摘　　要：目的:探讨甘油预处理对稻草粉酶解效果的影响。方法:采用正交实验法,以液固比、甘油质量分数、甘油预处理时间为因素,考查对还原糖浓度的影响。结果:甘油质量分数为70%,液固比为20∶1,甘油预处理时间为3d时,其对应的还原糖浓度为297.34μg/m L。结论:甘油预处理方法对稻草粉酶解效果有较为显著的影响。Objective： To investigate the effect of pretreatment with glycerol solution effect on straw powder enzyme. Methods：With the extraction rate of reducing sugar,as the solid-liquid ratio,the mass fraction of glycerol,glycerol pretreatment timefactorsd and by using orthogonal test method. Concentration： The glycerol concentration was 70%,liquid-solid ratio is 20∶1,glycerol pretreatment time is 3d when the concentration of reducing sugar for the corresponding 297.34g/mL. Conclusion：Glycerol pretreatment methods have remarkable influence on the effect of straw powder enzyme.
