| 摘 要： | 研究了高温厌气的热纤梭菌(Clostridium thermocellum)转化纤维素物质直接生成酒精的过程,发酵产物除酒精外,还有乙酸、少量乳酸、H_2、CO_2和还原糖,还原糖的主要成份为木糖,纤维二糖和葡萄糖、诱变菌转化纤维素的能力与野生菌相比有明显提高,能发酵细小纤维、稻草和凤眼莲,酒精最大浓度可分别达4.0,3.2和9.3g/L。

| Abstract: | A process of direct conversion of cellulosic biomass to ethanol by a thermophilic, anaerobic bacterium Clostridium thermocellum was evaluated. Besides ethanol, acetic acid, lactic acid, hydrogen,carbon dioxide and reduced sugar were produced. The main composition of the reduced sugar are xylose, cellobiose and glucose. The ability of cellulose degradation by the mutant is obviously higher than that of the wild.The mutant can ferment fine fibril, rice straw and Eichhornia Crassipes, the maximum concentration of ethanol was found to be 4.0, 3.2 and 9.3g/l, respectively. |

| Keywords: | clostridium thermocellum cellulosic biomass ethanol fermentation. |
