Redox chemistry of cobalamin and iron‐sulfur cofactors in the tetrachloroethene reductase of Dehalobacter restrictus [PDF]
Respiration of Dehalobacter restrictus is based on reductive dechlorination of tetrachloroethene. The terminal component of the respiratory chain is the membrane‐bound tetrachloroethene reductase. The metal prosthetic groups of the purified enzyme have been studied by optical and EPR spectroscopy. The 60‐kDa monomer contains one cobalamin with E m(Co1+/

Growth of Dehalobacter and Dehalococcoides spp. during Degradation of Chlorinated Ethanes [PDF]
ABSTRACT Mixed anaerobic microbial subcultures enriched from a multilayered aquifer at a former chlorinated solvent disposal facility in West Louisiana were examined to determine the organism(s) involved in the dechlorination of the toxic compounds 1,2-dichloroethane (1,2-DCA) and 1,1,2-trichloroethane (1,1,2-TCA) to ethene ...

Ecogenomics of microbial communities in bioremediation of chlorinated contaminated sites
Organohalide compounds such as chloroethenes, chloroethanes and polychlorinated benzenes are among the most significant pollutants in the world. These compounds are often found in contamination plumes with other pollutants such as solvents, pesticides ...

Genomic, transcriptomic and proteomic analyses of Dehalobacter UNSWDHB in response to chloroform
Summary Organohalide respiring bacteria (ORB) are capable of utilising organohalides as electron acceptors for the generation of cellular energy and consequently play an important role in the turnover of natural and anthropogenically‐derived organohalides.

Genome Sequence of Dehalobacter sp. Strain TeCB1, Able To Respire Chlorinated Benzenes [PDF]
ABSTRACT Dehalobacter sp. strain TeCB1 was isolated from groundwater contaminated with a mixture of organohalides and is able to respire 1,2,4,5-tetrachlorobenzene and 1,2,4-trichlorobenzene. Here, we report its 3.13-Mb draft genome sequence.

The genus Dehalobacter embraces bacterial populations that seem to exclusively degrade organohalides. All isolates in pure culture and highly enriched strains are obligate organohalide-respiring bacteria that use hydrogen as energy and electron source, acetate as carbon source, and an organohalide as terminal electron acceptor. Depending on the strain,

Reductive dechlorination of β-hexachlorocyclohexane (β-HCH) by a Dehalobacter species in coculture with a Sedimentibacter sp. [PDF]
An anaerobic coculture was enriched from a hexachlorocyclohexane (HCH) polluted soil. The coculture reductively dechlorinates the beta-HCH isomer to benzene and chlorobenzene in a ratio of 0.5-2 depending on the amount of beta-HCH degraded. The culture grows with H(2) as electron donor and beta-HCH as electron acceptor, indicating that dechlorination ...

Effect of Moderate Heat on TCE Reductive Dechlorination Rates in Groundwater
Abstract Low‐temperature heating (in the mesophilic range of ~15 to 40 °C) of contaminated aquifers offers the prospect of increasing the rates for biotic and abiotic treatment of volatile organic compounds. Thermal In Situ Sustainable Remediation (TISR®) is one of the approaches available to implement low temperature heating.
