영문 초록

As an emerging remediation technology of petroleum-contaminated soil, composting is the biological conversion of organic-waste materials, under controlled conditions, into a hygienic and relatively biostable product that conditions soil and nourishes plants. Initial research on the composting of petroleum was simply focused on reducing contaminant by optimizing composting conditions. Accordingly, we has required criteria to assess scientifically the biodegradation of hazardous chemicals and data to prove the stability of degradative products. The purpose of this study was to assess the bioremediation feasibility of kerosene-contaminated soil and to provide the data to evaluate systemically composting process by laboratory measurement. A number of heterotrophic, gram-positive, non-spore-forming, and facultative anaerobic bacteria related to kerosene-degrading strains were isolated from composting sampling at various temperature. Isolates were identified as Aeromonas, Corynebacterium, Moraxella, Alcaligenes, and Pseudomonas spp. Under bench-scale composting system, kerosene was mostly removed in 64 days. However, studies with ¹⁴C-labelled hexadecane provided significant evidence that 22.4% of the initial 14C-hexadecane was converted to ¹⁴CO₂ in 64 days.
