ENZYME COMPOSITIONS AND METHODS FOR THE IMPROVED ENZYMATIC HYDROLYSIS OF CELLULOSE |
摘要 |
A process for the enzymatic hydrolysis of cellulose to produce a hydrolysis product comprising glucose from a pretreated lignocellulosic feedstock and enzymes for use in the process are provided. The process comprises partially hydrolyzing an aqueous slurry of a pretreated lignocellulosic feedstock with cellulase enzymes, one or more than one &bgr;-glucosidase enzyme and a binding agent for binding the &bgr;-glucosidase enzyme to fiber solids present in the aqueous slurry. The unhydrolyzed fiber solids are then separated from the hydrolyzed slurry. The separated fiber solids thus obtained are then re-suspended in an aqueous solution to produce a re-suspended slurry. The hydrolysis is then continued to produce the hydrolysis product comprising glucose. |
