发酵抑制物对葡萄糖发酵产乙醇的影响
Effects of fermentation inhibitors on ethanol production of glucose fermentation
摘要
Abstract
In pretreatments of lignocellulosic materials for bioethanol production,certain amount of sugars was degraded as fermentation inhibitors,and the degradation was much more severe in the acidic pretreatment.Theses fermentations inhibitors including formic acid, acetic acid, levulinic acid,furfural,and 5-hydroxymethylfurfural (HMF)which affect the conversion yield of ethanol from glucose fermentation.This paper examined the effect of the five fermentation inhibitors concentration on the ethanol yield of Saccharomyces cerevisiae glucose fermentation. The results show that, synergistic effect of various fermentation inhibitors on ethanol fermentation was higher than single fermentation inhibitor on ethanol fermentation.The total fermentation inhibitors in fermentation solutions generally controlled within 3.0g/L,which inhibitory effect on glucose fermentation for ethanol is not obvious.关键词
