摘　　要：Byssochlamys fulva AM130,a novel strain of filamentous fungus,could produce ethanol from glucose,xylose,and alkali pretreated rice straw(PRS),while the efficiencies were very low with PRS.Ethanol production of 11.84 g/L was attained by the fungus when grown in glucose,indicating that the limitations while growing on PRS were related to low hydrolytic efficiency.Enzyme profiling of the fungus showed 365 IU/ml of beta-glucosidase and 89 IU/ml of xylanase activity,while endoglucanase and filter paper activity were negligible,which accounts for the low hydrolytic efficiency.The fungus could survive for extended periods under oxygen-limited conditions and produce ethanol.The fungal mycelia could also be used for repeated cycles of anaerobic fermentation,wherein the ethanol yield improved with each consecutive cycle.
