| Abstract: | Effects of degradation products of carbohydrates on the fermentation of Saccharomyces cerevisiae and the fermentation of corn stover enzymatic hydrolysate were investigated.The inhibition strengths of the typical inhibitors to ethanol fermentation were in the order of: formic acid>acetic acid>furfural>hydroxymethylfurfural(HMF).For ethanol fermentation,S.cerevisiae NLH13 could tolerate 1g/L formic acid and 4g/L acetic acid,respectively.However,S.cerevisiae NLH13 displayed higher tolerance to furfural and hy... |
