A total of sixty-five bacterial and fifteen fungal species were isolated from the soil contaminated by diesel oil around power generators in Obafemi Awolowo and Oduduwa Universities both at Ile-Ife, Osun State. Ten soil samples were taken from each university and microflora from them were identified by appropriate biochemical tests and morphological identification. Seven bacteria and fungi genera each were isolated from both top and deep soil. Bacillus species were the most predominant bacteria from the samples with 57%, Staphylococcus 14%, Neisseria 9%, Micrococcus 9%, Corynebacteria 6%, Klebsiella 3%, Lactobacillus 2% while Aspergillus species were the most predominant of the fungal isolate being 80%, Penicillium 16%, Cunninghamella 1%, Humicola 1%, Beauveria 1%, Gibellula 1%. It is then concluded that organisms that thrive commonly in all samples of soil analysed particularly Aspergillus and Bacillus spp can be developed as seed microflora for bioremediation of oil spilled contaminated soil.
