| 摘 要： | 在纤维素降解过程中,通过化学的方法对纤维素原料进行预处理,可以大大的促进纤维素的降解。本试验对甜高粱秸秆采用了碱、酸二种处理方法,并初步研究了降解纤维素预处理的最佳条件。试验中采用了廉-爱农方法对样品中的糖量进行了测定。试验结果表明,经过预处理,显著提高了纤维素的水解性。预处理的最佳条件是：碱法25℃,碱溶液浓度为5%,预处理时间50h;酸法酸溶液浓度为1.5%,预处理时间5h。

| Abstract: | The experiment includes the separation and purification of yeast in two leavens, and the growth curve, sugar content, fermentation ability, lethal temperature in the fermentation process were determined. Our experiment in this study provides effective parameters for the future breeding of yeast and selection of leaven. The yeast strain was selected for the alcohol fermentation using sweet sorghum straw, and this study is the basic study for the construction of mutagenesis strain and gene engineering strain. |
