The contamination of soil and water by used and unused motor oil has continued to pose serious problems in form of economic loss, loss of water lives, ailing soil fertility among several others. Bio remediation is a low-cost alternative green technology that can remediation such polluted soil. This work studies the bio remediation of spent oil-contaminated soil in anaerobic batch reactors at room temperature with cow dung, horse dung, camel dung and donkey dung as organic stimulants over a period of 35 days. The study adopted bio remediation indicators such as oil and grease content, total petroleum hydrocarbon (TPH) and total heterotrophic bacterial counts. Results obtained showed increase in the bacterial population with decrease in crude contents of the polluted soils with time. The treatment options 3 and 4 (addition of cow dung and horse dung) gave the best performance in reduction of oil and grease content by 40 and 60% respectively, and also TPH a treatment H gave the lowest residual percentage of TPH as 0.414%. The study suggested the ability of the organic wastes used to be utilized in enhancing the activities of the microbial hydrocarbon-degrading bacteria during bio remediation of crude petroleum-oil polluted soil.
