摘要
以稻草作为碳源、污泥作为氮源,利用绿色木霉(Trichoderma viride)和酿酒酵母(Saccharomyces cerevisiae)降解稻草转化为乙醇,并对该过程中影响乙醇产量的因素进行优化。结果表明,当预处理稻草与预处理污泥质量比为1∶10(g∶g)、降解培养基初始p H值为7、绿色木霉和酿酒酵母的接种量分别为4%和3%、降解温度为37℃和降解时间为48 h时,可得到乙醇的含量为49.25 mg/L。
Rice straw and sludge were used as carbon source and nitrogen source respectively, rice straw were degraded to ethanol by Trichoderma viride and Saccharomyces cerevisiae. The factors affecting ethanol yield in degradation were optimized. The results showed that the highest ethanol concentration was 49.25 mg/L, under the conditions of the pretreated rice straw and sludge mass ratio 1：10（g：g）, initial pH of degradation medium 7, T. viride and S. cerevisiae inoculum 4% and 3%, degradation temperature 37 ℃ and time 48 h.
