Bactrerium inhabiting in Amarume crude oil of Yamagata prefecture was identified as Pseudomonas mendocina. In the first step, biodegradation experiments were conducted by using the bacteria of 0.5106 cells / ml and 300 ppm of chlorobenzene in aqueous solution under aeration and irradiation. After 6 hours, chlorobenzene was perfectly decomposed. Next, the mixtures of synthesized polychlorinated dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs) were degraded with the bacteria of 0.5108 cells / ml, where the initial total concentrations of PCDDs and PCDFs were 1,400 ppm and 180 μg-TEQ / ml. After 24 hours, about 70 % of PCDDs and 60 % of PCDFs were biodegraded. The biodegradation rates of PCDD / Fs were much faster than those reported in literatures with other bacteria.
