    摘要: The present invention relates to an enzyme blend composition comprising a glucoamylase, an acid stable alpha amylase, and an acid fungal protease. The present invention is further directed to a method for producing end products such as alcohols from fermentable sugars, comprising the steps of: (a) contacting a slurry comprising a milled grain that contains starch with an alpha amylase to produce a liquefact; (b) contacting the liquefact with a glucoamylase, an acid stable alpha amylase, and an acid fungal protease, to produce fermentable sugars; and (c) fermenting the fermentable sugars in the presence of a fermenting organism to produce end products.
