| Abstract: | A yeast strain, Wickerhamiella domercqiae Y_ 2A, producing sophorolipids was isolated from oil-contaminated wastewater. The medium compositions and fermentation conditions were optimized by single factor and orthogonal experiments. Medium: 8.0% glucose, 8.0% rapeseed oil and 0.3% yeast extract; Fermentation conditions: initial pH 6.0 and 2.5 % of inoculation volume. The yield of sophorolipids was 41.3 g L -1 for 120 h of fermentation. Fig 4, Tab 5, Ref 16 |
