유류 오염지역으로부터 분리된 균주를 이용한 항공유의 분해

초록

Bioremediation has been showing promise as an alternative to conventional environmental cleanup technologies. The objective of this study is to maximize the degradability of jet fuel in the soil system. The cells isolated from petroleum contaminated site was used for the degradation of jet fuel. When this strain was cultured in the MSM(minimal salt media) containing jet fuel for ten days, the degradability of jet fuel was almost 100%. The concentration of jet fuel did not affect the degradability much and the increased inoculation of strain and addition of nitrogen source decreased the time for complete degradation of jet fuel in the liquid culture. Inoculation of this strain increased the jet fuel degradability in the soil column by 15% and the aeration(50ml/min) and the addition of nutrient(NaNO3, KH2PO4) enhanced the jet fuel degradability(about 90%).
