摘要：以木糖纯种发酵菌种的筛选为基础,得到了能发酵木糖的混合菌群。将该菌群进行了稀酸预处理液发酵的筛选驯化,得到能发酵稀酸预处理液的菌群B00。与纯种发酵对比,混合菌种发酵有较广的初始pH值、温度、摇床转速的适应范围以及较广的底物应用范围和较强的发酵抑制物耐受性,因而更适合工业化的应用;在木糖含量为30 g/L、葡萄糖含量为15 g/L的稀酸预处理液中,该混合菌种的最高乙醇产量为15.8 g/L,产率为68.9%,高于纯培养的乙醇产率62.6%。
Mixed bacteria of fermenting xylose could ferment xylose,Through the isolation and was obtained based on the pure isolation which domestication of dilute-acid pretreated solution, mixed bacteria BOO which could ferment the dilute-acid pretreated solution was obtained.When the glucose was 15 g/L, xylose was 30 g/L in the solution, the maximum ethanol production of BOO was 15.8 g/L and 68.9%, which 62.6% higher than the pure cuhure. Compared to the pure culture ,mixed bacteria flora had a greater range of initial pH, temperature, shaker speed, carbon sources and fermentation inhibitors tolerabilitv, which made them more suitable for industrial applications.
