Biodegradation of crude oil in seawater using a mixture of oil and heterotrophic bacteria

Abstract

This project aims to enhance oil biodegradation in seawater. Retardation of crude oil biodegradation in seawater is hypothetically due to the inhibiting metabolites produced by the oil bacterium which inhibit its enzymes. For this purpose, the consortium bacteria with an active oil-oxidizing bacterium (AR3) and two oil-resistant and active heterotrophic bacteria (OG1 and OG2) was formed. Heterotrophic bacteria, OG1 and OG2 were able to remove metabolites produced during oil degradation.
