Bioremediation potentials of chicken droppings on crude oil polluted soil from automobile workshop

The bioremediation properties of chicken droppings on crude oil contaminated soil from automobile workshop in Keffi Nasarawa State of Nigeria were evaluated. Two experimental treatment (T1 and T2) with 10% and 30% chicken dropping addition to the contaminated soil were set up. A control (T3) was also set up consisting of contaminated soil only. The set up design was left for a period of 4 weeks during which the total heterotrophic bacteria (THB) count, total petroleum hydrocarbon degraded and gas chromatography and mass spectroscopy (GCMS) identification of the residue hydrocarbon after remediation were carried out. Soil samples remediated with 30% CD had significantly (p
