Biosurfactants are surface active compounds produced by microorganisms. The objective of this study is to isolate and identify the biosurfactant producing bacteria from oil contaminated soil. The 5 organisms were selected to determine the ability to produce biosurfactant. The organisms identified were Bacillus sp (B1), Bacillus sp (B2), Pseudomonas sp (B3), Micrococcus sp (B4), Klebsiella sp (B5).. From the screening test such as hemolytic assay, oil spreading assay and lipase assay, all the 5strains were showed positive results. Diesel degradation studies using organisms has found to be able to degrade the diesel oil of different concentrations.
