Environmental Assessment of Petrophilic Bacteria Associated with ‎Bioremediation and Biodegradation of Engine Oil Contaminated Soil in ‎Maiduguri

Soil contamination by petroleum hydrocarbons is a major problem resulting from activities related to industry, automobile service stations and accidental release of oil in the soil. Bioremediation/biodegradation can be considered as an effective aid clean up spills, aside conventional methods that are uneconomical produce residues harm surrounding biota. There estimated over 250 mechanic shops with more than 5000 technicians Maiduguri. Mechanics working therein frequently spill which potent source immunotoxicants carcinogenic humans animals. The aim this study was screen for petrophilic bacterial isolates engine contaminated soil, utilize crude sole carbon growth Maiduguri Metropolis. Ten soils Bola Tashan Kano areas Borno State were obtained. bacteria individually cultured Bushnell Haas Mineral Salt Medium devoid except 21 days at 370C. Bacterial visible increased turbidity enumerated CFU/g on nutrient agar. Pseudomonas sp. isolate exhibited relatively higher ability grow TNTC followed Bacillus sp., 6.7×104, Arthrobacter sp.,6.5×104, Flavobacterium sp.,6.2×104, 6×104, Nocardia sp.,5.9×104, Acinetobacter 5×104, 5×104. Proteus 4.7×104 4×104. It therefore concluded all genera present hydrocarbon degraders.
