用活性炭对蒸气爆破尾叶桉木材的纤维素酶水解液进行脱色,脱去其中的糠醛和酚类等发酵抑制物,对于水解液的发酵是有利的。研究采用正交试验法,以脱色率和总还原糖回收率为主要指标,对水解液的活性炭脱色工艺中的温度、pH、脱色时间、活性炭用量等进行了研究,确定了最佳的脱色条件:温度70℃、pH2、脱色时间90min、活性炭用量3.5%。在该条件下水解液的脱色率达到(77.02±0.52)%,总还原糖回收率为(80.81±0.23)%。 It is beneficial for the fermentation of hydrolyzate to decolorize the cellulase hydrolyzate of Eucalyptus urophylla by steam explosion and remove the fermentation inhibitors such as furfural and phenols. The orthogonal experiment was used to study the decolorization rate and the total sugar recovery rate. The optimum conditions of decolorization, such as temperature, pH, decolorization time and the amount of activated carbon, were studied. : Temperature 70 ℃, pH2, decolorization time 90min, the amount of activated carbon 3.5%. Under these conditions, the decolorization rate of hydrolyzate reached 77.02 ± 0.52%, and the total recovery rate of reducing sugar was (80.81 ± 0.23)%.
