摘　　要：以秸秆为原料生产燃料乙醇是生物质燃料领域研究比较广泛的话题,玉米秸秆在我国北方产量较大,其主要成分是纤维素,半纤维素和木质素,利用菌株代谢能够使其水解产生的葡萄糖和木糖共同发酵生成乙醇,提高乙醇得率。通过实验对比,探究确定菌株发酵最适底物浓度。The production of ethanol from straw as raw material has been studied in the field of biomass fuel. The corn straw has a large yield in the north of China. Its main components are cellulose, hemicellulose and lignin. Using the strain metabolism, the glucose and xylose produced by hydrolysis can be fermented to produce ethanol, which improves the ethanol yield. Through the experimental comparison, the optimum substrate concentration was determined.
