1,2,3,4-Tetrachlorobenzene is a highly recalcitrant pollutant used as a component of dielectric fluids and in organic synthesis. Pseudomonas chlororaphis RW71 mineralizes 1,2,3,4-Tetrachlorobenzene as a sole source of carbon and energy, thereby releasing stoichiometric amounts of chloride (Potrawfke et al., 1998).
The following is a text-format Tetrachlorobenzene pathway map. An organism which can initiate the pathway is given, but other organisms may also carry out later steps. Follow the links for more information on compounds or reactions. This map is also available in graphic (13k) format.
