Study on Biosurfactants Producing Fungus Isolated From Oil Contaminated Soil
Abstract
Microorganisms produce biosurfactantsthat are biologically safe. They are useful in various biological process. Biosurfactant producing microorganisms are naturally present in oil-contaminated soil. In this study, we have isolated biosurfactant-producing fungi from oil-contaminated soil. Biosurfactantswere extracted from the isolated fungi and were characterized using various techniques. The biosurfactant had maximum activity at pH 8 and emulsification index of 30%. The maximum yieldof biosurfactant wasin the 7 days at 37
