Redox Chemistry of Cobalamin and Iron-Sulfur Cofactors in the Tetrachloroethene Reductase of Dehalobacter Restrictus [PDF]

FEBS Letters, 1997
Respiration of Dehalobacter restrictus is based on reductive dechlorination of tetrachloroethene. The terminal component of the respiratory chain is the membrane-bound tetrachloroethene reductase.

Isolation and Characterization of Dehalobacter sp. Strain UNSWDHB Capable of Chloroform and Chlorinated Ethane Respiration

Environmental Microbiology, 2016
Dehalobacter sp. strain UNSWDHB can dechlorinate up to 4 mM trichloromethane at a rate of 0.1 mM per day to dichloromethane and 1,1,2-trichloroethane (1 mM, 0.1 mM per day) with the unprecedented product profile of 1,2-dichloroethane and vinyl chloride ...

The Restricted Metabolism of the Obligate Organohalide Respiring Bacterium Dehalobacter Restrictus: Lessons From Tiered Functional Genomics

Philosophical Transactions of the Royal Society B: Biological Sciences, 2013
Dehalobacter restrictus strain PER-K23 is an obligate organohalide respiring bacterium, which displays extremely narrow metabolic capabilities. It grows only via coupling energy conservation to anaerobic respiration of tetra- and trichloroethene with ...

Metagenome Analysis Reveals yet Unexplored Reductive Dechlorinating Potential of Dehalobacter sp. E1 Growing in Co-Culture With Sedimentibacter sp.

Environmental Microbiology Reports, 2012
The importance of Dehalobacter species in bioremediation as dedicated degraders of chlorinated organics has been well recognized. However, still little is known about Dehalobacter's full genomic repertoires, including the genes involved in dehalogenation.

Microbial Reductive Dehalogenation of Trihalomethanes by a Dehalobacter-Containing Co-Culture

Applied Microbiology and Biotechnology, 2017
Trihalomethanes such as chloroform and bromoform, although well-known as a prominent class of disinfection by-products, are ubiquitously distributed in the environment due to widespread industrial usage in the past decades. Chloroform and bromoform are particularly concerning, of high concentrations detected and with long half-lives up to several ...

A multifunctional Dehalobacter ? Tandem chloroform and dichloromethane degradation in a mixed microbial culture

Environmental Science & Technology, 2023
ABSTRACT Chloroform (CF) and dichloromethane (DCM) contaminate groundwater sites around the world, which can be remediated through bioaugmentation. Although several strains of Dehalobacter restrictus can reduce CF to DCM, and multiple Peptococcaceae can ferment DCM, these processes ...

Chloroform respiration to dichloromethane by a Dehalobacter population

Environmental Microbiology, 2010
Summary Chloroform (CF), or trichloromethane, is an ubiquitous environmental pollutant because of its widespread industrial use, historically poor disposal and recalcitrance to biodegradation. Chloroform is a potent inhibitor of metabolism and no known organism uses it as a growth substrate.

Involvement of Dehalobacter strains in the anaerobic dechlorination of 2,4,6-trichlorophenol

Journal of Bioscience and Bioengineering, 2013
A culture reductively dechlorinating 2,4,6-trichlorophenol (TCP) was enriched from a sediment contaminated with chlorinated aliphatic hydrocarbons. The culture dechlorinated 100 μM of 2,4,6-TCP to 4-chlorophenol within 15 days utilizing H2 and a yeast extract as an electron donor and carbon source, respectively.
