Abstract: | Candida antarctica synthesised surface-active mannosylerythritol lipids at 46 g l–1 by adding 80 g soybean oil l–1 to the medium and maintaining the pO2 at 50% with an air flow rate 1 vvm. Two-stage culturing of C. antarctica avoided medium foaming but the yield of biosurfactants synthesis was 28 g l–1. The biosurfactants decreased the surface tension of water to 35 mN m–1. |
