This research work is aimed at highlighting the proportional differences in the number of organisms isolated from the various Petroleum product pollution sites. Engine oil and diesel are both petroleum products used in daily activities. These activities may lead to the pollution of the soil due to accidental spills. The pollution sites chosen for the research (two mechanic workshops, a diesel dispensing site and a diesel generator surrounding) were grossly polluted and therefore ideal for the research. From the pollution sites, Pseudomonas spp. Bacillus spp. Micrococcus spp., Staphylococcus spp., Aerococcus spp. were identified after macroscopic, microscopic and biochemical characteristics were analysed. The ability of the organisms to grow on agar containing the pollutants suggested their ability to degrade engine oil and diesel oil by using them as a carbon source. These bacteria therefor have the potential to be used for the breakdown of pollutants in bioremediation. Statistical analysis showed that there was no significant proportion in the number of bacteria present in the different pollution sites (P > 0.05).
