ABSTRACT

Bioremediation is an important technology for the restoration of oil polluted environments by indigenous or selected microorganisms. In general, the rate of biodegradation depends on the number and types of micro-organism, the nature and chemical structure of pollutants to be degraded and the environmental conditions. In this study, the efficacy of the biodegradation potentials of foreign (  PETROX HC 500, PETROX HC 600, PETROX HC 100, PETROX HC 1150 AND PETROX HC 339 ) and local materials(Saw dust and Poultry dropping) was compared by application of different biostimulation treatments for the biodegradation of the crude oil contaminated soils. Microbial activity was evaluated following growth of heterotrophic and degrading microorganisms. Hydrocarbons degradation was established by determination of TPH using a clarity GC/MS. During this period, total petroleum hydrocarbons and changes in bacterial communities was monitored. The foreign stimulant recorded a TPH reduction of 40.2% while the local stimulant only recorded a TPH reduction of 7.7%. In the  soil, the dominant microorganism population comprises Bacillus Spp and S.Epididymis and they are all Gram-positive bacteria.  These results have shown that the combination of the foreign materials (PETROX HC 500, PETROX HC 600, PETROX HC 100, PETROX HC 1150 AND PETROX HC 339) is an efficient treatment to be applied in remediation of crude oil contaminated soil.
