摘要： A method for degrading or converting a cellulosic material is provided, comprising (a) subjecting the cellulosic material to an enzyme composition at a mild agitation with low rotation speed; and (b) subjecting the cellulosic material to an enzyme composition at a sufficient agitation with high rotation speed. A method for producing a fermentation product is further provided, comprising (a) saccharifying the cellulosic material with an enzyme composition at a mild agitation with low rotation speed; (b) saccharifying the cellulosic material with an enzyme composition at a sufficient agitation with high rotation speed; and (c) fermenting the hydrolyzed cellulosic material with one or more fermenting microorganisms to produce the fermentation product.
