IMPROVED METHOD OF PRODUCING CELLULASE AND/OR HEMICELLULASE ENZYMES Russian patent published in 2015 - IPC C12N9/24 C12N9/42 C12P1/02 C12P7/10 C12P19/00 C12R1/885 

FIELD: technological processes.

SUBSTANCE: invention relates to biotechnology and can be used for hydrolysis of lignocellulosic biomass. A method of producing cellulase and/or hemicellulase enzymes of Trichoderma ressei includes at least one step for growth in the presence of a carbon substrate selected from glucose, xylose, lactose, residues obtained after ethanol fermentation of monomeric sugars of enzymatic hydrolysates of cellulosic biomass and/or raw extract of water-soluble pentoses and at least one step for production in the presence of an inducing substrate, wherein said inducing substrate is a mixture containing 40-65 wt % glucose or cellulose hydrolysates, 21-25 wt % lactose and 10-39 wt % xylose or solution of hemicellulose lignocellulose hydrolysate, wherein the sum of said three components is equal to 100%.

EFFECT: method increases output of enzymes.
