| Research Abstract |
Hexachlorobenzene (HCB) as a representative material of the persistent organic pollutants was examined microbial dechlorination reaction by a consortium having TCE dechlorination ability. The dechlorination pathway from HCB by this consortium proceeded via trichlorobenzene (TCB), dichlorobenzene (DCB). Genetic analysis of the consortium revealed that Dehalococcoides sp. grew with progress of the dechlorination, the enzyme(s) which were different from the known dechlorination enzyme(s) participated in a reaction.
