Halogenation and Dehalogenation Potential of Microorganisms in Yangtze River Waters [PDF]

Microorganisms
The discharge of pollutants into rivers has been increasing with the rapid industrial development and extensive agricultural use of pesticides and herbicides. Halogenated organic compounds (HOCs) represent a significant class of environmental pollutants.

Microbially-mediated halogenation and dehalogenation cycling of organohalides in the ocean [PDF]

Nature Communications
Microbially mediated organohalide cycling in the ocean has profound implications for global biogeochemical cycles and climate, but the geographic distribution and diversity of the halogenation-dehalogenation cycling microorganisms remain unknown.

Evidence of microbial reductive dehalogenation in deep-sea cold seeps and its implications for biogeochemical cycles [PDF]

Microbiome
Background 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

Microbial dehalogenation [PDF]

Current Opinion in Biotechnology, 2001
Novel dehalogenases have been identified recently in various bacteria that utilise halogenated substrates. X-ray studies and sequence analysis have revealed insight into the molecular mechanisms of hydrolytic dehalogenases. Furthermore, genetic and biochemical studies have indicated that reductive dehalogenases are extra-cytoplasmic corrinoid ...

Dehalogenation of Dichlorobenzoates by Acidovorax sp. KKS102’s beta class Glutathione S-transferase and its Mutants

UMYU Journal of Microbiology Research, 2021
Glutathione s-transferases (GSTs) are ubiquitous family of enzymes well known for their detoxification function. Several different classes of the enzyme exist with beta class being the one specific to bacteria.

Potential of Microbial Communities to Perform Dehalogenation Processes in Natural and Anthropogenically Modified Environments—A Metagenomic Study

Microorganisms, 2023
Halogenated organic compounds (HOCs) pose a serious problem for the environment. Many are highly toxic and accumulate both in soil and in organisms. Their biological transformation takes place by dehalogenation, in which the halogen substituents are ...

Dehalogenation reactions between halide salts and phosphate compounds

Frontiers in Chemistry, 2022
Reactions between phosphoric acid [H3PO4] or ammonium hydrogen phosphates [i.e., NH4H2PO4, (NH4)2HPO4] and halide salts can be used to dehalogenate (remove halides from) salt-based waste streams, where the process of removing halides yields products that

Photoredox-Catalyzed Reduction of Halogenated Arenes in Water by Amphiphilic Polymeric Nanoparticles

Molecules, 2021
The use of organic photoredox catalysts provides new ways to perform metal-free reactions controlled by light. While these reactions are usually performed in organic media, the application of these catalysts at ambient temperatures in aqueous media is of
