Abstract

Owing to their versatile properties, many biosurfactants are implicated in the cleanup of oil spills, heavy metals, and organopollutants. A number of biosurfactants have the potential to be used in the household detergent formulation as they are good stain remover and are quite compatible with enzymes and other additives used in detergents. This chapter presents an in-depth evaluation of the use of biosurfactants in bioremediation and in approaches for maintaining soil quality. However, many studies on the exogenous supplementation of biosurfactants in bioremediation showed the contradictory effect on biodegradation of pollutants. Hence, a thorough investigation of the efficacy and toxicity of biosurfactants is to be performed before implementing the biosurfactants in bioremediation. Biosurfactants can be a potential replacement to chemical surfactants only if they meet the large-scale production and cheap prices of synthetic surfactants. Use of inexpensive substrates, employing high yield strain, and developing cost-effective downstream processing are some of the approaches to reduce the cost of biosurfactants.
