摘　　要：以玉米秸秆为原料,经酸法预处理后,采用同步糖化发酵SSF工艺生产燃料乙醇。正交试验获得的最佳体系为:培养温度34℃、发酵pH值5.5、发酵的液固比8:1、当发酵108h后,乙醇浓度可达8.33g/L。该实验为纤维质燃料乙醇的产业化生产提供技术依据。Fuel ethanol was produced by synchronization saccharification and fermentation（SSF）.The corn stalk was taken as raw materials pretreated with acid method.The optimum SSF condition was 34℃,for reaction temperature,5.5 for initial fermentation liquid pH value,solid to liquid ratio 1：8.After 108h,the ethanol concentration reach highest（8.33g/L）.
