Method for producing cellulosic ethanol by fermenting cysticercus tannophilus and saccharomyces cerevisiae

The invention belongs to the technical field of cellulosic ethanol production, and relates to a method for producing cellulosic ethanol by fermenting cysticercus tannophilus and saccharomyces cerevisiae. The method comprises the following steps of: strain selection: selecting directionally domesticated cysticercus tannophilus and saccharomyces cerevisiae strains; slant culture, seed propagation, fermentation culture, and direct distillation of fermentation liquor to obtain ethanol. Compared with the prior art, the method provided by the invention has the advantages that glucose and xylose are simultaneously utilized, the utilization rate of xylose is effectively improved, and the utilization rate of straw raw materials is improved. 本发明属于纤维乙醇生产的技术领域，涉及一种利用嗜鞣管囊酵母和酿酒酵母混合发酵生产纤维质乙醇的方法。包括以下步骤菌种选择：选用经定向驯化的嗜鞣管囊酵母和酿酒酵母菌株；斜面培养、种子培养、种子扩培、发酵培养、直接取发酵液蒸馏获得乙醇。本发明于现有技术相比葡萄糖木糖同时利用，有效提高木糖利用率，提高了秸秆原料利用率。
