Bacterial biodegradation of petroleum hydrocarbon using local isolates from tropical polluted environmental media


George Ubong, Inyang-Etoh Aniema, Ekpo Antai

Studies on bacterial biodegradation of petroleum hydrocarbon using local isolates from tropical polluted environmental media (soil and water) in Ibeno Local Government Area, Akwa Ibom State was conducted between October to December, 2016 with the aim of isolating bacteria strain that has the ability to biodegrade petroleum hydrocarbon in the event of pollution. In the laboratory standard procedures for isolating and identification of bacteria strains was adhere to. The bacteria were identified as species of Baciillus (60%), Micrcoccus (30%) and Alcaligenes (10%). The aliphatic hydrocarbon was more readily utilized than the aromatics. Further studies revealed that Bacillus megaterium CDB5 and Micrococcus luteus CDB2 degraded the both type of diesel oil effectively. However, B. megaterium showed considerably higher ability in degrading both light and thick diesel oil than M. luteus. B. megaterium was able to cause weight losses of 49.5% and 41.9% of transniger pipeline and bonny light diesel oil respectively after 10 days of incubation while M. luteus cause weight losses of 35.5% and 29.1% of transniger pipeline and bonny light diesel oil respectively over the same incubation period and environmental conditions. B. megaterium also emulsify the both types of diesel oil while M. luteus could not emulsify any of the diesel oil used for the study. Based on the findings from the result of this study B. megaterium CDB5 could serve as a potential candidate in seedling of oil spill environment in the event of pollution.
