In recent times river pollution is a serious and growing problem in most developing countries. Industrial effluents and sewage entering the water bodies are one of the major sources of environmental toxicity, which endangers aquatic biota and deteriorates water quality. Biological methods for the removal of heavy metals from industrial waste may provide an attractive alternative to the physiochemical process. Biosurfactants are one of the compounds that help in alleviating the heavy metals. A large number of bacteria such as Psudomonas sp , Bacillus sp, Acinetobacter sp, Arthrobacter sp are reported to produce biosurfactants. Compared to synthetic compounds, biosurfactants provide the advantages of little or no environmental impact and the possibility of in-situ production. Studies in recent past have exhibited the successful use of biosurfactants for facilitating the degradation of organic pollutants in soil and water. | Detoxification of heavy metals using microbial biosurfactant
