摘要 本文研究了Cu2+对拟威克酵母Wickerhamiella domercqiae Y2A槐糖脂产量和组成的影响,发现Cu2+不但能够提高槐糖脂的产量,而且能够改变槐糖脂的组成。当Cu2+含量为10 mg·L-1槐糖脂的产量达到152.25 g·L-1,比对照提高1.18倍。通过TLC,FT-IR,HPLC、LC-MS分析手段对槐糖脂的组成成分进行了分析,发现加入Cu2+后,内酯型槐糖脂含量降低而酸型槐糖脂含量增加。 The inifluence of Cu2 +affecting the composition and production of sophorolipids affected by Wickerhamiella domercqiae Y 2A. The yield of total sophorolipids was greatly increased when adding Cu2 +in the medium,the yield of total sophorolipids was about 152. 25 g·L- 1under10 mg·L- 1Cu2 +condition, which was 1. 18 times higher than that of control. TLC,FT-IR,HPLC and LC-MS were used to analyze the composition of sophorolipids from Cu2 +. The result showed that the quality ratios lactonic sophorolipids decreased when adding Cu2 +in the medium.
