Isolation and Characterization of Petroleum Hydrocarbon Degrading Bacteria from the Bohai Sea, China

Fourteen petroleum hydrocarbon degrading bacteria strains were isolated from oil-contaminated site. Isolated strains were able use diesel oil as sole carbon and energy source. Bacterial strain HD1 was selected due to the luxuriant growth on oil agar. The oil degradation rate of strain HD1 was analyzed using UV-spectrometry-based methods. The result showed that the rate of diesel oil degradation of 75% was observed after 14days of cultivation.
