摘要
文章研究了以新鲜马铃薯为底物,利用丙酮丁醇梭菌GX01发酵生产丙酮丁醇。对发酵培养基的组成进行了优化,确定了发酵培养基的组成:初始糖为90 g/L、豆粕为4.0 g/L和FeSO4.7H2O为0.08 g/L;以此发酵培养基在37℃下发酵60 h,丁醇产量平均可达到17.02 g/L,总溶剂量达到29.39 g/L。
Acetone and butanol fermentation by Clostridium acetobutylicum GX01 using fresh potato as fermentation substrate was studied.The fermentation condition was optimized.The research results showed that the optimum fermentation condition was： the initial concentration of sugar is 90 g/L,the soybean meal is 4.2 g/L,the FeSO4.7H2O is 0.08 g/L,the fermentation temperature was 37 ℃,and the fermentation time was 60 h.The yield of butanol and total solvent under the optimum condition were 17.02 g/L and 29.39 g/L,respectively.
