Thermochemical Recycling and Degradation Strategies of Halogenated Polymers (F−, Cl−, Br−): A Holistic Review Coupled with Mechanistic Insights

The Chemical Record, Volume 25, Issue 6, June 2025.
This review aims to comprehensively address recent degradation techniques (physical, chemical and biological) of halogenated waste polymers with a prime focus on thermal degradation techniques. Exploiting various metal oxides during co‐pyrolysis is deemed a viable solution for recycling halogenated polymeric waste.

Diverse Reductive Dehalogenases Are Associated with Clostridiales‐Enriched Microcosms Dechlorinating 1,2‐Dichloroethane

BioMed Research International, Volume 2015, Issue 1, 2015., 2015
The achievement of successful biostimulation of active microbiomes for the cleanup of a polluted site is strictly dependent on the knowledge of the key microorganisms equipped with the relevant catabolic genes responsible for the degradation process.

Reductive Dehalogenation Of Chlorinated Benzenes: A Role For Dehalobacter Spp. [PDF]

, 2012
Chlorinated benzenes have been extensively used in industry and agriculture and are common groundwater pollutants. Chlorobenzenes readily migrate to anaerobic zones in sediment and groundwater, thus understanding the fate of these compounds and anaerobic

Insights into the biodegradation process of 2,4,5-trichlorophenoxyacetic acid under anaerobic condition

Ecological Processes
Background Chlorophenoxy compounds represent a group of selective herbicides widely used around the world. Chlorophenoxy herbicides are toxic, chemically stable, and can migrate into groundwater through soil leaching, posing a significant threat to ...

The proton/electron ration of the menaquinone-dependent electron transport from dihydrogen to tetrachloroethene in "Dehalobacter restrictus" [PDF]

Journal of Bacteriology, 1996
In the anaerobic respiration chain of "Dehalobacter restrictus," dihydrogen functioned as the electron donor and tetrachloroethene (PCE) functioned as the electron acceptor. The hydrogenase faced the periplasm, and the PCE reductase faced the cytoplasmic side of the membrane. Both activities were associated with the cytoplasmic membrane.

Biodegradation of chloroethene compounds under microoxic conditions

Biotechnology and Bioengineering, Volume 121, Issue 3, Page 1036-1049, March 2024.
The authors examined the biodegradation of chloroethene compounds under microoxic conditions. The results indicated that partial reductive and cometabolic biodegradation of chloroethene compounds occurred concurrently. The findings of this study have significant implications for further research on chloroethene compound biodegradation, particularly in ...

Refined experimental annotation reveals conserved corrinoid autotrophy in chloroform-respiring Dehalobacter isolates [PDF]

The ISME Journal, 2016
Abstract Two novel chlorinated alkane-respiring Dehalobacter restrictus strains CF and DCA were isolated from the same enrichment culture, ACT-3, and characterized. The closed genomes of these highly similar sister strains were previously assembled from metagenomic sequence data and annotated.

Metabarcoding reveals unique microbial mat communities and evidence of biogeographic influence in low‐oxygen, high‐sulfur sinkholes and springs

Ecology and Evolution, Volume 14, Issue 3, March 2024.
Groundwater‐fed underwater sinkholes and springs create habitats with high‐sulfur, low‐oxygen conditions. Multi‐marker metabarcoding was used to describe microbial mat communities in these extreme aquatic habitats. Unique bacterial and diatom communities were found in five springs in Michigan and Florida, with water parameters and biogeography ...

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
