Kinetics of hydrocarbon extraction from oil shale using biosurfactant producing bacteria

This study was done to extract hydrocarbon compounds from El-Lajjun oil shale using biosurfactant produced from two strains Rhodococcus erythropolis and Rhodococcus ruber. The results have shown that, optimal biosurfactant production was found using naphthalene and diesel as a carbon source for R. erthropolis and R. ruber, respectively. Optimum nitrogen concentration was 9 g/l and 7 g/l for R. erthropolis and R. ruber, respectively. Optimum...
