Abstract
Feasibility study carried out at the site prior to the full scale study showed that the introduced bacterial consortium effectively adapted to the local environment of the soil at bioremediation site The soil samples were collected from the contaminated fields after treatment with bacterial consortium at different time intervals and analyzed by gas chromatography after extraction with hexane and toluene At time zero just before initiation of bioremediation the concentration of total petroleum hydrocarbons in the soil 25cm horizon of plot A B C and D was 3090 1880 2590 and 2990 respectively after 360 days of treatment with microbial consortia was reduced to 097 10 10 and 11 respectively Whereas only 5 degradation was observed in the control plot after 365 days microbial consortium not applied
