Abstract

The mineralization of diesel-based engine oils produced by African Petroleum (AP) was investigated for a period of twenty-eight (28) days. Two different samples of AP engine oils, Heavy Duty Visco SAE40 (H40) and Diesel Motor Oil SAE 40 (D40) were investigated. Soil from a mechanic workshop at Irediawa Junction, along Ekenwan Road, Benin City, Edo State, Nigeria served as seed for the mineralization. The study was carried out at room temperature (27-290C). The pH of the test systems ranged from 6.6 to 4.8 where the count in first day were 2.56x102 and 4.46 x105, for H40 and D40 respectively whereas the corresponding count on day 28 were 2.32 x104 and 3.85 x104 in colony forming unit per milliliters (cfu/ml). The hydrocarbon utilizing fungal isolates were identified as Aspergillus, Fusarium, Mucor, Penicillium Rhizopus, and Saccharomyces. The physicochemical analysis showed that nitrate, phosphate, sulphate, biochemical oxygen demand, (BOD), oil and grease content and total organic carbon (TOC) decreased with time. The rate mineralization between the two engine oils was in accordance with the normal growth rate for a close system. There was no significant difference between the rates of mineralization of the two engine oils.
