The Bioremediation of Petroleum Sludge (PS) in a clay soil environment of the Niger Delta region of Nigeria using Moringa Seed oil extract (MO) as a Biostimulator (BS) has been investigated, with a view to studying the mitigation impact on the total petroleum hydrocarbon (TPH) content of the petroleum sludge. Two Bioreactors labeled R1 (with MO treatment) and R2 (control: No treatment) containing 3.0kg of clay soils were polluted with 300ml of petroleum sludge. 50ml of MO was added to R1 as a biostimulator. R2 received no form of treatment. Bioremediation extent monitoring was carried out bi-weekly by sampling of the bioreactors contents and analyzing for the individual petroleum hydrocarbon using a gas chromatography (GC). Analysis of the samples at two weeks intervals for a period of 12 weeks reveals that bioremediation occurred in the treatment reactor and the control reactor to which no biostimulator was added. Most of the Hydrocarbon degradation occurred within the first four weeks of the experiment. It was found that moringa seed oil extract was very effective and suitable for remediation of petroleum sludge polluted clay soils due to the high degradation rates of the individual hydrocarbons recorded in the biostimulated reactor against the low degradation rates of those of the control reactor with no form of bio-treatment.
