CENSUS – Chlorinated Benzenes
Detect and quantify bacteria responsible for biodegradation of Chlorinated Benzenes
Chlorinated benzenes are an important class of industrial solvents and chemical intermediates in the productions of drugs, dyes, herbicides and insecticides. The physical-chemical properties of chlorinated benzenes as well as susceptibility to biodegradation are functions of their degree of chlorination and the positions of chlorine substituents.
In general, chlorobenzenes with four or less chlorine groups are susceptible to aerobic biodegradation even serving as growth supporting substrates.
Under anaerobic conditions, reductive dechlorination of higher chlorinated benzenes including hexachlorobenzene (HCB), pentachlorobenzene (PeCB), tetrachlorobenzene (TeCB) isomers, and trichlorobenzene (TCB) isomers by halorespiring bacteria has been well documented (Field and Sierra-Alvarez 2008).
CENSUS Targets for Reductive Dechlorination
The following table describes the individual CENSUS targets, their importance in evaluating reductive dechlorination as a treatment mechanism.
