Bioremediation is a cost-effective and environmentally friendly technology that exploits the capabilities of microorganisms to degrade organic pollutants leading to complete mineralization. It has become the most preferred technique for oil spill remediation on soil in Nigeria. This study is aimed at developing a biodegradation model using biodegradation ratios of a biostimulated biodegradation experiment on crude oil polluted/spiked soil. The model design criteria involve inoculating varying Original Research Article
