Abstract
The microorganisms associated with soil polluted with petroleum hydrocarbon were isolated at NNPC depot Ibadan, in Ido Local Government Areas of Oyo State. Soil samples were taken from three different points along the point of discharge. The spread plate method was used to isolate the microorganisms found in these rivers and were later identified. From the research, seven different species of microorganism were isolated, which are Pseudomonas sp, Bacillus sp., Micrococcus sp. Staphylococcus aureaus sp., Enterobacter sp., Klebsiella sp. and Escherichia coli. Pseudomonas species were found to be more prominent in the samples collected in a research work. This suggested that the isolates are resistant to the petroleum hydrocarbon and can be recommended as candidates for the clean-up of petroleum hydrocarbon contaminated soil.
