Abstract : Biosurfactants are surface active molecules produced by various organisms, which have beneficial in structural diversity, low toxicity and biodegradability. These properties makes these compounds for a variety of potential applications, including cosmetics– pharmaceutical formulations, agricultural, food industry, oil recovery and environment protection technology. Furthermore, the biological properties of biosurfactants have also augment interest of industrial application. Biosurfactants are grouped into three categories of origin: microbial derived, animal-derived and plant-derived biosurfactants. In this study it is possible to isolate two bacterial strains which produce biosurfactants, from two very cheaper resources - oil contaminated soil and sewage water. The bacterial strains were tested for the ability to produce biosurfactants and screened for biosurfactant activity by oil displacement method. The highest biosurfactant producing strains were selected and identified by microscopic appearance and biochemical activities. The extracted biosurfactant’s emulsification activities were compared with synthetic surfactants. Simultaneously the biosurfactant produced by these strains were tested for its antibiofilm activity against various pathogenic microbes and found to have significant antibiofilm activity. The beneficial property ofnbsp; biosurfactant productionnbsp; make the strains an efficient bioremediation tool for various environmental application and represent greater significance in future biomedical applications.
