Cleaning compositions may include a mix of enzymes that include a dispersin and a carbohydrase. Said compositions may be used in cleaning processes and/or for deep cleaning of organic stains.

A method of producing saccharides, in which fluidity of the slurry including biomass can be retained; the used amount of the degrading enzyme can be reduced; and high concentration saccharides can be produced, is provided. In addition, a method of producing ethanol, in which high concentration ethanol can produced, is provided. The method of producing saccharides includes the steps of: adding a cellulose degrading enzyme to a slurry including a biomass; and degrading the cellulose included in the biomass by the degrading enzyme to produce saccharide including glucose as a major component. The concentration of the cellulose is retained at 75 g/L or less in a mixed solution including the slurry, the degrading enzyme, and an adsorption inhibitor inhibiting adsorption of the degrading enzyme to a lignin contained in the biomass.

The present invention relates to compositions to induce production of proteins, e.g., enzymes, e.g., amylases or biomass degrading enzymes in a host cell, and methods for increasing the yield of the proteins, e.g., enzymes produced. Such compositions comprise a caramelized sugar product. The methods described herein can also be used to enhance processing of biomass materials, e.g., to produce sugar products.

Disclosed is variants of a cellulase having improved stability in the presence of a protease, and the use of such variants in laundry.

The present invention relates to enzyme compositions for high temperature saccharification of cellulosic material and to uses thereof.

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.

The invention relates to a strain of fungus having a reduced viscosity, wherein the ID 78713 (GEL3) gene has been invalidated. The invention also relates to the different uses of this strain, as well as to the method of genetic modification.

The invention relates to a process for the preparation of colchicine 1 from colchicoside 2 which comprises enzymatic conversion of colchicoside 2 to 3-O-demethylcolchicine 3, wherein the enzyme used is a cellulase. According to another aspect of the invention, 3-O-demethylcolchicine 3 can be converted to colchicine 1 using an alkylating agent. The invention also relates to a process or enriching the colchicine 1 content of extracts from plants belonging to the Colchicaceae family containing colchicine 1, colchicoside 2 and 3-(9-demethyl colchicine 3, which comprises conversion by means of a colchicoside 2 cellulase to 3-O-demethylcolchicine 3, followed by conversion of 3-O-demethylcolchicine 3 to colchicine 1 using an alkylating agent.

A process for producing cellulolytic and/or hemicellulolytic enzymes with a strain of microorganism belonging to the family of filamentous fungi. The process includes growing the fungi in an aqueous culture medium, in the presence of at least one carbon-based growth substrate, in a stirred and aerated bioreactor. It also includes the production of enzymes, starting with the aqueous culture medium in the presence of at least one inductive carbon-based substrate and also inducing the production of hydrophobins. Further, at least a portion of the hydrophobins produced in step (b) are reintroduced into the growth step (a).

The present invention relates to xylanase variants of a parent xylanase having increased thermostability when compared to the parent xylanase. The present invention also relates to polynucleotides encoding the variants, nucleic acid constructs, vectors, and host cells comprising the polynucleotides, and method of producing the variants of the present invention.
