Abstract
This study focused on the processing time reduction of soils microcosm process, during the biological restore of diesel-contaminated soil under natural conditions. Biodegradation activity of hydrocabonoclastic microflora and biostimulation with inorganic nutrient (NPK) were studied through the determination of optimal conditions which improve bioremediation process. Indeed, after 56 days, about 98% removal rate of total petroleum hydrocarbon (TPH) in soil treated by microcosm’s technique were observed relative to approximately 2.22×107CFU/g soil of bacterial number. This performance was achieved with microbial (bacteria) metabolism which accompanies biodegradation of hydrocarbons. Moreover, the hydrocarbon fractions (alkanes and aromatics) were rapidly degraded then the other complex fractions according to GC/MS and FT-IR analysis
