The presence of Polycyclic Aromatic Hydrocarbons (PAHs) in territorial water is of great
concern due to the carcinogenicity. In this study, monthly collection of surface water from
four artisanal petroleum marketing points was made from November 2019 - October 2020 using
standard methods. Hydrocarbon utilizing (Hydrocarbonoclastic) bacteria were isolated by vapour phase
transfer method using mineral salts medium, isolates were identified based on cultural, morphological
and biochemical characteristics. The mean HUB count was 1.2 x 104 cfuml-1. The HUB
isolates were Pseudomonas, 12.4%; Chromobacterium, 1.8%; Serratia, 5.3%;
Corynebacterium, 6.25%; Escherichia, 12.1%; Bacillus, 12.4%; Staphylococcus,
10.6%; Micrococcus, 3.5%; Citrobacter, 7.1%; Enterobacter, 3.5%;
Acinetobacter, 3.5%; Alcaligens, 4.4%; Nocardia, 3.5%; Streptococcus,
6.2%; and Shigella. 6.2%. The PAHs level in the surface water samples were determined
used Gas Chromatography - Flame Ionization Detector, GC-FID. The PAHs level observed was a mean of
0.004mgl-1 which is below the EU permissible limit of 0.007mgl-1; which can be
attributed to activities of the polycyclic aromatic hydrocarbon mineralizing bacteria present as
a natural consortium in the ecosystem. If the presence of these strains of bacteria continues
in the ecosystem, the continual stability of the ecosystem can be ensured. This study reveals
a natural bacterial consortium that can degrade PAH in the surface water within a short time.
