Optimization of process conditions for biosurfactant production

Biosurfactants are surface active compounds produced by variety of microorganisms. It is a promising alternative to chemically synthesized surfactant due to it biodegradability, low toxicity, and environmental acceptability. However, commercialization of this product is yet to be realized due to hig...
