- The present work was undertaken to assess the extent of crude oil degradation by Bacillus cereus and Pseudomonas aeruginosa isolated from effluents collected from Kaduna Refining and Petrochemical Company, Kaduna, Nigeria. The samples were analyzed microbiologically using standard microbiological techniques. The isolates of Bacillus cereus and Pseudomonas aeruginosa were studied to determine their biodegrading capacities on varying concentrations of crude oil as the sole carbon source using minimal medium. The bacterial growth (increase in cell number cfu/ml) was used as indices of biodegradation. The test on the degrading activity of isolates on crude oil from effluent samples revealed that Bacillus cereus and Pseudomonas aeruginosa were the potent degraders of crude oil. There was statistically significant association between time and the increase in bacterial cell numbers (P = 0.00 < 0.05). The implication of the study in relation to biodegradative activity has been discussed.
