Industrial waste and sewage pollute more than 2/3 of India’s water resources. Stream pollution isa serious and growing problem in most developing countries where there is little waste water treatment.Increasing contamination of aquatic resources with pollution including heavy metals (like chromium, lead,cadmium, zinc, nickel etc.) endangers aquatic biota and declines water quality. Bioremediation is a processthat uses microorganisms or their enzymes to return the environment altered by contaminants to its originalcondition. Biological methods for the removal of heavy metals from industrial waste may provide anattractive alternative to the physico-chemical process; biosurfactants are one of the compounds that aid inalleviating the heavy metals. Microorganisms while trying to utilize substrates like hydrocarbon as carbonsource facilitate the diffusion into cell by producing a variety of substances called biosurfactants. Severalmicrobes such as Bacillus sp., Pseudomonas sp., Acinetiobacter sp. and Arthobacter sp. are reported toproduce biosufactants. Compared to synthetic compounds, biosurfactants offer the advantages of little or noenvironmental impact and the possibility of in situ production. Studies in recent past have demonstrated thesuccessful use of biosurfactants for facilitating the degradation of organic pollutants in soil and water. In thelight of above the present study is aimed to carry out the assessment of efficiency of biosurfactants(Rhamnolipid) producing microorganisms (Pseudomonas sp.) isolated from heavy metal contaminated site. |
