Development of Three Bacteria Consortium for the Bioremediation of Crude Petroleum-oil in Contaminated Water

We have to developed active microbial consortium that could be of higher degradation of crude oil contaminated groundwater, wastewater aeration pond and biopond at the oil refinery Terengganu Malaysia. Among four isolates that showed good growth only three different isolates (Acinetobacter faecalis WD2, Staphylococcus. sp DD3 and Neisseria elongate TDA4.) were selected based on the growth ability and degradation. Significant growth and effectiveness of hydrocarbon biodegradation of the bacterial consortium examined bacterial strains and their mixtures in both were observed after 5, 10 and 15 days of degradation. Gas chromatography showed that more than 96 and 98% degradation of total hydrocarbon by consortia sp respectively.
