mBio, 2018 Organohalide compounds are widespread in the environment as a result of both anthropogenic activities and natural production. The marine environment, in particular, is a major reservoir of organohalides, and reductive dehalogenation is thought to be an ...

The Complexome of Dehalococcoides mccartyi Reveals Its Organohalide Respiration-Complex Is Modular
Frontiers in Microbiology, 2018 Dehalococcoides mccartyi strain CBDB1 is a slow growing strictly anaerobic microorganism dependent on halogenated compounds as terminal electron acceptor for anaerobic respiration.

Acetylene Fuels TCE Reductive Dechlorination by Defined Dehalococcoides/Pelobacter Consortia. [PDF]
, 2017 Acetylene (C2H2) can be generated in contaminated groundwater sites as a consequence of chemical degradation of trichloroethene (TCE) by in situ minerals, and C2H2 is known to inhibit bacterial dechlorination. In this study, we show that while high C2H2 (

Initial Characterization of a Reductive Dehalogenase from Desulfitobacterium chlororespirans Co23 [PDF]
Applied and Environmental Microbiology, 1996 Desulfitobacterium chlororespirans Co23 is capable of using 3-chloro-4-hydroxybenzoate as terminal electron acceptor for growth. Membrane preparations from cells grown fermentatively on pyruvate in the presence of 3-chloro-4-hydroxybenzoate dechlorinated this compound at a rate of 3.9 nmol min(sup-1) mg of protein(sup-1).

Multiple Dual C−Cl Isotope Patterns Associated with Reductive Dechlorination of Tetrachloroethene [PDF]
, 2017 Dual isotope slopes are increasingly used to identify transformation pathways of contaminants. We investigated if reductive dechlorination of tetrachloroethene (PCE) by consortia containing bacteria with different reductive dehalogenases (rdhA) genes can

Identification of a reductive tetrachloroethene dehalogenase in Shewanella sediminis [PDF]
Philosophical Transactions of the Royal Society B: Biological Sciences, 2013 The genome sequence of psychrophilic Shewanella sediminis revealed the presence of five putative reductive dehalogenases (Rdhs). We found that cell extracts of pyruvate/fumarate-grown S. sediminis cells catalysed reduced methyl viologen-dependent reductive dechlorination of tetrachloroethene (

Scientific Reports, 2017 We have developed and characterized a bacterial consortium that reductively dechlorinates trichloroethene to ethene. Quantitative PCR analysis for the 16S rRNA and reductive dehalogenase genes showed that the consortium is highly enriched with ...

Purinyl-cobamide is a native prosthetic group of reductive dehalogenases [PDF]
Nature Chemical Biology, 2017 Cobamides such as vitamin B12 are structurally conserved, cobalt-containing tetrapyrrole biomolecules that have essential biochemical functions in all domains of life. In organohalide respiration, a vital biological process for the global cycling of natural and anthropogenic organohalogens, cobamides are the requisite prosthetic groups for carbon ...

Coexistence of two distinct Sulfurospirillum populations respiring tetrachloroethene - genomic and kinetic considerations [PDF]
, 2018 Two anaerobic bacterial consortia, each harboring a distinct Sulfurospirillum population, were derived from a 10 year old consortium, SL2, previously characterized for the stepwise dechlorination of tetrachloroethene (PCE) to cis-dichloroethene (cis-DCE)
