title: Enhancement of oil degradation by co-culture of hydrocarbon degrading and biosurfactant producing bacteria.
abstract: In this study the biodegradation of oil by hydrocarbon degrading Pseudomonas putida in the presence of a biosurfactant-producing bacterium was investigated. The co-culture of test organisms exhibited improved degradation capacities, in a reproducible fashion, in aqueous and soil matrix in comparison to the individual bacterium culture. Results indicate that the in situ biosurfactant production not only resulted in increased emulsification of the oil but also change the adhesion of the hydrocarbon to cell surface of other bacterium. The understanding of interactions beetwen microbes may provide opportunities to further enhancement of contaminants biodegradation by making a suitable blend for bioaugmentation.
