Abstract

The present study has used soil samples from Nigeria, contaminated with Brass crude-oil, to determine its biodegradation through enhanced biostimulation with cow dung and periodic aeration. Over a period of twenty-eight days, the hydrocarbon-utilizing bacteria (HUB) and hydrocarbon-utilizing fungi (HUF) have been counted and identified. Results from biodegradation of the brass crude-oil over the aforementioned period show that amended crude-oil-spiked soil has had 54. 82% degradation while for amendment and periodic turning this has been 55. 90%, not significantly higher than the former at p≤ 0. 05. Also degradation of spiked soil without cow dung amendment has been 16. 13%. The identified HUB are Staphylococcus aureus, Pseudomonas aeruginosa, Bacillus subtilis, and Streptococcus thermophillus, with individual occurrence of 18. 52% as well as Proteus vulgaris and Micrococcus luteus with 11. 11% and 14. 81% occurrence, respectively. Also, the occurrence rate of HUF like Aspergillus flavus, A. niger, Penicillium chrysogenum, Trichothecium roseum, and Penicillium citrinum have been 15. 63% each; while for Alternaria alternata and Neurospora crazza it has been 6. 25% and for Saccharomyces cerevisae and A. fumigatus, 9. 38% and 3. 13%, respectively. The study concludes that amendment with cow dung and periodic turning of the soil enhance degradation of Brass crude-oil significantly. What is more, aeration by periodic turning slightly improves degradation only with cow dung treatment on Days 21 and 28.
