摘要
在台式发酵罐上研究了Candidaantarctic以豆油为碳源生产生物表面活性剂甘露糖赤藓糖醇脂 (MEL)的分批发酵动力学 ,考察了不同的植物油作为碳源对生产MEL的影响 ,发现精制豆油为最佳碳源 ;在分批发酵实验中发现 ,pH值对C .antarctica的MEL生产影响不大 ,豆油质量浓度过高对菌体生长有一定的抑制作用 .
The kinetics of batch fermentation with mannosylerythitol lipid(MEL) produced from soybean oil by Candida antarctica was studied in a 2 L fermentator. The experiment was conducted to find the effect of different triacylglycerols acting as carbon source on MEL production and thus soybean oil was selected as the optimum substrate. It showed that the influence of pH was not significant and high concentration of soybean oil somewhat inhibited the cells growth in batch fermentation.
