MULTI-STAGE ENZYMATIC HYDROLYSIS OF LIGNOCELLULOSIC BIOMASS EMPLOYING AN OXIDOREDUCTASE WITH AN AA9 POLYPEPTIDE

摘要

The invention relates to processes of multi-stage hydrolysis where different enzyme compositions are added in at least two stages of hydrolysis. In a first stage, a first enzyme composition of one or more cellulolytic enzymes and at least one of an oxidoreductase and an AA9 polypeptide having cellulolytic enhancing activity is added, followed by a latter stage in which a second enzyme composition comprising one or more cellulases is added. Also provided are processes for obtaining hydrolysis products and fermentation products using processes of the invention.
