| Abstract: | 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）. |
