dc.description.abstractSoil samples collected from engine oil dump sites, diesel polluted sites and uncontaminated plots (controls) were analyzed for oil-degrading and heterotrophic bacteria following standard microbiological and biochemical methods. The pH readings of the different bacterial isolates grown in Mineral Salt Media (MSM) for 16 days, Optical density readings, enumeration of bacterial isolates in the different MSM were used as indices for comparison of the rate of biodegradation of the diesel types.Nine indigenous microorganisms were isolated from both the engine oil and petrodiesel contaminated soils using the enrichment technique. Oil degraders isolated include: Pseudomonas aeruginosa, Pseudomonas cepacia, Staphylococcus schleiferi, Pseudomonas fluorescens, Bacillus subtilis, Klebsiellapneumoniae, Staphylococcus chromogenes, Escherichia coli and Micrococcus varians.Heterotrophic bacterial counts were significantly higher (P < 0.05) in non-impacted than in impacted soils. Conversely, the population of oil degraders was significantly lower in non-impacted than in impacted soils. The pH range was 3.90-5.70 while the absorbance at 600nm range was 0.10 -1.17. The bacterial plate counts in MSM supplemented with biodiesel were higher than in those supplemented with biodiesel blend and petrodiesel. Results show that biodiesel is more easily and faster biodegraded than petrodiesel. This finding could be exploited in case of oil-spill clean-up campaigns.en_US
