ABSTRACT

Biosurfactants are surface-active molecule produced by microorganisms and have several advantages over the chemical surfactants. The objective of this research was to obtain biosurfactant-producing bacteria from hydrocarbon contaminated soils from Barmer, diesel shed Jodhpur etc. to observe their biosurfactant activity through oil spreading test, emulsification test, haemolysis test and drop collapse assay. Overall, 14 isolates were screened for biosurfactant production. The result showed that 13 strains gave positive results on the screening tests and were determined as biosurfactant-producing bacteria. Details of the biosurfactant producing efficiency of various bacterial strains are described. The findings can be useful for removal of organic pollutants from oil contaminated areas.
