the polypeptide having superoxide dismutase activity is of fungal origin and is selected from the group consisting of a Cu-SOD and a Cu/Zn-SOD.

The copper ion is involved in the catalysis of Cu-SODs whereas the zinc ion plays a structural role. The redox active copper catalyzes the disproportionation of superoxide anion to oxygen and hydrogen peroxide, whereas the zinc helps stabilize the protein and promotes pH independence of the reaction.

In one embodiment of the invention, the superoxide dismutase of fungal origin has an activity of at least 1000 U/mg at pH 7.8, such as at least 1500 U/mg, or at least 2000 U/mg, or at least 3000 U/mg, or at least 4000 U/mg, or at least 5000 U/mg, suitably as measured by the method described in Example 9.

Gastric Stability of Superoxide Dismutases

In a preferred embodiment, the SOD, given it is intended for use as an animal feed additive, is gastric stable, when measured according to the method described in Example 10. As can be seen from the table in Example 10, the commercially available superoxide dismutase from bovine erythrocytes and expressed in E. coli of sequence A:

retains only 26% of its activity upon gastric treatment in the presence of pepsin.

Two commercial SODs were tested as references: SOD-Mn, from E. coli Sigma S5639 with a activity of 10240 U/mg EP and only 26% activity left after gastric press for 30 min; and SOD-Cu/Zn from Bovine expressed in E. coli Sigma S9697 with activity of 6108 U/mg EP and only 35% activity left after gastric press for 30 min.

The fungal SODs of the invention were overwhelmingly and surprisingly found to have a very high gastric stability (see Gastric Stability Table). Moreover, some SODs even have higher activity under gastric stability studies than at the reference pH, indicating that they are more active at low pH. This makes fungal SODs very well suited for use in vivo by means of administration through animal feed.

Thermal Stability of Superoxide Dismutase

The commercially available E. coli and bovine SODs are tested at 25° C. and stored at −20° C. An animal feed additive for use in animal feed is prepared by a pelleting process, transported by land or sea, stored, and consumed by animals with body temperatures over 30° C. and at gastric pH conditions. Transport and pelleting may lead to temperatures reaching 45° C. Accordingly, thermal stability in each of these conditions is highly pertinent for use of a super oxide dismutase in an animal feed additive.

Test were performed on the super oxide dismutases of the invention to measure the temperature at different acidity/alkalinity to determine the temperature at which the polypeptide unfolds and denatures. As can be seen, from the “Thermal Stability Table with pH”, unfolding of the fungal superoxide dismutase takes place at over 45° C., as measured by the Tm, for all fungal superoxide dismutases at neutral pH (pH7). A further embodiment is directed to an animal feed additive comprising a fungal superoxide dismutase thermally stable at pH 7, when measured according to the method described in Example 11, such that protein unfolding (Tm) is 45° C. or more.

At gastric pH (pH 3), fungal superoxide dismutases have been found to be stable at normal body temperatures for farm animals. A further embodiment of the invention is directed to an animal feed additive comprising a fungal superoxide dismutase thermally stable at pH 3, when measured according to the method described in Example 11, such that protein unfolding (Tm) is 35° C. or more, such as 40° C. or more, such as 45° C. or more.

In a preferred embodiment, the animal feed additive of the invention is thermal stable, when measured according to the method described in Example 11. The commercially available superoxide dismutase from bovine erythrocytes and expressed in E. coli of sequence A:

For a solid formulation, the formulation may be for example as a granule, spray dried powder or agglomerate (e.g. as disclosed in WO2000/70034). The formulating agent may comprise a salt (organic or inorganic zinc, sodium, potassium or calcium salts such as e.g. such as calcium acetate, calcium benzoate, calcium carbonate, calcium chloride, calcium citrate, calcium sorbate, calcium sulfate, potassium acetate, potassium benzoate, potassium carbonate, potassium chloride, potassium citrate, potassium sorbate, potassium sulfate, sodium acetate, sodium benzoate, sodium carbonate, sodium chloride, sodium citrate, sodium sulfate, zinc acetate, zinc benzoate, zinc carbonate, zinc chloride, zinc citrate, zinc sorbate, zinc sulfate), starch or a sugar or sugar derivative (such as e.g. sucrose, dextrin, glucose, lactose, sorbitol).

In one embodiment, the composition is a solid composition, such as a spray dried composition, comprising the polypeptide having SOD activity of the invention and one or more formulating agents selected from the list consisting of sodium chloride, sodium benzoate, potassium sorbate, sodium sulfate, potassium sulfate, magnesium sulfate, sodium thiosulfate, calcium carbonate, sodium citrate, dextrin, glucose, sucrose, sorbitol, lactose, starch and cellulose. In a preferred embodiment, the formulating agent is selected from one or more of the following compounds: sodium sulfate, dextrin, cellulose, sodium thiosulfate, magnesium sulfate and calcium carbonate.

The present invention also relates to enzyme granules/particles comprising the polypeptide having SOD activity of the invention optionally combined with one or more additional enzymes. The granule is composed of a core, and optionally one or more coatings (outer layers) surrounding the core.

Typically, the granule/particle size, measured as equivalent spherical diameter (volume based average particle size), of the granule is 20-2000 μm, particularly 50-1500 μm, 100-1500 μm or 250-1200 μm.

The core can be prepared by granulating a blend of the ingredients, e.g., by a method comprising granulation techniques such as crystallization, precipitation, pan-coating, fluid bed coating, fluid bed agglomeration, rotary atomization, extrusion, prilling, spheronization, size reduction methods, drum granulation, and/or high shear granulation.

Methods for preparing the core can be found in Handbook of Powder Technology; Particle size enlargement by C. E. Capes; Volume 1; 1980; Elsevier. Preparation methods include known feed and granule formulation technologies, e.g.:

a) spray dried products, wherein a liquid enzyme-containing solution is atomized in a spray drying tower to form small droplets which during their way down the drying tower dry to form an enzyme-containing particulate material;

b) layered products, wherein the enzyme is coated as a layer around a pre-formed inert core particle, wherein an enzyme-containing solution is atomized, typically in a fluid bed apparatus wherein the pre-formed core particles are fluidized, and the enzyme-containing solution adheres to the core particles and dries up to leave a layer of dry enzyme on the surface of the core particle. Particles of a desired size can be obtained this way if a useful core particle of the desired size can be found. This type of product is described in, e.g., WO 97/23606;

c) absorbed core particles, wherein rather than coating the enzyme as a layer around the core, the enzyme is absorbed onto and/or into the surface of the core. Such a process is described in WO 97/39116.

d) extrusion or pelletized products, wherein an enzyme-containing paste is pressed to pellets or under pressure is extruded through a small opening and cut into particles which are subsequently dried. Such particles usually have a considerable size because of the material in which the extrusion opening is made (usually a plate with bore holes) sets a limit on the allowable pressure drop over the extrusion opening. Also, very high extrusion pressures when using a small opening increase heat generation in the enzyme paste, which is harmful to the enzyme;

e) prilled products, wherein an enzyme-containing powder is suspended in molten wax and the suspension is sprayed, e.g., through a rotating disk atomiser, into a cooling chamber where the droplets quickly solidify (Michael S. Showell (editor); Powdered detergents; Surfactant Science Series; 1998; vol. 71; page 140-142; Marcel Dekker). The product obtained is one wherein the enzyme is uniformly distributed throughout an inert material instead of being concentrated on its surface. Also U.S. Pat. Nos. 4,016,040 and 4,713,245 are documents relating to this technique;

f) mixer granulation products, wherein a liquid is added to a dry powder composition of, e.g., conventional granulating components, the enzyme being introduced either via the liquid or the powder or both. The liquid and the powder are mixed and as the moisture of the liquid is absorbed in the dry powder, the components of the dry powder will start to adhere and agglomerate and particles will build up, forming granulates comprising the enzyme. Such a process is described in U.S. Pat. No. 4,106,991 and related documents EP 170360, EP 304332, EP 304331, WO 90/09440 and WO 90/09428. In a particular product of this process wherein various high-shear mixers can be used as granulators, granulates consisting of enzyme as enzyme, fillers and binders etc. are mixed with cellulose fibres to reinforce the particles to give the so-called T-granulate. Reinforced particles, being more robust, release less enzymatic dust.

g) size reduction, wherein the cores are produced by milling or crushing of larger particles, pellets, tablets, briquettes etc. containing the enzyme. The wanted core particle fraction is obtained by sieving the milled or crushed product. Over and undersized particles can be recycled. Size reduction is described in (Martin Rhodes (editor); Principles of Powder Technology; 1990; Chapter 10; John Wiley & Sons);

h) fluid bed granulation, which involves suspending particulates in an air stream and spraying a liquid onto the fluidized particles via nozzles. Particles hit by spray droplets get wetted and become tacky. The tacky particles collide with other particles and adhere to them and form a granule;

i) the cores may be subjected to drying, such as in a fluid bed drier. Other known methods for drying granules in the feed or detergent industry can be used by the skilled person. The drying preferably takes place at a product temperature of from 25 to 90° C. For some enzymes it is important the cores comprising the enzyme contain a low amount of water before coating. If water sensitive enzymes are coated before excessive water is removed, it will be trapped within the core and it may affect the activity of the enzyme negatively. After drying, the cores preferably contain 0.1-10% w/w water.

The core may include additional materials such as fillers, fibre materials (cellulose or synthetic fibres), stabilizing agents, solubilizing agents, suspension agents, viscosity regulating agents, light spheres, plasticizers, salts, lubricants and fragrances.

The core may include a binder, such as synthetic polymer, wax, fat, or carbohydrate.

The core may include a salt of a multivalent cation, a reducing agent, an antioxidant, a peroxide decomposing catalyst and/or an acidic buffer component, typically as a homogenous blend.

In one embodiment, the core comprises a material selected from the group consisting of salts (such as calcium acetate, calcium benzoate, calcium carbonate, calcium chloride, calcium citrate, calcium sorbate, calcium sulfate, potassium acetate, potassium benzoate, potassium carbonate, potassium chloride, potassium citrate, potassium sorbate, potassium sulfate, sodium acetate, sodium benzoate, sodium carbonate, sodium chloride, sodium citrate, sodium sulfate, zinc acetate, zinc benzoate, zinc carbonate, zinc chloride, zinc citrate, zinc sorbate, zinc sulfate), starch or a sugar or sugar derivative (such as e.g. sucrose, dextrin, glucose, lactose, sorbitol), sugar or sugar derivative (such as e.g. sucrose, dextrin, glucose, lactose, sorbitol), small organic molecules, starch, flour, cellulose and minerals and clay minerals (also known as hydrous aluminium phyllosilicates). In one embodiment, the core comprises a clay mineral such as kaolinite or kaolin.

The core may include an inert particle with the enzyme absorbed into it, or applied onto the surface, e.g., by fluid bed coating.

The coating should encapsulate the core unit by forming a substantially continuous layer. A substantially continuous layer is to be understood as a coating having few or no holes, so that the core unit is encapsulated or enclosed with few or no uncoated areas. The layer or coating should in particular be homogeneous in thickness.

The coating can further contain other materials as known in the art, e.g., fillers, antisticking agents, pigments, dyes, plasticizers and/or binders, such as titanium dioxide, kaolin, calcium carbonate or talc.

Enzymes can be classified on the basis of the handbook Enzyme Nomenclature from NC-IUBMB, 1992), see also the ENZYME site at the internet: http://www.expasy.ch/enzyme/. ENZYME is a repository of information relative to the nomenclature of enzymes. It is primarily based on the recommendations of the Nomenclature Committee of the International Union of Biochemistry and Molecular Biology (IUB-MB), Academic Press, Inc., 1992, and it describes each type of characterized enzyme for which an EC (Enzyme Commission) number has been provided (Bairoch A. The ENZYME database, 2000, Nucleic Acids Res 28:304-305). This IUB-MB Enzyme nomenclature is based on their substrate specificity and occasionally on their molecular mechanism; such a classification does not reflect the structural features of these enzymes.

The nutritional requirements of these components (exemplified with poultry and piglets/pigs) are listed in Table A of WO 01/58275. Nutritional requirement means that these components should be provided in the diet in the concentrations indicated.

In the alternative, the animal feed additive of the invention comprises at least one of the individual components specified in Table A of WO 01/58275. At least one means either of, one or more of, one, or two, or three, or four and so forth up to all thirteen, or up to all fifteen individual components. More specifically, this at least one individual component is included in the additive of the invention in such an amount as to provide an in-feed-concentration within the range indicated in column four, or column five, or column six of Table A.

In a still further embodiment, the animal feed additive of the invention comprises at least one of the below vitamins, preferably to provide an in-feed-concentration within the ranges specified in the below Table 1 (for piglet diets, and broiler diets, respectively).

In the suitable embodiments, the invention relates to an animal feed and a method of improving one or more performance parameters in an animal comprising administering to the animal an animal feed or animal feed additive comprising one or more polypeptides having superoxide dismutase (SOD) activity, wherein the one or more performance parameters is selected from the group consisting of the European Production Efficiency Factor (EPEF), Feed Conversion Ratio (FCR), Growth Rate (GR), Body Weight Gain (WG), Mortility Rate (MR) and Flock Uniformity (FU).

These features are supported by examples 1 and 2. As it is generally known, an improved FCR is lower than the control FCR. In particular embodiments, the FCR is improved (i.e., reduced) as compared to the control by at least 1.0%, preferably at least 1.5%, 1.6%, 1.7%, 1.8%, 1.9%, 2.0%, 2.1%, 2.2%, 2.3%, 2.4%, or at least 2.5%.

The term “mortality” as used herein refers to the ratio of life animals at the end of the growth phase versus the number of animals originally included into the pond. It may be determined on the basis of a fish challenge trial comprising two groups of fish challenged by a particular fish pathogen with the aim to provoke a mortality of 40 to 80% of the animals in the untreated group. However, in the challenge group fed with a suitable concentration per Kg of feed of a mixture of at least two compounds according to the invention, the mortality is reduced compared to the untreated group by at least 5%, preferably at least, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, or at least 50%.

In some embodiments the invention relates to an animal feed and a method of improving or enhancing immune response and/or reducing inflammation and/or for the modulation of the gut flora in an animal comprising administering to the animal an animal feed or animal feed additive comprising one or more polypeptides having superoxide dismutase activity.

These features are supported by example 1 as the first two features are very much linked to oxidative stress. Different in-vitro models tested by the applicant also show that SODs optionally in combinations with a catalase are very effective to decrease oxidative stress/burst.

Dysregulating effects of heat stress and oxidative stress also help in maintaining gut integrity and function. Therefore, the invention also supports a positive modulation of the gut flora, in particular of the microbial gut flora.

The term “gut” as used herein designates the gastrointestinal or digestive tract (also referred to as the alimentary canal) and it refers to the system of organs within multi-cellular animals which takes in food, digests it to extract energy and nutrients, and expels the remaining waste.

The term gut “microflora” as used herein refers to the natural microbial cultures residing in the gut and maintaining health by aiding in proper digestion.

The term “modulate” as used herein in connection with the gut microflora generally means to change, manipulate, alter, or adjust the function or status thereof in a healthy and normally functioning animal, i.e. a non-therapeutic use.

The term “supporting immune system function” as used herein refers to the immune stimulation effect obtained by the compounds according to the invention.

In the fifth and sixth embodiment, the invention relates to a method of reducing or eliminating the use of antibiotics administered to animal feed or to a method of reducing cellular markers of reactive oxygen species or free radicals in animal body comprising administering to the animal an animal feed or animal feed additive comprising one or more polypeptides having superoxide dismutase (SOD) activity. These embodiments are supported by example 1.

In the seventh embodiment, the invention relates to an animal feed additive or animal feed premix comprising one or more polypeptides having superoxide dismutase (SOD), wherein the feed additive or premix further comprises

• • one or more polypeptides having catalase activity and/or
  • one or more vitamins, wherein the one or more vitamins is preferably a fat-soluble vitamin, for example vitamin E.

If a catalase (CAT) is added to the final feed, the final CAT concentration in the diet is within the range of 100 to 1000 mg enzyme protein per kg animal feed, such as 200 to 900 mg, 300 to 800 mg, 400 to 700 mg, 500 to 600 mg enzyme protein per kg animal feed, or any combination of these intervals.

The final CAT concentration in the diet can also be determined in Units/kg feed, which is within the range of 50 to 1000 Units per kg animal feed, such as 50 to 800 U/kg, 100 to 800 U/kg, 100 to 500 U/kg or any combination of these intervals.

As shown in example 1, such a premix has strong antioxidative properties and can be used, optionally in combination with selenium as an antioxidant in feed and feed premixes or as a replacement or partial replacement of antibiotics in animal feed.

EXAMPLES

Example 1: Heat Stress Model in Broilers: SOD and CAT Reduce Oxidative Stress Response

Background

Different stress factors inevitably influence the animal's physiology and performance with varying degrees during the production period. High ambient temperature is one of the most common stressor in modern poultry production resulting in reduced feed intake, body weight gain, and increased mortality. Because of their physiological state and greater metabolic activity, broilers are more susceptible to temperature associated environmental challenges. In addition to its effect on bird performance, the adverse effects of heat stress can range from minimal discomfort to multi-organ damage and failure, including alteration of gut permeability and function due to weakened tight junctions of the epithelial layer. Therefore, heat stress-induced disturbance of gut integrity may lead to leaky gut syndrome thus increasing the susceptibility of birds to enteric pathogens that may lead to systemic bacterial infections. Moreover, heat stress can cause oxidative damage by increasing the formation of reactive oxygen species.

Hypothesis and Objective

The central hypothesis is that the adverse effects of heat stress on performance and health of chickens can be mitigated by incorporating effective feed additives into poultry diets. Certain compounds that can alter the dysregulating effects of heat stress may help in maintaining gut integrity and function. Therefore, the main objective is to alleviate the impact of heat stress challenge on performance and overall health of broilers by timely supplementation of non-drug dietary additives.

Experimental Design

A 35-day trial with only male broiler chicks will be run in floor pens with eight replicate pens per treatment and 20 birds/pen. Birds are randomly assigned to treatment groups in a 2×4 factorial arrangement that includes heat stress (optimal or high heat) and dietary treatments (basal diet or feed additives) as per FIG. 1. A total of 4 animal rooms are used (2 controls and 2 heat stress) each housing half the replicate pens (n=4) per group.

Three birds per pen for each of the three sampling times (3×3=9) are randomly tagged at placement with necktags of different colour (or number) per sampling time to ensure random sampling. At sampling, the two of the three birds with the closest to average BW are selected for sampling and their BW is recorded. If less than two of those birds are available or healthy, other random birds can be selected in the pen to complete the two sampled birds.

Treatment groups including controls and challenge from d 28 to 35 (heat stress) are as follows:

Heat Stress Protocol

Heat stress protocol is performed as planned during the finisher feeding phase (d 28 to d 35). For the heat stress groups, temperature is maintained at 35±1° C. (10° C. above the recommended temp.) and applied once daily from 10 am to 2 μm, then reduced again to 25 C+/−1 for the remainder of the day. Relative humidity is monitored and maintained at RH<50%. Birds in the separate ‘optimal heat’ group are kept under normal constant recommended temperatures (25° C.+/−1). The birds' (2 birds/pen) rectal temperature was monitored daily with a rectal probe during the heat stress period (d 28-35).

Feed

The diets consist of corn/soybean in mash as Starter (d 1-21) and Grower (d 22-35) and will be formulated according to commercial specifications for the broilers used (Ross or Cobb) to meet or exceed NRC recommendations (Table 4). Test products are sprayed onto a small amount (20 kg) of the basal diet and mixed with the rest of the batch for each diet.

Parameters Evaluated

• 1. Performance: Standard performance parameters including body weight (BW), weight gains (BWG), feed intake (FI), and feed conversion ratios (FCR) are evaluated on days 10, 21, 27, and 35 on a per pen basis. Any mortality is recorded daily and feed consumption (+FCR) corrected for accordingly. Average bird performance is calculated based on the number of birds per each pen (i.e. replicate) after adjusting for any mortality.
• 2. Rectal temperature: The birds' rectal temperature is monitored daily during the heat stress period (d 28-35). Two birds from each replicate pen are selected and tagged for body temperature measurement using a rectal probe daily at a pre-set time range (e.g. 1-2 μm).
• 3. Antioxidant parameters: Based on the stress challenge employed, blood serum and liver are sampled at 27, 28 and 35 d from two birds of average BW per pen to determine parameters related to oxidative stress:
  • a. MDA, CAT, GSH-Px, and SOD: On d 27, two birds per replicate pen are tagged for blood sampling. Blood samples are taken by wing venipuncture on d 27, d 28, and d 35 (alternating sides), and collected into red-topped serum tubes. The tubes are transferred to the main lab and centrifuged at 2,000×g for 5 min to collect sera, which are stored at 20° C. until analysis. Antioxidant analyses in blood samples are carried out with commercial kits according to the manufacturer recommendations.
  • b. Optional analyses. Depending on the results of the other parameters, it might be decided to measure Vitamin E, vitamin A, cysteine, cystine, methionine, and glutamine in the liver, using standard HPLC protocols are used to measure vitamins A and E, as well as profile amino acids (separated on a single column). They are not included in the initial budget.
• 4. Liver bacterial load: At the end of the study (d 35), liver samples are collected from one bird per pen in sterile sampling bags to determine total bacterial load in liver. To establish standard curves for bacterial quantification, pure bacterial (E. coli, and Clostridium perfringens) suspensions are individually cultured in corresponding selective media, the DNA extracted (commercial extraction kits), and its concentration determined (Nano-Drop). The DNA stocks are serially diluted (6 times) and real time quantitative PCR performed to determine the threshold cycle (Ct) value related to each pure sample. The standard curves are established with the DNA concentrations and corresponding relative Ct values. DNA from liver tissue samples are extracted via special kits. The abundance of DNA copies in DNA samples from liver tissue is determined by qPCR. For this purpose, specific primers for bacterial 16S rRNA gene are used, and the bacterial loads per gram tissue are calculated using the generated standard curves.
• 5. Carcass/body composition (no additional cost): Dual Energy X-Ray Absorptiometry (DXA) analysis is performed on 3 birds per pen on d 35 to assess the effects of products on various measurements of carcass/body composition. These include body fat percentage, fat tissue, lean tissue, and bone mineral density (BMD), in addition to bone mineral content (BMC) and carcass area, both used for calculation purposes.
• 6. Gene expression: Liver and intestinal (jejunum) tissue samples are taken (2/pen) on d 27, d 28 and d 35 from birds with average pen weight (sampled above for histology). Liver weight is measured and relative weight calculated per bird. Tissues are collected, minced, snap-frozen, and stored at 80° C. until qPCR analysis. Target genes to be measured include immunity-related to heat stress (oxidative stress, heat shock proteins, inflammatory markers), tight junction genes, host defense peptides, and nutrient transporters. The final list of targets is determined based on study outcome. Transcript analysis for a subset of targets is measured in each collected tissue.

Heat Stress Protocol

Heat stress protocol was performed as planned during the last week of the experiment (d 28 to d 35). For the heat stress groups, temperature was raised and maintained at 35±1° C. (10° C. above the recommended temp.) and applied once daily from 10 am to 2 pm, then reduced again to 25° C.+/−1 for the remainder of the day. Relative humidity was monitored and maintained at RH<50%. Birds in the separate ‘optimal heat’ group were kept under normal constant recommended temperatures (25° C.+/−1). The birds' (2 birds/pen) rectal temperature was monitored daily with a rectal probe during the heat stress period (d 28-35).

Sampling Procedures

Blood, liver and intestinal (jejunum) tissue samples were taken on d 27 (1/pen), d 28 (2/pen) and d 35 (2/pen) from birds with average pen weight for qPCR and antioxidant assay analyses. The livers were weighed and observed for any pathological findings.

DXA Analysis

Dual Energy X-Ray Absorptiometry (DXA) analysis was performed on 2 birds per pen on d 35 to assess various measurements of carcass/body composition. Birds were individually wing-banded, sacrificed by cervical dislocation and subsequently defeathered and carcasses stored at −20° C. until DXA analysis. Birds were thawed and 10 birds were scanned at a time using GE Healthcare Lunar Prodigy Advance, System ID PA+130,744 (GE, Madison, Wis.).

Total RNA Extraction and Reverse Transcription

Total RNA was extracted from individual liver and intestinal tissues using the Direct-zol RNA Kits (Zymo Research) according to the manufacturer's recommendations. Tissue samples were removed from −80° C. and placed on ice. A 20-30 mg aliquot of each sample was weighed, placed into a 2-mL microcentrifuge tube, and kept on ice until homogenization. Total RNA concentration was determined at optical density (OD) of 260 (NanoDrop-1000, Thermo Fisher Scientific, Waltham, Mass.), and RNA purity was verified by evaluating the 260/280 OD ratios. Total RNA was diluted to 0.2 μg/μL in nuclease-free water. Reverse transcription was accomplished using the high capacity cDNA Reverse Transcription kit (Applied Biosystems, Carlsbad, Calif.) following the manufacturer's protocol and the cDNA was stored at 20° C.

Quantitative Real-Time PCR

Quantitative real-time PCR (qRT-PCR) was performed using an ABI 7500 Fast Real-Time PCR System (Applied Biosystems). The cDNA was diluted 1:20 in nuclease-free water, and 1 μL of the diluted cDNA was added to each well of a 96-well plate. Next, 9 μL of RT-PCR master mix containing 5 μL of Fast SYBR Green Master Mix (Applied Biosystems), 0.5 μL each of 2 μM forward and reverse primers, and 3 μL of sterile nuclease-free water per reaction were added to each well for a final volume of 10 μL. During the PCR reaction, samples were subjected to an initial denaturation phase of 95° C. for 20 s followed by 40 cycles of denaturation at 95° C. for 3 s and annealing and extension at 60° C. for 30 s. Gene expression was analyzed using glyceraldehyde-3-phosphate dehydrogenase (GAPDH) as an endogenous control. Each reaction was run in duplicate. Results from qRT-PCR were analyzed using the 7500 Real-Time PCR software (Applied Biosystems). The primer pairs used are shown in Table 4. Average gene expression relative to the GAPDH endogenous control for each sample was calculated using the 2^−ΔΔct method (Livak and Schmittgen, 2001).

Antioxidant Analysis

Based on the stress challenge employed, blood serum and liver samples were analyzed to determine thiobarbituric acid reactive substances (TBARS), catalase (CAT), glutathione peroxidase (GPx), and superoxide dismutase (SOD) activities on d 27, d 28 and d 35. Antioxidant analyses were carried out with commercial assay kits (Cayman, Ann Arbor, Mich.).

Statistical Analysis

Data were subjected to a 2-way ANOVA using the GLM procedure of JMP (Pro13). The models included heat stress (optimal and high heat) and dietary treatments (basal diet or feed additives) as the main factors, and the 2-way interactions. Post hoc testing was only carried out for significant interactions and was performed using simple effect analysis. The probability P<0.05 was considered significant unless otherwise noted.

Results

Experimental results are shown in FIGS. 1 to 15 and can be summarized as follows:

Performance Parameter:

FIG. 8: FCR 0-7 d

• • There was an effect of SOD 400+CAT 100 on BW gain and feed intake in the overall period.
  • A high performance effect of enzymes on BWG and FCR was present in the first week. As reported in FIGS. 7 & 8, body weight gain (BWG) and feed conversion ratio (FCR) were improved in birds fed the diets containing either Pro. Low (T3&T7) or Pro. High (T4&T8) compared to birds fed the control diet.
  • Feed intake (FI) and mortality were not affected among the treatment groups during the first week (d 0-7). In particular, a numeric reductions in mortality during heat stress and over the entire trial could be observed.
  • Birds fed the diets containing Vit E+Se, Pro. Low, and Pro. High had higher Feed intake compared to the control group and also tended to have higher BWG between d 7-14. Similarly, BW and FI were higher in birds fed those diets containing Vit E+Se, Pro. Low, and Pro. High between d 0-14.
  • Birds fed antioxidant enzymes or Vit E & Se did not perform better during heat stress. However, numerically there was less mortality in birds fed antioxidants (enzymes or Vit E& Se) compared to the control during HS.

The data presented above show that an animal feed additive comprising at least one or more polypeptides according to the present invention improves one or more performance parameters selected from the group consisting of

• • Feed Conversion Ratio (FCR),
  • Growth Rate (GR), Body Weight Gain (WG),
  • Mortality Rate (MR).

Other Parameters:

With respect to markers for oxidative and cellular stress and immune function a significant interaction was observed in the HSP90 gene expression between dietary and heat stress treatments. In particular, the heat challenge significantly upregulated the expression of GPx, SOD, HSP70, HSP90, and TLR4, and downregulated that of GST, IL-10, TNFα, and IFNγ in the liver on d 27/28.

A) Liver Gene Expression

The dietary treatments had significant increase in liver GPx (pre-heat stress) with the lowest doses of enzymes (FIG. 9—liver GPx, nmol/min/mL (measured day 27))

B) Measurement of Heat Shock Proteins (HSP), which are Indicators of Cellular Stress.

With respect to HSP

• • a significant reduction of jejunum gene expression of HSP70 (FIG. 10—(day 28)) and liver gene expression of HSP70 (FIG. 11—(day 35)) during heat stress at the lowest dose of enzymes and
  • a numeric reduction in liver gene expression of HSP90 during heat stress was observed.C) Immune function.

The enzyme according to the present invention also show a positive effect on immune function. The treatments show a significant reduction of liver iNOS prior to heat stress challenge (FIG. 12—liver iNOS (mediator of inflammation) pre-heat stress (d 27)) or TLR2, IL-1B, IL-10, TNFa, and INFy (FIG. 13—liver gene expression of IL-10 (anti-inflammatory) during heat stress (d 35); FIG. 14—liver gene expression of TNF alpha (pro-inflammatory) during heat stress (d 35); FIG. 15 liver gene expression of INF gamma (pro-inflammatory) during heat stress (d 35)).

The results on all these other parameters clearly show that the enzymes according to the present invention help

• • to reduce
    • heat-, cold-, nutritional- and oxidative stress,
    • cellular markers of reactive oxygen species or free radicals,
    • inflammation and
  • to improve or enhance immune response in the animal.

Piglet Source: Piglets (post-weaned, at 21 days of age, called Day 0) are collected in early am (day of placement or Day 0), weighed (2 barrows & 2 gilts per pen), and assigned to each experimental pen. Each piglet is weighed individually and assigned to a pen, with very high and very low body weights excluded from the study. After all piglets are assigned to a pen, the body weights are checked to ensure no treatment is more than 1 standard deviation from another treatment.

The basal diet is shown in FIG. 16.

Experimental results on FCR (d 0-42) are shown in FIG. 17:

• • There was significant difference observed in growth performance between positive and negative control.
  • Combining SOD & CAT or feeding CAT and SOD alone gave similar performance to the antibiotic treatment and significantly better than NC.

Example 3: Efficacy of Antioxidant Enzymes (SOD and CAT) Supplemented at Different Doses Alone or in Combination on the Growth Performance of Early Weaned Piglet

Summary

The effect of antioxidant enzymes (SOD and CAT) alone at different doses and in combination on the growth performance of early weaned piglets was evaluated in a trial run. A total of eight treatments were tested during the study: 6 test groups: SOD (Product A, SEQ ID No. 1 at 1250 and 2500 U/kg), CAT (Product B, SEQ ID NO 7 and Product C, SEQ ID NO 250 at 100 U/kg) and 2 combinations (A 500 U/kg+B 100 U/kg; and A 500 U/kg+B 100 U/kg); were compared against a Positive Control feed (fed with Avilamycin at 90.7 g/lb) and a Negative Control (standard ration). Each of treatments contained 12 replicates per treatment randomly assigned and containing 5 male piglets per replicate for a total number of 480 animals on study. Piglets were randomly assigned to treatments on Trial Day 0 (post-weaning at 21 days of age). At 42 days of age, live performance (growth weight gain and feed conversion) was determined. All rations were formulated with an increase of approximately 5-6% additional crude protein above normal commercial levels. Blood samples were collected at day 0, 14 and 42 to evaluate oxidative stress parameters at DSM. Gut tissue samples at the duodenum and ileum to evaluate gene expression linked to oxidative stress, and intestinal content (ileum and caecum), to study the microbiome population, were collected from 12 animals at the beginning of the trial (baseline) and one animal per pen (12 piglets×8 treatments) at day 14 and at day 42. For the entire grow-out period (Days 0-42), body weight gain showed significant improvement over the Negative Control group when piglets were fed diets containing 2000 U/kg of SOD (Product A), 100 U/kg of CAT B, and both combination of 400 U/kg of SOD (Product A) with 100 U/kg of both CAT products B & C, with the greatest improvements coming with the combination of 400 U/kg of SOD with 100 U/kg of CAT B, which also performed statistically similar to the Positive Control ration that contained Avilamycin at 90.7 g/lb. Feed conversion improved significantly between Positive Control and Negative Control.

Test System

The commercial-simulated test model employed in this study used piglets reared under a normal swine industry Starter diet (Trial Day 0-21) and Grower diet (Trial Day 21-42), reared on slatted floors. Ration formulations were conducted via computer-generated linear regression program that simulates formulations conducted during practical swine production techniques. Treatments were tested in male piglets. Piglets were continuously fed their experimental diets from time of placement on Trial Day 0 to Trial Day 42.

Piglets were weighed and randomly placed into each pen on Trial Day 0 and fed their respective diets. Each pen had sufficient floor density, feeder and waterer space for each grow-out area for the piglets. Following 42 days of grow-out, piglets were weighed, feed consumption determined, and feed conversion (feed consumed/body weight) calculated.

Materials and Methods

Experimental Design

A total of 500 male piglets (a sufficient number to ensure availability of at least 480 healthy male piglets for the conduct of the study) were obtained from a swine breeder on Trial Day 0 (upon weaning, when the piglets were 21 days of age). Piglets were fed their respective treatment feed ad libitum from Trial Day 0 to Trial Day 42.

Housing and Daily Observations

Each experimental test unit of swine pens was housed in separated pens, located in a room containing forced air heaters with a cross-house ventilation system. Piglets were placed in a 6 ft×6 ft pen floor area with a minimum of 9.0 ft² per piglet (without feeder and waterer space) provided. At least two nipple drinkers per pen (via well water) provided water. Piglets were observed daily for overall health, behavior and/or evidence of toxicity, and environmental conditions. Temperature in the test facility was checked daily. Drinking water and feed were confirmed to be provided ad libitum. No type of medication (other than test material) was administered during the entire feeding period.

Data and Observations

Live performance body weights and feed intakes were collected on Days 0, 14, 21, and 42 during the growing period. Weight gain, feed intake, feed:gain ratio (feed efficiency) were calculated for 0-42 days of age between weaning and Trial Day 42. Differences between piglets fed control and test groups were statistically evaluated at P<0.05 in a typical ANOVA analysis of variance test model, employing Treatment×Replicate RCB (Randomized Complete Block). Control group was considered to be the following: Treatment 2, containing Avilamycin at 90.7 g/lb.

At the end of the study, all piglets were humanely euthanized and were disposed of according to local regulations via on-farm composting techniques.

Diet and Water Administration

Diets were fed in two feed phases: Starter diet (0-21 days of age) and Grower diet (21-42 days of age). All diets were offered ad libitum, without restriction. Fresh well water (from the research facility deep well) was provided ad libitum.

Results

For the entire grow-out period (Days 0-42), body weight gain (FIG. 18) showed significant improvement over the Negative Control group (no added test materials) when piglets were fed diets containing 2000 U/kg of Product A, 100 U/kg of Product B, and a combination of 400 U/kg of Product A with 100 U/kg of both Product B and Product C, with the greatest improvements coming with the combination of 400 U/kg of Product A with 100 U/kg of Product B, which also performed statistically similar to the Positive Control ration that contained Avilamycin at 90.7 g/lb. As shown in FIG. 19, feed conversion improved between Treatment 2 (Positive Control) and Treatment 1 (Negative Control) over the period of d0-d42. In particular, inclusion of SOD+CAT (independently of the candidate B or C) in the ratio 400:100 U/kg showed significant improvement on FCR performance.

In conclusion, the use of a combination of 80 ml/MT of Product A and either 4 ml/MT or 20 ml/MT of Product B appeared to significantly improve 0-42 days of age body weight gains and feed conversion as compared to a standard control ration. Therefore, when commercial piglets are grown on concrete slat floors, this combination appears to have the great potential to result in better live performance.

Analysis and calculation of body weight coefficient of variation at day 14 shows a significant effect of the treatment according to the invention on CV of BW. The data is shown in table 11. The results show that the enzymes according to the invention improve flock uniformity compared to the control T1.

Example 4: Effect of Antioxidant Enzymes (SOD and CAT) Alone or in Combination on Plasmatic Antioxidant Enzymes, Oxidative Stress Index and Intestinal Gene Expression Response of Weaned Piglets (Based on Animal Trial of Example 3)

Summary

The objective of this study was to evaluate anti-oxidant enzymes supplementation (SOD and CAT) alone and in combination in early weaned piglets, and if these enzymes can potentially alleviate the oxidative stress impact on weaned piglets and consequently improve the growth performance. In the in vivo trial (example 3), plasma samples were collected at day 0 (baseline, weaning moment), day 14 and day 42 of the study for additional analysis.

Piglets supplemented with CAT alone showed a significant increase in the plasmatic antioxidant activity (PAT). At day 42, also piglets supplemented with CAT showed a significant increase of GPx activity. Gene expression showed significant modulation at day 14. In duodenum at day 14, the supplementation of antioxidant enzymes (SOD+CAT) showed a downregulation of the genes that encode NQO1 (protecting the cells against Oxidative Stress OS) and the anti-oxidant enzyme GSTP1 (p=0.07 and p=0.005 respectively) suggesting that diet supplementation with a combination of SOD and CAT decreases stress protein expressions at the beginning of small intestine of weaned piglets. SCARA3 showed also a significant increase in the same group (p=0.003), avoiding accumulation of ROS. At the duodenum, the gene that encodes the antioxidant enzyme GPX1 showed a significant upregulation in piglets supplemented with CAT alone compared to control group and those results are in agreement with the GPx plasmatic activity found. And at the ileum level, supplementation of CAT and SOD alone showed a upregulation on the protecting protein NQO1 but a downregulation on HSP70, and piglets supplemented with SOD+CAT showed a downregulation on the genes NOX5, oxidative stress marker, and CAT, antioxidant enzyme. Those data provide evidence that diet supplementation with a SOD, CAT and the combination of both enzymes, potentially decrease oxidative stress status in weaned piglets.

Total RNA was extracted from tissues (stored at −20° C. in RNA later) by lysing tissue with FastPrep® 24 (MP Biomedicals, Illkirch, France), using the phenol-chloroform method (TRIzol reagent; Invitrogen, Invitrogen, Cergy Pontoise, France) followed by purification using RNeasy columns by automated method with the Qiacube HT (Qiagen, Courtaboeuf, France). The concentration of RNA was measured by NanoDrop ND-1000 Spectrophotometer (Thermo Fisher Scientific, Illkirch, France) and the purity was estimated by A260/A280 ratio. RNA integrity was assessed by using the Agilent 2100 Bioanalyzer (Agilent Technologies, Basel, Switzerland). The threshold of the RNA Integrity Number (RIN) was set at 7.5 to validate sufficient quality of the RNAs.

The reverse transcription was performed using RT² First Strand Kit (Qiagen, Courtaboeuf, France) with 500 ng of total RNA. The reaction mix was incubated 5 minutes at 42° C. for genomic DNA elimination, followed by the reverse transcription 15 minutes at 42° C. The inactivation of the enzyme was performed by heating 5 minutes at 95° C. The resultant cDNAs were amplified with RT² SYBR Green Mastermixes (Qiagen, Courtaboeuf, France) for real-time PCR. The expression of target genes was normalized with housekeeping genes listed in the table below:

Gene Symbol Official Full Name
UBC         ubiquitin C
GAPDH       glyceraldehyde-3-phosphate dehydrogenase
The thermal cycling was run on Light Cycler 96 (Roche Diagnostics, Meylan, France) with the following program: 95° C. 10 min, followed by 40 cycles of denaturation at 95° C. 15 seconds and hybridization/elongation at 60° C. 1 min. The Delta Ct method was used to determine expression of target genes (Livak and Schmittgen, 2001)

Oxidative Stress Index: FRAS5

An oxidative stress index was calculated as the ratio of reactive oxygen metabolites (ROM) and Plasma antioxidant capability (PAT) determined in plasma and liver lysate samples. ROM and

PAT were analyzed using commercially methods (d-ROM fast test and PAT test) on FRAS5 instrument (Innovatics Laboratory, Philadelphia, USA). For d-ROM test, 10 μL of sample was mixed with an acidic buffer. Then, a chromogen was added, and measured photometrically at 505 nm. The results are expressed in UCarr (1 UCarr=0.08 mg of H2O2/dl). For PAT test, 10 μl of sample was added in a colored solution (mix of source ferric ions and chromogen). The intensity of chromatic change was measured at 505 nm. The results are expressed in UCor (1 UCor=1.4 μM of Vitamin C equivalent). The oxidative stress index was calculated as the ratio of d-ROMs test value to PAT test value.

Total Proteins Determination

The concentration of total proteins was determined in liver lysate and plasma, using the Pierce™ BCA Protein Assay Kit (Thermo Fisher Scientific, Illkirch-Graffenstaden, France). The samples were processed following the supplier's recommendations. Plasma samples were diluted 100 times. 25 μL of standards or samples were added to 200 μL of working reagent and incubated 30 minutes at 37° C. The colorimetric intensity was measured at 562 nm. Results are expressed in μg of total protein per mL of sample.

Plasma CAT Activity

The activity of the catalase was determined using the Amplex® Red Catalase Assay Kit (Molecular Probes A22180). Briefly 25 μL of standards, plasma (adjusted at 1 μg of protein/well) was mixed with 25 μL of 40 μM H₂O₂ solution and incubated for 30 minutes at room temperature. 50 μL of the Amplex Red/HRP working solution was added to each microplate well containing the samples and standards and incubated 30 min at 37° C. protected from light. The absorbance was measured at 560 nm, and the concentration of CAT in the samples was calculated based on the standard curve.

Plasma SOD Activity

The activity of the superoxide dismutase was determined using the SOD determination KIT (Sigma 19160) and quantity if reagent in each well is described in table 15 below:

Plasma samples were adjusted to bring 60014 of total protein in the reaction. The plates were incubated for 20 min at 37° C., and the absorbance was read at 450 nm. The SOD activity (SODA) was measured as follow and calculated using the standard curve:

SODA={[(A blank 1−A blank 3)−(A sample−A blank 2)]/(A blank−1A blank 3)}*100

Plasma GPx Activity

The activity of the Glutathione peroxidase was determined using the GPx determination KIT (abcamab102530). Briefly, 40 μL of the colorimetric reaction mix was added to 100 μL of standards and 10 μL of cumene hydroperoxide was added to the standards and to the 50 μL of samples (Plasma samples were adjusted to bring 600 μg of total protein in the reaction). The absorbance at 340 nm was measured (A1), and after 5 min at 25° C., a second measurement was done (A2).

The GPx activity was calculated as follow:

$1\text{)}\Delta A\_340\mathrm{nm}=\left(\left(\mathrm{Sample}A1-\mathrm{Sample}A2\right)-\left(\mathrm{Reagent}\mathrm{control}A1-\mathrm{Reagent}\mathrm{control}A2\right)\right)$ $2\text{)}B=\frac{(\Delta A\_340\mathrm{nm}-\mathrm{intercept}}{\mathrm{Slope})}$ $3\text{)}\mathrm{GPx}\mathrm{Activity}=\frac{\left(B\right)}{\left(T2-T1\right)*V)}*D$

Where:

B=NADPH amount that was decreased between T1 and T2 (in nmol).

T1=Time of the first reading (A1) (minutes).

T2=Time of second reading (A2) (minutes).

V=Pretreated sample volume added into the reaction well (mL).

D=Sample dilution factor.

Statistical Analysis

ANOVA was performed for plasmatic parameters and student test was calculated to evaluate the significance of the differences observed in gene expression.

Results

Plasmatic Parameters

Results of the plasmatic parameters (SOD, CAT and GPx, OS) at day 0, 14 and 42 can be summarized as follows:

• • At day 14, the plasmatic activity of the antioxidant enzymes SOD, CAT and GPx were higher than at day 0.
  • For the GPx activity, at day 42, the addition of the enzymes in the diet showed a significant increase in group receiving either the CAT alone or in combination with the SOD.
  • At day 0, the reactive oxygen metabolites (d-ROM) and the 051 were higher than at day 14 and 42, reflecting the level of response to the stress generated in the early weaning period of the animals, and indicating a higher sensitivity of this biomarker in acute stress compared to the activity of SOD and CAT.
  • Interestingly, the d-ROM showed an increase in animals supplemented with CAT or CAT+SOD in both time point.
  • At day 14, the plasmatic antioxidant capacity showed a significant difference between experimental groups (p<0.0001) with an increase in group supplemented with CAT or SOD+CAT.

Gene Expression Targeting Oxidative Stress

Results of the gene expression analysis are shown in Table 16 (Gene expression fold change of oxidative stress related genes in duodenum at day 14), Table 17 (Gene expression fold change of oxidative stress related genes in ileum at day 42) and can be summarized as follows:

• • In the group supplemented with both enzymes (SOD+CAT), a downregulation of the genes that encode NQO1 (protecting the cells against OS) and the anti-oxidant enzyme GSTP1 (p=0.07 and p=0.005 respectively) was observed suggesting that diet supplementation with a combination of SOD and CAT decreases stress protein expressions at the beginning of small intestine of weaned piglets.
  • SCARA3 showed also a significant increase in the same group (p=0.003), avoiding accumulation of ROS.
  • In duodenum at day 42, only the gene that encode the antioxidant enzyme GPX1 gene showed a significant upregulation (p=0.019) in piglets supplemented with CAT alone compared to control group with a fold change of 1.34. Those results are in line with the GPx plasmatic activity found in the piglets after 42 days of supplementation.
  • Piglets supplemented with SOD alone showed a upregulation on the protecting protein a NQO1
  • Similarly to SOD supplementation alone, piglets supplemented with CAT alone showed an upregulation of NQO1. Besides that, piglets showed a upregulation on antioxidant enzyme GSTP1 and a downregulation of a redox marker NOX5.
  • Finally, piglets supplemented with SOD+CAT showed a downregulation on the genes NOX5, oxidative stress marker, and CAT, antioxidant enzyme.

CONCLUSION

Plasmatic antioxidant enzymes, specially SOD and CAT, showed a clear increase at day 14, independently of the treatment, indicating that the oxidative stress situation induced by piglet weaning is progressively corrected during the postweaning period. A significant increase in the plasmatic antioxidant activity in piglets supplements with CAT alone could be observed. At day 42, piglets supplemented with CAT showed a significant increase of GPx activity.

Gene expression showed significant modulation at day 14 and not at day 42. In duodenum at day 14, the supplementation of antioxidant enzymes (SOD+CAT) showed a downregulation of the genes that encode NQO1 (protecting the cells against OS) and the anti-oxidant enzyme GSTP1 (p=0.07 and p=0.005 respectively) suggesting that diet supplementation with a combination of SOD and CAT decreases stress protein expressions at the beginning of small intestine of weaned piglets. SCARA3 showed also a significant increase in the same group (p=0.003), avoiding accumulation of ROS.

At the duodenum, only the gene that encode the antioxidant enzyme GPX1 showed a significant upregulation in piglets supplemented with CAT alone compared to control group and those results are in agreement with the GPx plasmatic activity found at 42 days. And at the ileum level, supplementation of CAT and SOD alone showed a upregulation on the protecting protein NQO1 and piglets supplemented with SOD+CAT showed a downregulation on the genes NOX5, oxidative stress marker, and CAT, antioxidant enzyme. Those data provide evidence that diet supplementation with a SOD, CAT and the combination of both enzymes, potentially decrease oxidative stress status in weaned piglets.

Cloning

Aspergillus niger MBin118 is disclosed in WO 2004/090155.

The SEQ ID NO 1 polypeptide coding sequence was cloned from Trichoderma reesei QM6a DNA by PCR.

Trichoderma reesei QM6a was cultivated in 100 ml of YP+2% glucose medium in 1000 ml Erlenmeyer shake flasks for 5 days at 20° C. Mycelia were harvested from the flasks by filtration of the medium through a Buchner vacuum funnel lined with MIRACLOTH® (EMD Millipore, Billerica, Mass., USA). Mycelia were frozen in liquid nitrogen and stored at −80C until further use. Genomic DNA was isolated using a DNEASY® Plant Maxi Kit (QIAGEN GMBH, Hilden Germany) according to the manufacturer's instructions.

Genomic sequence information was generated by Illumina MySeq (Illumina Inc., San Diego, Calif.). 5 rigs of the isolated Trichoderma reesei QM6a genomic DNA was used for library preparation and analysis according to the manufacturer's instructions. A 300 bp, paired end strategy was employed with a library insert size of 200-500 bp. The reads were subsequently fractionated to 25% followed by trimming (extracting longest sub-sequences having Phred-scores of 10 or more). These reads were assembled using ldba version 0.18. Contigs shorter than 200 bp were discarded. Genes were called using GeneMark.hmm ES version 2.3c and identification of the catalytic domain was made using “SOD_Cu” Hidden Markov Model provided by Pfam. A Swissprot entry of the identical sequence is also available: GORPL7 HYPJQ. The polypeptide coding sequence for the entire coding region was cloned from Trichoderma reesei QM6a genomic DNA by PCR using the primers (SEQ ID NO: A and SEQ ID NO: B) described below.

In-Fusion™ Advantage PCR Cloning Kit Cat. nr 639620

The amplification reaction (50 μl) was performed according to the manufacturer's instructions (Thermo Scientific) with the following final concentrations:

1× Phusion HC buffer200 uM dNTP

2.0 mM MgCl₂

0.5 uM of each primer of SEQ ID NO: A+B10 ng of Trichoderma harzianum O4 genomic DNA.

The PCR reaction was incubated in a DYAD® Dual-Block Thermal Cycler (BioRad, USA) programmed for 1 cycle at 98° C. for 2 minutes; 30 cycles each at 98° C. for 10 seconds and 72° C. for two minutes followed by 1 cycle at 72° C. for 6 minutes. Samples were cooled to 10° C. before removal and further processing.

Five μl of the PCR reaction were analyzed by 1% agarose gel electrophoresis using 40 mM Tris base, 20 mM sodium acetate, 1 mM disodium EDTA (TAE) buffer. A major band of about 1 kb was observed. The remaining PCR reaction was purified directly with an ILLUSTRA™ GFX™ PCR DNA and Gel Band Purification Kit (GE Healthcare, Piscataway, N.J., USA) according to the manufacturer's instructions.

Two μg of plasmid pDau109 was digested with Bam HI and Hind III and the digested plasmid was run on a 1% agarose gel using 50 mM Tris base-50 mM boric acid-1 mM disodium EDTA (TBE) buffer in order to remove the stuffer fragment from the restricted plasmid. The bands were visualized by the addition of SYBR® Safe DNA gel stain (Life Technologies Corporation, Grand Island, N.Y., USA) and use of a 470 nm wavelength transilluminator. The band corresponding to the restricted plasmid was excised and purified using an ILLUSTRA™ GFX™ PCR DNA and Gel Band Purification Kit. The plasmid was eluted into 10 mM Tris pH 8.0 and its concentration adjusted to 20 ng per μl. An IN-FUSION® PCR Cloning Kit (Clontech Laboratories, Inc., Mountain View, Calif., USA) was used to clone the 1450 bp PCR fragment into pDau109 digested with Bam HI and Hind III (20 ng). The IN-FUSION® total reaction volume was 10 μl. The IN-FUSION® total reaction volume was 10 μl. The IN-FUSION® reaction was transformed into FUSION-BLUE™ E. coli cells (Clontech Laboratories, Inc., Mountain View, Calif., USA) according to the manufacturer's protocol and plated onto LB agar plates supplemented with 50 μg of ampicillin per ml. After incubation overnight at 37° C., transformant colonies were observed growing under selection on the LB plates supplemented with 50 μg of ampicillin per mL.

Several colonies were selected for analysis by colony PCR using the pDau222 pDau109 vector primers described below. Four colonies were transferred from the LB plates supplemented with 50 μg of ampicillin per ml with a yellow inoculation pin (Nunc A/S, Denmark) to new LB plates supplemented with 50 μg of ampicillin per ml and incubated overnight at 37° C.

Each of the three colonies were transferred directly into 200 μl PCR tubes composed of 5 μl of 2× Thermo Scientific Dream Tag™ PCR Master Mix (Thermo Fisher Scientific, Rockford, Ill., USA), 0.5 μl of primer 8653 (10 pm/μl), 0.5 μl of primer 8654 (10 pm/μl), and 4 μl of deionized water. Each colony PCR was incubated in a DYAD® Dual-Block Thermal Cycler programmed for 1 cycle at 94° C. for 60 seconds; 30 cycles each at 95° C. for 30 seconds, 60° C. for 45 seconds, 72° C. for 60 seconds, 68° C. for 10 minutes, and 10° C. for 10 minutes.

Four μl of each completed PCR reaction were submitted to 1% agarose gel electrophoresis using TAE buffer. All four E. coli transformants showed a PCR band of about 1 kb. Plasmid DNA was isolated from each of the four colonies using a QIAprep Spin Miniprep Kit (QIAGEN GMBH, Hilden Germany). The resulting plasmid DNA was sequenced with primers 8653 and 8654 using an Applied Biosystems Model 3730 Automated DNA Sequencer using version 3.1 BIG-DYE™ terminator chemistry (Applied Biosystems, Inc., Foster City, Calif., USA).

One plasmid was chosen for transforming Aspergillus oryzae MT3568. A. oryzae MT3568 is an amdS (acetamidase) disrupted gene derivative of Aspergillus oryzae JaL355 (WO 2002/40694) in which pyrG auxotrophy was restored by inactivating the A. oryzae amdS gene. Protoplasts of A. oryzae MT3568 were prepared according to the method described in European Patent, EP0238023, pages 14-15.

E. coli 190 containing the selected plasmid was grown overnight according to the manufacturer's instructions (Genomed) and the plasmid DNA was isolated using a Plasmid Midi Kit (Genomed JETquick kit, cat.nr. 400250, GENOMED GmbH, Germany) according to the manufacturer's instructions. The purified plasmid DNA was transformed into Aspergillus oryzae MT3568. A. oryzae MT3568 protoplasts were prepared according to the method of Christensen et al., 1988, Bio/Technology 6: 1419-1422. The selection plates consisted of COVE sucrose with +10 mM acetamide+15 mM CsCl+TRITON® X-100 (50 μl/500 ml). The plates were incubated at 37° C. Briefly, 8 uls of plasmid DNA representing 3 ugs of DNA was added to 100 uls MT3568 protoplasts. 250 ul of 60% PEG solution was added and the tubes were gently mixed and incubate at 37° for 30 minutes. The mix was added to 10 ml of pre-melted Cove top agarose (The top agarose melted and then the temperature equilibrated to 40 C in a warm water bath before being added to the protoplast mixture). The combined mixture was then plated on two Cove-sucrose selection petri plates with 10 mM acetamide. The plates are incubated at 37° C. for 4 days. Single Aspergillus transformed colonies were identified by growth on the selection Acetimide as a carbon source. Each of the four A. oryzae transformants were inoculated into 750 μl of YP medium supplemented with 2% glucose and also 750 μl of 2% maltodextrin and also DAP4C in 96 well deep plates and incubated at 37° C. stationary for 4 days. At same time the four transformants were restreaked on COVE-2 sucrose agar medium.

Culture broth from the Aspergillus oryzae transformants were then analyzed for production of the SEQ ID NO 1 polypeptide by SDS-PAGE using NUPAGE® 10% Bis-Tris SDS gels (Invitrogen, Carlsbad, Calif., USA) according to the manufacturer. Two bands at approximately 97 kDa and 45 kDa were observed for each of the Aspergillus oryzae transformants. One A. oryzae transformant producing the SEQ ID NO 1 polypeptide was selected and was cultivated in 1000 ml Erlenmeyer shake flasks containing 100 ml of DAP2C medium at 30° C. for 3 days with agitation at 150 rpm.

Using Aspergillus versicolor, Aspergillus deflectus, or Aspergillus egyptiacus, SEQ ID NO 2, 3, and 4 were similarly cloned and expressed.

Cloning, Expression and Fermentation of Fungal SOD Enzymes

The SOD genes were derived from fungal strains isolated from environmental samples using standard microbiological isolation techniques. The donor strains HEAL7057, HEAL7058 and HEAL7059 were identified, and taxonomy assigned based on the DNA sequencing of the ITS (Table 1). The donor fungal organism for HEAL7007 was Trichoderma reesei QM6a, a publicly available strain originally isolated from the Solomon Islands and is available in collections such as ATCC (ATCC 13631).

Chromosomal DNA from individual strains was isolated by QIAamp Dneasy Kit (Qiagen, Hilden, Germany). 5 μg of each genomic DNA sample were sent for full genome sequencing using Illumina technology. Genome sequencing, the subsequent assembly of reads and the gene discovery (i.e. annotation of gene functions) is known to persons skilled in the art and the service can also be purchased commercially.

The genome sequences were BLAST analyzed for putative SOD from the PFAM database families PF00080. This analysis identified genes encoding putative SOD, which were subsequently cloned and recombinantly expressed in Aspergillus oryzae.

The SOD genes were amplified by PCR respectively from above isolated genomic DNA. The purified PCR products were cloned into the previously digested pDau109 by ligation with an IN-FUSION™ CF Dry-down Cloning Kit (Clontech Laboratories, Inc., Mountain View, Calif., USA) according to the manufacturer's instructions. The plasmid pDAu109 and its use are described in (WO 2005/042735). The ligation mixture was used to transform E. coli TOP10 chemically competent cells (described in Strains). The cloned genes were sequenced and confirmed to be identical to the corresponding genes found in the genome sequences and transformed into the Aspergillus oryzae strain MT3568 (WO 11/057140) by the methods described in Christensen et al., 1988, Biotechnology 6, 1419-1422 and WO 04/032648. Transformants were selected during regeneration from protoplasts based on the ability, conferred by a selectable marker in the expression vector, to utilize acetamide as a nitrogen source, and were subsequently re-isolated under selection.

Production of the recombinant SOD peptides was evaluated by culturing the transformants in 96-well deep-well microtiter plates for 4 days at 30° C. in either a 0.25 ml or 0.75 ml volume of either or both YPG medium (WO 05/066338) or DAP-4C-1 medium (WO 12/103350) and monitoring peptide expression by SDS-PAGE. A single Aspergillus transformant was selected for each gene based on expression yields as evaluated in microtiter plate fermentation.

Spores of the best expressed transformant were spread on COVE-2 plates for re-isolation in order to isolate single colonies. Then a single colony was spread on a COVE-2 tube until sporulation.

For larger-scale production of the recombinant enzymes, and the Aspergillus transformants were cultured in 500 ml baffled flasks containing 150 ml of fermentation medium. Transformants expressing the SOD peptides were fermented in DAP-4C-1 medium (WO 12/103350). The cultures were shaken on a rotary table at 150 RPM at for 4 days, and the broth was subsequently separated from cellular material by passage through a 0.22 um filtration unit.

Example 8 SOD Purification

The purification process for SOD was firstly applied with hydrophobic interaction chromatography, then if needed, ion exchange chromatography was applied. The difference for all the molecules was buffer type, pH, and salt concentration.

The culture supernatant of recombinant SOD was firstly added by ammonium sulfate with a final concentration of 2.2M and loaded into Phenyl Sepharose High Performance (GE Healthcare) equilibrated with 20 mM Tris-HCl at pH7.0 with 2.2M ammonium sulfate added. A gradient decrease of ammonium sulfate concentration from 2.2M to 0 was set up as elution condition. The elution fractions and flow-through faction were assayed by SDS-PAGE. The SOD activity was determined by the relative activity method of the SOD activity assay kit from Sigma (Cat No. 19160) described as below.

If the purity of enzyme purified by first step was not good and contains several bands, ion exchange chromatography will be applied for further purification. The fractions with SOD activity were pooled together and dialyzed with 20 mM Tris-HCl at pH7.0, then loaded into a Mono Q or Capto Q column (GE Healthcare) equilibrated with 20 mM Tris-HCl pH7.0. A gradient increase of NaCl concentration from 0 to 1M with 20 mM Tris-HCl at pH7.0 was set up as elution buffer. The elution fractions and flow-through fraction were assayed for SDS-PAGE and SOD activity.

The fractions with enzyme activity were pooled together and then diafiltrated with 20 mM Tris-HCl at pH7.0. The protein concentration was determined by Qubit® Protein Assay Kit (Invitrogen, cat Q33212).

Example 9 SOD Activity Assay

SOD activity was determined using the relative active method of the SOD activity assay kit from Sigma (Cat No. 19160). 20 μl SOD with different dilution times by MQ water and 0.01% Triton X-100 was added into 200 μl WST solution (prepared as described for SOD activity assay kit), then 20 μl coupled enzyme solution from kit was added. The mixture was measured at 450 nm for 20 minutes at 37° C. (interval 40 sec, shake before first read). One slope could be created with mOD/min vs enzyme dosage, which could be set as standard curve for each SOD. Two commercial SODs from Sigma®, recombinant SOD bovine expressed in Escherichia coli (S9697) with 6108 U/mg EP and SOD from E. coli (S5639) with 10240 U/mg EP were set as specific activity reference.

Since the pH of WST working solution was about 10, the SOD activity at alkaline condition might be very low. The SOD activity assay was later adjusted by at pH7.8, which WST solution was replaced by Cytochrome C solution at pH7.8 (Cytochrome C, Sigma-Aldrich C7752). The Cytochrome C working solution contains 50 mM PBS at pH7.8, 0.1 mM EDTA, 0.01 mM CytoC, and 0.05 mM Xanthine (Sigma-Aldrich X0626). The absorbance of mixture was measured at 550 nm.

Example 10 Gastric Stability Assay of SODs

Gastric stability was assayed with artificial gastric juice as stress condition. 20 μl SOD with appropriate dilution was added into 180 μl stress buffer (100 mM NaCl, 0.0013M HCl at pH3.0). The stress buffer with pepsin was prepared by adding 1.11 mg/ml pepsin (from porcine gastric mucosa, P7000, Sigma, 474 U/mg). The mixture was incubated at 37° C. in thermomixer for 0, 15, 30, 45, 60, 90, and 120 minutes separately. 10 μl sample extracted from the mixture was added into 90 μl activity buffer (K₂HPO₄/KH2PO4 mixed with final concentration of 100 mM PBS at pH7.0) as stop mixture. Then 20 μl stop mixture was added into 200 μl WST solution (or CytoC solution at pH7.8), and finally 20 μl coupled enzyme solution from kit was added to measure absorbance. The absorbance was measured at 450 nm for Sigma SOD kit (or 550 nm at pH 7.8) for 20 minutes at 37° C. (interval 40 sec, shake before first read). The activity at pH7.0 without stress condition was set as reference, and the residual activity at stress condition (pH3.0, pH3.0+pepsin) compared with reference was calculated as relative stability.

As can be seen from the Table, the SODs of the invention are surprisingly gastric stable compared to conventional and commercial SODs.

Example 11 Thermal Stability Assay of SODs

Thermal stability was quantified utilizing nano differential scanning fluorimetry (nDSF). To adjust pH, the samples were diluted 10-fold in a buffer cocktail containing 50 mM 2-(N-Morpholin)ethansulfonsyre (MES), 50 mM glycine, 50 mM acetic acid, pH 3-11. Sample dilutions were conducted using a Hamilton Microlab STAR Liquid Handling System in 96-well microtiter plates and transferred to 384-well microplates. The nDSF experiments were conducted utilizing either a Prometheus NT.48 or Prometheus NT.Plex with autosampler from Nanotemper. With the Prometheus NT.48, the samples were loaded manually using single capillaries (PR-0002), while samples were loaded in the Prometheus NT.Plex using capillary chips (PR-A0002). The experiments were conducted from 20 to 95° C. with a temperature gradient of 3.3° C./min. The transition temperatures (T_m-values) were obtained from peak values derived from the first-derivative of the signal trace (350/330 nm fluorescence ratio or 330 nm fluorescence) using PR. ThermControl software.

Example 13: Catalase Activity Assay

The catalase from Bovine Liver (Sigma®, Enzyme Commission (EC) Number: 1.11.1.6, CAS Number: 9001-05-2, Molecular weight: 250 kDa) has an activity of 3524 U/mg EP. Catalase activity was determined by H₂O₂ reduction detected at 240 nm. Firstly, catalase was diluted with different dilution times by MQ water and 0.01% Triton X-100. 10 μl enzyme sample, 90 μl activity buffer (K₂HPO₄/KH₂PO₄ mixed with final concentration of 100 mM PBS at pH7.0) were added into 50 μl 0.2% H₂O₂ solution (30% H₂O₂ was diluted to 0.2% in activity buffer). The mixture was measured at 240 nm for 10 minutes at room temperature (interval 34 sec, shake before first read). The commercial catalase from Sigma®, catalase from bovine liver (C1345), was set as reference. This allows for the selection of the suitable enzyme dosage.

Example 14: Gastric Stability Assay for Catalase

Gastric stability was assayed with artificial gastric juice as stress condition. 100 catalase with appropriate dilution was added into 900 stress buffer (100 mM NaCl, 0.0013M HCl at pH3.0). The stress buffer with pepsin was prepared by adding 1.11 mg/ml pepsin (from porcine gastric mucosa, P7000, Sigma, 474 U/mg) as pH3+pepsin buffer, and also was incubated with 10 ul catalase. The mixture was incubated at 37° C. in thermomixer for 0, 30, 60 and 90 minutes separately. 10 μl sample extracted from the mixture was added into 90 μl activity buffer as stop mixture. Then 100 μl stop mixture was added with 50 μl 0.2% H₂O₂ solution to measure absorbance. The absorbance was measured at 240 nm for 10 minutes at room temperature (interval 34 sec, shake before first read). One slop could be calculated by OD vs min, which presents the activity. The activity at pH7.0 without stress condition was set as reference, and the residual activity at stress condition (pH3.0 or pH3.0+pepsin) compared with reference was calculated as relative stability.
