“…Furthermore, vinasse helped the microbial population to overcome the toxicity effects of oil sludge. Although, an increase in the soil microbial population was obtained with vinasse, it was not adequate to enhance the bioremediation efficiency of the oil sludge at the mineralisation level (Crivelaro et al, 2010). However, biostimulation process can enhance the activities and growth of microbial population capable of degrading oil sludge to mineralisation level.…”

“…This involves the management of the natural environment to optimise the growth and activity of the natural microbial population (Crivelaro et al, 2010). The growth and activity of existing microorganisms are accelerated which may be inhibited under normal conditions in water and soil.…”

“…The growth and activity of existing microorganisms are accelerated which may be inhibited under normal conditions in water and soil. According to Crivelaro et al (2010), the low biodegradation efficiency observed in the treatments of oil sludge mixed with soil (landfarming, biopile and composting) are as a result of the imbalanced nutritional amendments. However, biostimulation is one of the possibilities to tackle this kind of problem since oil sludge has limited amounts of nitrogen as well as phosphates.…”

“…However, biostimulation is one of the possibilities to tackle this kind of problem since oil sludge has limited amounts of nitrogen as well as phosphates. This may be because in oil sludge, most of the nitrogen is not available since it is part of complex structures relatively inaccessible to the degrading microbial population (Crivelaro et al, 2010). In their study, Crivelaro et al (2010), evaluated the potentials of biostimulation process using vinasse a byproduct from processed sugarcane which contains adequate nutrients such as nitrogen, phosphorus and potassium (Cortez and Brossard Perez, 1997;Carmen Baez-Smith, 2006), as the microbial stimulating nutrient agent for biodegradation of oil sludge.…”

Oil sludge is a thick viscous mixture of sediments, water, oil and hydrocarbons, encountered during crude oil refining, cleaning of oil storage vessels and waste treatment. Polycyclic aromatic hydrocarbons (PAHs), which are components of crude oil sludge, constitute serious environmental concerns, as many of them are cytotoxic, mutagenic and potentially carcinogenic. Improper management and disposal of oil sludge causes environmental pollution. The adverse effects of oil sludge on soil ecology and fertility have been of growing interest among environmental scientist and an important consideration in the development of efficient technologies for remediation of contaminated land, with a view to making such land available for further use. Oil sludge can be treated by several methods such as physical, chemical and biological processes. The biological processes are mostly cost effective and environmentally friendly, as they are easy to design and implement, as such they are more acceptable to the public. Compost, the product of biological breakdown of organic matter is a rich source of hydrocarbon-degrading microorganisms such as bacteria and fungi. These microorganisms can degrade the oil sludge to less toxic compounds such as carbon dioxide, water and salts. Compost bioremediation, the application of composting in remediation of contaminated environment, is beginning to gain popularity among remediation scientists. The success or failure of compost bioremediation depends on a number of factors such as nutrients, pH, moisture, aeration and temperature within the compost pile. The bioavailability and biodegradability of the substrate to the degrading microorganisms also contributes to the success of the bioremediation process. This is a review on the biological remediation technologies employed in the treatment oil sludge. It further assesses the feasibility of using compost technology for the treatment of oil sludge, as a better, faster and more cost effective option.

Aims: This present study aim at assessing the efficacy of soil-organic nutrient stimulant in the remediation of oily waste. Study design: Preparation of Soil-goat dung mix was used as stimulant for the remediation of oily waste. Place and duration of study: The study was carried out at the Department of Microbiology University of Uyo, Uyo, Akwa Ibom state, Nigeria in the dry season months of January - March Methodology: Remediation of oily waste using soil - organic (goat dung) nutrient stimulant was assessed for 12 weeks using standard culture-dependent microbiological, chemical and enzyme activity assay procedures. Results: The results indicate increased counts of hydrocarbon utilizing bacteria, fungi and actinomycetes with remediation time. Microorganisms belonging to the genera Bacillus, Pseudomonas, Acinetobacter, Alcaligenes, Serratia, Penicillium, Aspergillus, Cladosporium, Rhodococcus, Nocardia and Streptomyces were recovered from the remediated waste. The pH of the soil-goat dung treatment ranged from 6.5 ± 0.02 to 7.1 ± 0.05. Enzyme activity by dehydrogenase and urease were higher than phenol oxidase with time. PAHs were below detectable limits (< 0.01) and reduction in total petroleum hydrocarbon was 99.3% for the remediated waste. Conclusion: Overall, enhanced microbial activities correlated positively with reduction in Total Petroleum Hydrocarbon and PAH composition which resulted in ecofriendly waste product. Soil-goat dung stimulant can therefore serve as a cheap alternative in the management of oily waste.
