Abstract: The present invention comprises pretreating a lignocellulosic feedstock with acid at a pH between about 2.0 and about 3.5 to produce a composition comprising an acid pretreated feedstock. The acid pretreated feedstock is then enzymatically hydrolyzed with cellulases and ?-glucosidase. The glucose is fermented by microorganisms to produce a fermentation broth comprising the fermentation product, followed by recovery of the fermentation product. The steps of enzymatically hydrolyzing and fermenting are conducted at a pH below about 4.0.

Abstract: In one embodiment the instant invention generally pertains to a method for producing glucose for fermentation. The method comprises first treating a biomass comprising a lignocellulosic material with a mixture comprising SO2 and steam at reaction conditions sufficient to produce a composition mixture comprising cellulose suitable for enzymatic hydrolysis. Specifically, the temperature, residence time, and SO2 concentration may be selected by calculating a crystallinity index (CrI) of the biomass and using the calculated crystallinity index as an indicator of enzymatic hydrolysis rate. In this manner cellulose may be enzymatically hydrolyzed glucose for aerobic or anaerobic fermentation.
