| Abstract: | A bacterial consortium, constructed from the oil contaminated soil, mainly consisting of Pseudomonas sp., together with fertilizing, rice husk application, and plowing, was used for the field in situ bioremediation of oil contaminated site in Jianghan Oil field, where the temperature and humidity are very suitable for bioremediation. The variation of total petroleum hydrocarbon, n-alkanes, and polycyclic aromatic hydrocarbons (PAHs) in the bioremediation process showed that more than 95% petroleum hydrocarbons could be efficiently removed. The composition analysis results demonstrated that n-alkanes with long carbon chain and PAHs with 5–6 rings were also degraded in the bioremediation process. |
