摘　　要：通过对纤维素酶水解糖化木薯秸秆工艺条件的优化,对纤维素酶水解糖化木薯秸秆的影响因素进行分析。结果表明,最佳反应条件为:在温度为45℃,反应体系pH为4.5,酶用量为2g/L,反应时间为42h,还原糖得率最大。Analysis of Influencing Factors on hydrolysis of cassava stalk to sugar with cellulase was studied by optimizing the technology conditions. The results showed that the best conditions of the preparation were： enzyme pH 4.5, temperature 45℃, enzyme concentration 2g/L, hydrolysis time 42h. Under the conditions, cassava stalk hydrolyzed by the enzyme could produce much more reducing sugar, and has the best effect.
