Dechlorinating Bacteria in BCI Cultures. To address single compounds or a mixture of chlorinated ethenes, BCI cultures contain at least two types of Dehalococcoides (Dhc) (based on genetic evidence for two types of VC-reductase). Specialized BCI cultures also include Dhc which tolerate the presence of 1,1,1-TCA, which inhibits most native Dhc. For sites contaminated with 1,1,1-TCA and 1,1-DCA, BCI provides cultures containing Dehalobacter species. BCI also maintains Dhc cultures which dechlorinate 1,2-dichloroethane, 1,2-dichloropropane, and highly chlorinated chlorobenzenes. The newest culture can dechlorinate CF in the presence of other chlorinated compounds.
Bioremediation Consulting Inc (BCI) develops an anaerobic chloroform-degrading culture
BCI’s newest culture is a microbial mixture (consortia) which can transform chloroform (CF) to dichloroemthane (DCM), a transient intermediate which is then converted to a non-chlorinated product. We have demonstrated that the culture can dechlorinate at least 10 ppm of chloroform.
