Abstract:A new bioremediation method for petroleum contaminated soil (PCS) using both fungi and bacteria was proposed and investigated using Glomus caledonium NW03 and Bacillus subtilis NW08, both of which were isolated from PCS of Petro China of Changqing (PCOC), Shaanxi, China. The removal of total petroleum hydrocarbon (TPH) by the mixture was higher than the sum of the individual removal obtained in the pure culture. It was demonstrated that the growth behavior of the inocula and the degradation of TPH were enhanced by the mix culture of both fungi and bacteria. The remediation via inoculating the fungal-bacterial consortium removed 92.6% of TPH in 60 days while the control experiment with the indigenous microorganisms removed 21.9%. Significant reductions of each petroleum composition were shown by chromatogram analysis in treated soil, while the alkane fraction with molecule chains longer than 28 C almost disappeared.
