The present invention provides nucleotide sequences of Macrophomina phaseolina (“M. phaseolina”) that encodes proteins/enzymes with cellulolytic activity, including a cellulase activity, a endoglucanase, a cellobiohydrolase, a β-glucosidase, a a-glucosidase, a xylanase, a mannanse, a β-xylosidase, a a-xylosidase, a galactosidase, an arabinofuranosidase, a a-fucosidases, a β-galactanase, an unsaturated β-glucuronyl hydrolase and/or oligomerase activity. Vectors, expression constructs and host cells comprising and/or consisting of the nucleotide sequences of the enzyme genes are also provided. The invention further provides methods for producing the enzymes and methods for modifying the enzymes in order to improve their desirable characteristics. The enzymes of the invention can be used in a variety of, but not limited to, pharmaceutical, agricultural, food and feed processing, biofuel, energy efficiency and industrial contexts. These enzymes are also useful for complete hydrolysis of lignocellulosic biomass into simple sugar that can then be fermented to liquid fuels and chemical feedstocks.

The present invention relates to transgenic microalgae for the production of cell wall degradative enzymes having a heat-stable cellulolytic activity (HCWDEs) and their relative uses in the biodegradation of cellulose or lignocellulose sources in the industrial field.

The present invention relates to a leader peptide which promotes the secretion of recombinant proteins and a nucleic acid sequence encoding the leader peptide as well as expression cassettes, vectors and host cells comprising this leader sequence. Also disclosed is a method for producing a protein using this leader peptide.

The present invention is directed to a yeast strain, or strains, secreting a full suite, or any subset of that full suite, of enzymes to hydrolyze corn starch, corn fiber, lignocellulose, (including enzymes that hydrolyze linkages in cellulose, hemicellulose, and between lignin and carbohydrates) and to utilize pentose sugars (xylose and arabinose). The invention is also directed to the set of proteins that are well expressed in yeast for each category of enzymatic activity. The resulting strain, or strains can be used to hydrolyze starch and cellulose simultaneously. The resulting strain, or strains can be also metabolically engineered to produce less glycerol and uptake acetate. The resulting strain, or strains can also be used to produce ethanol from granular starch without liquefaction. The resulting strain, or strains, can be further used to reduce the amount of external enzyme needed to hydrolyze a biomass feedstock during an Simultaneous Saccharification and Fermentation (SSF) process, or to increase the yield of ethanol during SSF at current saccharolytic enzyme loadings. In addition, multiple enzymes of the present invention can be co-expressed in cells of the invention to provide synergistic digestive action on biomass feedstock. In some aspects, host cells expressing different heterologous saccharolytic enzymes can also be co-cultured together and used to produce ethanol from biomass feedstock.

Disclosed is a method for improving the yield of sprayed corn bran in a corn wet-milling process, an enzyme preparation is added in the process of separating fiber from starch and protein, the fiber residue after the enzyme preparation treatment contains less water, less starch and/or protein residue, and has a looser and more fluffy structure, the yield of the sprayed corn bran in the corn wet-milling process can be remarkably improved while ensuring normal color of the finished sprayed corn bran, that is, the amount of concentrated corn soaking solution sprayed on the fiber corn bran is significantly increased.
