Abstract

Background: Biodegradation of hydrocarbon compounds is a great environmental concern due to their toxic nature and ubiquitous occurrence. In this study, Biodegradation potential of oily soils was investigated in an oil field using Indigenous bacterial consortium. Methods: The bacterial strains present in the contaminated and non-contaminated soils were identified via DNA extraction using 16S rDNA gene sequencing during six months. Furthermore, Total petroleum hydrocarbons (TPH) were removed from Oil-contaminated soils. The TPH values were determined using a gas chromatograph equipped with a flame ionization detector (GC-FID). Results: The bacterial consortium identified in Oil-contaminated soils (case) belonged to the families Halomonadaceae (91. 5%) and Bacillaceae (8. 5%), which was significantly different from those identified in non-contaminated soils (control) belonging to the families Enterobacteriaceae (84. 6%), Paenibacillaceae (6%), and Bacillaceae (9. 4%). It was revealed that the diversity of bacterial strains was less in Oil-contaminated soils and varied significantly between case and control samples. Indigenous bacterial consortium was used in Oil-contaminated soils without need for amplification of heterogeneous bacteria and the results showed that the identified bacterial strains could be introduced as a sufficient consortium for Biodegradation of Oil-contaminated soils with similar texture, which is one of the innovative aspects of this research. Conclusion: An oil-contaminated soil sample with TPH concentration of 1640 mg/kg was subjected to bioremediation during 6 months using Indigenous bacterial consortium and a TPH removal efficiency of 28. 1% was obtained.
