| Abstract: | Using of biosurfactant producing microorganisms for pipeline cleaning, bioremediation, enhanced oil recovery, etc. is a much soughed approach of petroleum industry. Although, many alternatives are available to serve these purposes, being ecofriendly and economic, microbial application is considered superior than most of the alternatives. This paper presents a comprehensive study on effectiveness of bacterial strain isolated from oil contaminated soil sample of Lakwa oilfield for required purposes. Its temperature sustainability and surfactant production capability was studied. Further characteristics of the produced biosurfactant were assessed through Emulsification Index measurement, Fourier Transform Infrared Spectra, Drop Collapse Test, Contact Angle and Viscosity measurement. |
