Isolation and Identification of oil Degrading Bacteria from Izom NNPC Sub-station Niger State

Abstract

This study was carried out to isolate and identify oil degrading bacteria from NNPC sub-station situated at Izom. Oil contaminated soil samples was taken from three (3) different spots in Izom NNPC sub- depot and labeled S1, S2, and S3, while soil sample (control) of same mass was collected from unpolluted soil at the same station. The soil samples were analyzed using standard method. The bacterial species isolated were Pseudomonas aeruginosa, Escherichia coli, Neisseria species, Bacillus subtilis, Micrococcus species, Streptococcus species, and Klebsiella species. From, the data obtained, three isolates namely Pseudomonas species, Bacillus species and Micrococcus species showed excellent degradation activity while other species studied showed moderate and low degradation activity and hence could be exploited in bioremediation activities. The study recommended amongst others that conservationist and environmentalist should adopt the use of bacteria in addressing pollution caused by oil spillage.
