利用枯草杆菌降低甘油发酵原液中残糖浓度的研究

The Experiment of Using Bacillus subtilis for Reducing the Remaining Sugar Concentration in Original Glycerine Fermentation Solution

甘油发酵原液中的残糖浓度高达 3 0 %～ 5 0 % ,给后提取工作造成很大的困难。利用一株枯草杆菌 6 6 331,进行甘油发酵原液的二次发酵 ,使得残糖浓度降至 1 0 %以下 ,且甘油含量基本不变 ,有利于下一步的提取精制。

It is very difficult to extract glycerine for the remaining high sugar concentration(3.0%～5 0%) in original glycerine fermentation solution The original glycerine fermentation solution has been quadratic fermented using a Bacillus subtilis 66331 The result shows that the remaining sugar concentration has been decreased to 1 0%,while the remaining glycerine content has been unchanged This will be useful for the next refine
