Identification of Dehalobacter reductive dehalogenases that catalyse dechlorination of chloroform, 1,1,1-trichloroethane and 1,1-dichloroethane [PDF]

Philosophical Transactions of the Royal Society B: Biological Sciences, 2013
Two novel reductive dehalogenases (RDases) that are highly similar to each other but catalyse distinct dechlorination reactions were identified from Dehalobacter -containing mixed cultures. These two RDases were partially purified from crude protein extracts of anaerobic dechlorinating enrichment cultures using blue

Isolation and characterization of Alicycliphilus denitrificans strain BC, which grows on benzene with chlorate as the electron acceptor [PDF]

, 2008
A bacterium, strain BC, was isolated from a benzene-degrading chlorate-reducing enrichment culture. Strain BC degrades benzene in conjunction with chlorate reduction.

Modeling reveals metabolic basis of competition among Dehalobacter strains during tandem CF and DCM metabolism

bioRxiv
SC05-UT is an anaerobic mixed microbial enrichment culture that reduces chloroform (CF) to dichloromethane (DCM) through reductive dechlorination, which it further mineralizes to carbon dioxide.

The Membrane-Bound C Subunit of Reductive Dehalogenases: Topology Analysis and Reconstitution of the FMN-Binding Domain of PceC

Frontiers in Microbiology, 2018
Organohalide respiration (OHR) is the energy metabolism of anaerobic bacteria able to use halogenated organic compounds as terminal electron acceptors.

Molecular basis of cobalamin-dependent RNA modification [PDF]

, 2016
Queuosine (Q) was discovered in the wobble position of a transfer RNA (tRNA) 47 years ago, yet the final biosynthetic enzyme responsible for Q-maturation, epoxyqueuosine (oQ) reductase (QueG), was only recently identified.

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. 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+/

Functional Genes and Bacterial Communities During Organohalide Respiration of Chloroethenes in Microcosms of Multi-Contaminated Groundwater

Frontiers in Microbiology, 2019
Microcosm experiments with CE-contaminated groundwater from a former industrial site were set-up to evaluate the relationships between biological CE dissipation, dehalogenase genes abundance and bacterial genera diversity.

Impact of Anaerobic Cold Storage on Subseafloor Microbial Communities

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 12, December 2025.
Abstract Sediment cores recovered from the deep sea often cannot be sampled for microbiological analysis immediately due to the need for core splitting and processing for subsequent onboard measurements and core storage. Consequently, sections are often stored at 4°C under anaerobic conditions for extended periods.

Reductive dechlorination in the energy metabolism of anaerobic bacteria [PDF]

, 2017
Within the last few decades, several anaerobic bacteria have been isolated which are able to reductively dechlorinate chlorinated aliphatic and aromatic compounds at catabolic rates.

Assimilative and co-metabolic degradation of chloral hydrate by bacteria and their bioremediation potential [PDF]

, 2011
Although the bacterial degradation of chloral hydrate (CH) has been recognized for several decades, its degradation pathway by assimilation has not been demonstrated.
