This study aimed to effectively decontaminate fuel oil-contaminated soil using ex-situ bioremediation. Soil samples (contaminated with waste oils) from Serbia were treated. The results showed several significant changes after bioremediation. The pH levels became slightly more alkaline (7.0–7.5). Reduction in organic substance (34%) and carbonate (36%) were observed, respectively. The concentration of n-hexane extractable substances and total petroleum hydrocarbons decreased by around 90%, including a significant reduction in hydrocarbons containing 17 C and 18 C atoms. Total carbon, organic carbon, and total hydrogen content also decreased notably. The presence of a high number of microorganisms indicated active aerobic and anaerobic processes in the soil. Overall, the results confirmed a high degree of feasibility of the applied conditions for bioremediation of soil contaminated with waste oils. HIGHLIGHTS: After bioremediation: the loss of organic substances was about 34%; the loss of carbonate was about 36%; the value of n-hexane extractable substance decreased by ∼90%; the total petroleum hydrocarbons content decreased by ∼90%; the content of hydrocarbons pristane and phytane was drastically reduced; the soil contaminated with fuel oil was successfully cleaned.
