摘要
对稻草秸秆高温预处理条件进行优化,以提高酶解还原糖得率为目的,探讨了高温预处理时固液比、pH、温度、时间对还原糖得率的影响。通过采用单因素多水平和正交实验方法得到最优预处理条件:固液比为1∶8,pH为12,温度为190℃,时间15min。在此最优条件下,酶解后的还原糖得率为88.97%。
Rice straw pretreatment in high temperature conditions were optimized to improve the enzymatic hydrolysis yield of reducing sugar. The effect of so))d-liquid ratio, pH,temperature,time to the sugar yield were investigated. By multilevel of single-factor test and orthogonal test methods,the results for the optimal pretreatment conditions were as follows:the solid-liquid ratio of 1:8,pH12,190℃, 15min. Under the optimal condition,the reducing sugar yield was 88.97% after enzymatic hydrolysis .
