Hydrocarbon Biodegradation Potential of Cyanobacteria in Oil Polluted Soil

Petroleum hydrocarbon is one of the most common environmental pollutants in Nigeria and other countries. Its debilitating effects on arable lands and water bodies have far reaching consequences to agriculture and aquatic life. Several bioremediation strategies have been developed over the years in a bid to manage this type of pollution. Cyanobacteria are a group of microorganisms possessing the potential to be harnessed as bioremediation alternatives. This study sought to conduct bioremediation of crude oil polluted oil usung cyanobacteria. Organisms were isolated from crude oil polluted soil and were identified using molecular typing. A 200 ml portion of broth cultures of organisms was used singly and in consortium in different set ups to bio remedaite the polluted soil samples. Gas chromatography was used to monitor the residual total petroleum hydrocarbon TPH in each set up for a period of thirty days. Microcystisholsatica, Chlorella kessleriand Anabaena cicadae were identified from polluted soil samples. Chlorella kessleri gave a 94.10 TPH loss, while Anabaena cicadae gave 91.10 and their co culture set up gave a 95 TPH loss and the control experiment had 2.10 TPH loss. Temperature of the reacting systems was mesophilic and the pH was at weak acid range. This study thus has shown that cyanoremediation of petroleum hydrocarbon pollution of soil is possible and efficient and should be adopted more often Agu, K. C. | Orji, M. U. | Ikele, M.
