| Summary: | The present paper deals with the treatment of oil spills using weights of modified lignocellulose sawdust. The crude oil sorption on the surface of sawdust was discussed. Nineteen crude oil-degrading bacterial isolates were separated from an oil-polluted area in Saryaqos, Al-kanakah and Mustorud area, Egypt. Four bacterial species showed the predominated growth rate on crude oil hydrocarbons. The effect of the different weight of sawdust (0.1–0.5 w/v) on the bacterial degradation of the crude oil sample was investigated. Biodegradation potential was evaluated after 5 days. The total oil was removed from the microcosms after the biological treatment ranging from 65 to 80% after 5 days. Gas Chromatographic (GC) analysis of the crude oil remaining in the culture medium, showed that the higher biodegradation of isoparaffins than n-paraffins in microcosms containing biosurfactant, the higher weight of fatty sawdust (FSD) at 0.5 g and BI1, BI4 and a bacterial consortium of four bacterial isolates separately. The result shows that these bacterial strains can be used for the bioremediation using modified sawdust in oil-polluted area. Keywords: Bioremediation, Pollution, Oil Spill, Sorption, Sawdust |
