METHOD FOR THE PRODUCTION OF A FERMENTATION PRODUCT FROM LIGNOCELLULOSIC FEEDSTOCKS |
摘要 |
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 ß-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 4Ø
