Abstract: The quest to harness the vast species of microorganisms inherent in waste dumpsites in Calabar metropolis for bioremediation of hydrocarbon polluted sites formed the focus of this study. Three bacterial species isolated fromLemna dumpsite, Calabar were identified and characterized as Chromobacterium violaceum, Bacillus subtilis and Micrococcus luteus using standard microbiological procedures. The bacterial isolates were then investigated for their hydrocarbon degrading potentials by subjecting them to 5 days fermentation programme in a continuous agitation using three hydrocarbon substrates (Kerosene, diesel and petrol).
