BIOREMEDIATION OF SOIL CONTAINING DIOXINS BY USING BACTERIA IN CRUDE OIL

Fujita Toyohisa, Dodbiba Gjergj, Shibayama Atsushi, Vo Dinh Long

Tóm tắt


The mixed bacteria collected from the water phase in crude oil deposit shows the decomposition of dioxin by adding the soil, mixing and settling. High concentration 50 ppm of dioxin in soil could decompose without nutritional salts at the rate of 60% after 6 weeks. Low concentration 10 ppm of dioxin in soil could decompose with nutritional salts at the rate of 80% after 6 weeks. If the dioxins still remain in the soil in Vietnam, there would be a possibility to decompose by using these bacteria inhabiting water separated from crude oil.

Keywords: Bioremediation, soil, dioxin, decomposition, water phase in crude oil.
