Abstract
Hydrocarbon contamination of the natural environments is a global phenomenon that disrupts the food chain and balance of nature. The assessment of the potentials of the mixture of sewage sludge, biowastes and some indigenous bacteria isolates in degradation of hydrocarbon impacted environment (Bonny light crude oil and spent engine oil) was carried out in experiments conducted both in the laboratory and on a pilot scale, using a formulation of sewage sludge, fresh Cocoa Pod Husk (CPH), Cow Dung (CD) and cocultures of Pseudomonas aeruginosa and Alcaligenes faecalis. It was observed that bacterial isolates degraded most fractions of Total Petroleum Hydrocarbons (TPH) and Polycyclic Aromatic Hydrocarbons (PAHs) including BTEX (benzene, toluene, ethylbenzene and xylene). The biostimulation using sewage sludge, Cocoa Pod Husk and CD significantly (P < 0.05) influenced degradation of some hydrocarbon fractions in Bonny light. The bacterial inoculant enhanced PAHs reductions (64.9, 29.7 and 103.5 mg/kg) on 5%, 10% and 15% spent engine oil contamination levels, respectively. The decontamination potential of these isolates using wastes is an indication of their prospect as bioenhancers in bioremediation of hydrocarbon impacted environments.
