  Different microbes (E.coli, Proteus, Klebsiella and Pseudomonas sp) were utilized in degradation of different hydrocarbon (Engine oil/diesel, kerosene and fuel) contaminated soils amended with inorganic (NPK and urea) and organic (cow dung and poultry litter) fertilizers and in some their combination. The incubation period ranged from 3 – 18 days. Bacterial population count and residual hydrocarbon were determined .Results showed that bacterial population count increased as the microbes utilized hydrocarbon for carbon and energy sources, the increase in population count and degradation of the hydrocarbons was stimulated by the fertilizer. It was also observed that as the population count increased due to hydrocarbon utilization for carbon and energy, residual hydrocarbon decreased and percentage degradation increased. Urea fertilizer was the best amendment for E.coli to degrade .. View More»
