摘　　要：为得到糖化降解甜高粱秸秆最优的条件,甜高粱秸秆进行NaOH处理后,利用多种分解纤维素的菌种进行混合发酵。结果发现,白腐菌、黑曲霉和康宁木霉组合发酵NaOH处理过的秸秆,其降解率最高,糖化率达到3.19mg/mL。In order to obtain the best fermentation efficiency , Several species of fungi with high cellulase activity were cultivated in sweet sorghum stalk which was hydrolyzed by NaOH. The results showed that the mixed strains of Phanerochaete chrysosporium,Aspergillus niger and Trichoderma koningii in the hydrolyzed sweet sorghum stalk could achieve the highest degradation efficiency and its sugar concentration was 3.19mg/mL.
