Catalytic Reductive Dehalogenation of Hexachloroethane by Molecular Variants of Cytochrome P450cam (CYP101)

FEBS Journal, 2000
CYP101 (cytochrome P450cam) catalyses the oxidation of camphor but has also been shown to catalyse the reductive dehalogenation of hexachloroethane and pentachloroethane.

Identification of Microorganisms Involved in Reductive Dehalogenation of Chlorinated Ethenes in an Anaerobic Microbial Community

Water Research, 2005
In this study, we report on phylogenetic and physiological characterization of an anaerobic culture capable of reductive dehalogenation of tetrachloroethene (PCE) obtained from a PCE-contaminated site.

Reductive Dehalogenation – Challenges of Perfluorinated Organics

Journal of Photocatalysis, 2021
: In this mini-review, the problem of effective elimination of perfluorinated organic micropollutants from aquatic environment has been touched. The extraordinary chemical stability of common perfluorinated organic surfactants results in unsatisfactory efficiency of conventional treatment processes, which opens perspectives for photocatalytic methods -

Electrochemical reductive dehalogenation of chlorobenzenes

Russian Chemical Bulletin, 1995
Electrochemical dechlorination of 1,2,3,5-tetrachlorobenzene in methanol and chlorobenzene in dimethylsulfoxide with tetraalkylammonium salts as supporting electrolytes was carried out. The extent of dechlorination depends significantly on the electrode composition.

Reductive dehalogenation of chlorinated dioxins by an anaerobic bacterium

Nature, 2003
Polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDDs and PCDFs) are among the most notorious environmental pollutants. Some congeners, particularly those with lateral chlorine substitutions at positions 2, 3, 7 and 8, are extremely toxic and carcinogenic to humans.

Humin as an Electron Mediator for Microbial Reductive Dehalogenation

Environmental Science & Technology, 2012
We report that humins extracted as the solid fractions from paddy soils or sediment are involved in extracellular electron transfer, coupled with microbial reductive dehalogenation of pentachlorophenol (PCP), by serving as both electron acceptor and electron donor.

Reductive Dehalogenation of Dichlorobenzenes and Monochlorobenzene to Benzene in Microcosms

Environmental Science & Technology, 2009
Anaerobic microcosms were constructed using sediments from a historically chlorobenzene-contaminated site and were provided with yeast extract as an electron donor. In these methanogenic microcosms, all three isomers of dichlorobenzene (DCB) were reductively dehalogenated to monochlorobenzene (MCB) when added together or individually, with 1,2-DCB ...

Trichloroacetic acid dehalogenation by reductive radicals

Inorganica Chimica Acta, 2007
Abstract Advanced oxidation processes, using either UVC/H2O2 or UVC/K2S2O8, both in the presence of H2CO2 or CH3OH are very efficient in mineralizing aqueous solutions of trichloroacetic acid (TCAA) leaving no toxic residues. The main reaction initiating TCAA depletion is its reduction by the radicals CO 2 - or CH2OH to ...
