摘要

"CELLULOLYTIC AND HEMICELULYTIC ENZYME PRODUCTION PROCESS, USING THE ETHANOLIC FERMENTATION WASTE OF ENZYMATIC HYDROLYSIS (CELULOSTIC MATERIALS"). The present invention relates to a process for producing cellulolytic and / or hemicellulolytic enzymes which utilizes the residue from ethanolic fermentation of enzymatic hydrolysates of cellulosic or lignocellulosic materials comprising the following steps: 1) chemical and / or physical pretreatment of a cellulosic or lignocellulosic substrate; 2) enzymatic hydrolysis of the pretreated substrate using celluiolitic and / or hemiceluiolitic enzymes; 3) ethanolic fermentation by an appropriate alcoholic microorganism of the hydrolyzate from step (2) and obtaining a fermentation must; and 4) separating the alcoholic microorganism used in step (3), separating / purifying ethanol and obtaining an aqueous phase which constitutes a residue; and wherein this residue serves to produce the cellulolytic and / or hemicelluolytic enzymes used in step (2).
