| 摘 要： | 研究以一株从自然环境中分离得到的酿酒酵母GXAS—BT9作为发酵菌株，利用丙酮-丁醇发酵的废液作为乙醇发酵的配浆用水，进行乙醇发酵。结果表明，GXAS—BT9菌株的乙醇发酵产率随着废液比例的升高而增加，使用100％废液作为配浆用水，玉米粉和木薯粉作为原料的乙醇产率分别达到14．27％vol和14．26％vol，比对照分别提高了14．7％和9．6％。将丁醇发酵与乙醇发酵偶联起来，实现了水的循环利用，同时大大减少了污水的排放量。 |

| Abstract: | A Saccharomyces cerevisiae strain GXAS-BT9 separated from natural environment was used as fermenting strain and acetone-butanol fermentation wastewater was used as blending water for alcohol fermentation.The results showed that alcohol production rate increased with the increase of the proportion of wastewater,ethanol production rate increased by 14.7 %vol as corn powder used as raw materials and by 14.26 %vol as cassava powder used as raw materials,14.7 % and 9.6 % increase compared with constrast group.Th... |
