목재재질의 담체를 혼합한 토양에서 Bacillus subtilis에 의한 PAH분해에 대한 연구
A Study of PAH (polyaromatic hydrocarbon) Biodegradation in Soil by Bacillus subtilis mixed with Wooden Media

PAHs는 2개 이상의 벤젠링을 가지는 방향족 탄화수소로, 특성과 분자량에 의해 크게 두 가지로 구분되며, 독성 유기물질들이 직
PAHs are aromatic hydrocarbon compunds with two or more benzene rings. Because they are mostly toxic to human life, they need to be converted to non-toxic compunds or to be degraded completely. This work aims to degrade PAHs (phenanthrene and pyrene) using Bacillus bacteria covered on cork or sawdust. The results show that media effect on phenanthrene was negligible whereas biodegradation ability of sawdust carrying the bacteria was better than that of biofilm-covered cork when pyrene was tested. PAH removal was also affected by soil moisture content with
