Five genera of crude oil utilizing microorganisms were isolated from oil-contaminated soil. The organisms were identified as Bacillus sp., Pseudomonas aeruginosa, Pseudomonas putida, Aspergillus niger and Mucor plumbus . The isolates were tested for their ability to utilize Bonny Light crude oil using the gravimetric method. The percentage oil utilization for all the isolates ranged between 60.53 and 80.27% after 28 days of incubation. P. putida gave the highest percentage utilization of 80.27% and a rate of utilization of 0.46 mg/ml/day. Increased percentage utilization of 81.58% and rate of utilization of 0.47 mg/ml/day was achieved by a co-culture of P. putida and M. plumbus . The results obtained in this study suggest that P. putida is preferable for treatment of oil spill incidents and that its co-culture with M. plumbus could enhance crude oil utilization.
