Abstract
The chemical analysis and surface chemical properties of biosurfactant formed by Rhodococcus sp. strain IGTS8, which is widely used in biodesulfurization process, in hexadecane/water mixture have been studied. For the chemical analysis, TLC technique was employed. The surface tension, CMC, and emulsion stability of biosurfactant solution were also investigated. The major components of biosurfactant formed by Rhodococcus sp. strain IGTS8 were glucose mycolate and trehalose monomycolate. The CMC of aqueous biosurfactant solution was 0.1 ~0.15 g/100 mL of Water at pH 6.0-6.5 and pH 10~10.5. But the demulsification was faster at pH 10 than at pH 6.3.
