Today am not coming with much post but little word about bioremediation of oil polluted soil using Agro wastes.
In Nigeria, the oil industry is the most important sector of the economy and it has since experienced tremendous increase as a major economic activity. However, petroleum related activities have been associated with frequent oil spillage especially through oil well blow outs, tanker accidents, pipelines breakage and sabotage leading to recorded incidences of environmental pollution.
This mishaps result in the release of crude oil and refined petroleum products into terrestrial and aquatic environment. Soils which are contaminated by hydrocarbons have extensive damage on local ecosystems since accumulation of pollutants in animals and plants tissue, may cause progeny's death or mutation and ultimately play out on human existence. The global surge in oil pollution due to industrial development, urbanization etc can be tackled through microbial degradation as a route in the natural removal of the oil products from contaminated environments.
Therefore, in this post, two agro wastes that is goat dung and farm compost were investigated and found to be good nutrient supplements for the hydrocarbon utilizing bacteria for bioremediation of soil contaminated with crude oil. It therefore suggests that these agro wastes which are of environmental concern can be beneficial as good nutrient supplements for enhanced bioremediation.
