A STUDY ON CONVERSION OF CELLULOSlC BIOMASS TO ETHANOL
转化纤维素资源生成酒精的研究

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.
