摘要：

Corn stover pretreated by green liquor was hydrolyzed for 24 h at an initial substrate concentration of 100 g/L and a fed-batch of 50 g/L substrate for 6 h and 12 h, respectively, and then simultaneously saccharified and fermented for 48 h. Ethanol with a mass concentration of 47.58 g/L and a yield with 0.42 g/g cellulose was obtained. As the corn stover was pretreated under the same condition for 72 h, and the mass concentration and the yield of ethanol were 48.57 g/L ethanol and 0.43 g/g cellulose, respectively. Compared to semi-simultaneous saccharification and fermentation based on pre-hydrolysis, the simultaneous saccharification and fermentation were suitable for the bioconversion of pretreated corn stover at high substrate loading. ©, 2015, Editorial Board of Chemistry and Industry of Forest Products.
