Comparison of biostimulation and bioaugmentation techniques for the remediation of used motor oil contaminated soil

Abstract

This study was carried out on the bioremediation of used motor oil contaminated soil artificially contaminated to a pollutant level of 40,000ppm using biostimulation and bioaugmentation remediation techniques for 42 days. Four treatment options were investigated in wooden microcosms: Control (T1), water amended (T2), biostimulation (T3) and hybrid of biostimulation and bioaugmentation (T4). The effectiveness of bioremediation processes were monitored using the total petroleum hydrocarbon removal (TPH) and total bacterial count (TBC

Comparison of biostimulation and bioaugmentation for remediation of soil contaminated with spent motor oil

“…Most work reported in the literature on the biological treatment of soil contaminated with used motor oil had been focused on the identification of microorganisms, which can be used to degrade used motor oil (Amund et al, 1987) and the use of plants for the degradation of used motor oil (Anoliefo and Edegbai, 2000). Besides, other works prior to this investigation were based on biological treatments of soil contaminated with spent motor oil in open microcosms (Bagherzadeh-Namazi et al, 2008;Abdulsalam and Omale, 2009). The objectives of this study were to examine the effectiveness of bioremediation of spent motor oil contaminated soil in a closed system and to compare the hydrocarbon removal efficiencies of spent motor oil contaminated soil between the bioaugmentation and biostimulation approaches in order to develop a viable treatment technology.…”

Factors influencing crude oil biodegradation by Yarrowia lipolytica

“…Bioremediation is an internationally approved technology for the costeffective clean-up of oil-contaminated sites. These technologies involve enhancing the natural biological transformation of chemical-or petroleum-derived contaminants into less toxic and/or less mobile forms (Abdulsalam and Omale 2009). These technologies are receiving increased attention due to their low cost and effectiveness (Vidali 2001).…”

Bioremediation of Soil Contaminated With Used Motor Oil in a Closed System

“…Most work reported in the literature on the biological treatment of soil contaminated with used motor oil had been focused on the identification of microorganisms, which can be used to degrade used motor oil [7], and the use of plants for the degradation of used motor oil [8]. In addition, other works prior to this investigation were based on biological treatments of soil contaminated with spent motor oil in open systems [9,10].…”
