| 摘 要： | 本试验以有一定纤维素酶活力的黑曲霉Ａ．ｎｉｇｅｒＨＳ－００为出发菌株，经紫外光、激光、亚硝基胍复合诱变，选育出糖化稻草纤维素性能优良的Ａ．ｎｉｇｅｒＨＳ－１６菌株，其分解稻草纤维素产生还原糖的能力是出发菌株的５倍，还原糖生成率可达２８％。利用其稻草纤维素糖化液进行酒精发酵，酒化率为８４．８％。本试验还系统研究了影响稻草纤维素糖化的因素，确定了糖化用固体稻草培养基的最佳配方，分析了不同营养对酒精发酵

| Abstract: | The start strain of A.niger HS-00 with some cellulase activity was mutated multiply by UV-ray, laser and nitrosoguanidine, then a strain of A.niger HS-16 with high saccharifying activity of cellulose was obtained, Its capability of hydrolyzing straw cellulose to produce reducing suger was 5 times higher than that of the start strain. It could accumulate 28%reducing suger in saccharifying liquor. Using the saccharifying filtrate for alcohol fermentation,the efficiency of alcohol fermentation was 84.4%. Effect factors on saccharification, alcohol fermentation and the optimal proportion of straw medium were also studied. |
