Dual Element (C/Cl) Isotope Analysis Indicates Distinct Mechanisms of Reductive Dehalogenation of Chlorinated Ethenes and Dichloroethane in Dehalococcoides mccartyi Strain BTF08 With Defined Reductive Dehalogenase Inventories [PDF]
Frontiers in Microbiology, 2020 Dehalococcoides mccartyi strain BTF08 has the unique property to couple complete dechlorination of tetrachloroethene and 1,2-dichloroethane to ethene with growth by using the halogenated compounds as terminal electron acceptor. The genome of strain BTF08

Evidence of microbial reductive dehalogenation in deep-sea cold seeps and its implications for biogeochemical cycles [PDF]
MicrobiomeBackground Reductive dehalogenation is crucial for halogen cycling and environmental remediation, yet its ecological role is not completely understood, especially in deep-sea environments. To address this gap, we investigated the diversity and expression

Original Synthesis of Fluorenyl Alcohol Derivatives by Reductive Dehalogenation Initiated by TDAE [PDF]
Molecules, 2016 We report here a novel and easy-to-handle reductive dehalogenation of 9-bromofluorene in the presence of arylaldehydes and dicarbonyl derivatives to give the corresponding fluorenyl alcohol derivatives and Darzens epoxides as by-products in tetrakis ...

Biochemistry of Catabolic Reductive Dehalogenation [PDF]
Annual Review of Biochemistry, 2017 A wide range of phylogenetically diverse microorganisms couple the reductive dehalogenation of organohalides to energy conservation. Key enzymes of such anaerobic catabolic pathways are corrinoid and Fe–S cluster–containing, membrane-associated reductive dehalogenases.

Cobamide-mediated enzymatic reductive dehalogenation via long-range electron transfer [PDF]
Nature Communications, 2017 Cobalamin-containing reductive dehalogenases from organohalide-respiring bacteria play a key role in the degradation of halogenated organic compounds. Here the authors proposed a catalytic mechanism for dehalogenation that relies on a long-range electron

Reductive Dehalogenation of Bromoform in Aqueous Solution
Environmental Health Perspectives, 1995 The hybrid semiconducter-macrocycle catalyst TiO2-cobalt phthalocyanine promotes the solar photolysis of aqueous bromoform under anaerobic conditions. The major decomposition products are dibromoethane and HBr. Bromomethane and methane were produced only after prolonged photolysis (30 hr).

Understanding the sources, function, and irreplaceable role of cobamides in organohalide-respiring bacteria [PDF]
Frontiers in MicrobiologyHalogenated organic compounds are persistent pollutants that pose a serious threat to human health and the safety of ecosystems. Cobamides are essential cofactors for reductive dehalogenases (RDase) in organohalide-respiring bacteria (OHRB), which ...
