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.

Frequent concomitant presence of Desulfitobacterium spp. and " Dehalococcoides ” spp. in chloroethene-dechlorinating microbial communities [PDF]

, 2018
The presence of chloroethene dechlorination activity as well as several bacterial genera containing mainly organohalide-respiring members was investigated in 34 environmental samples from 18 different sites.

Interaction of Polybrominated Diphenyl Ethers and Aerobic Granular Sludge: Biosorption and Microbial Degradation

BioMed Research International, Volume 2014, Issue 1, 2014., 2014
As a new category of persistent organic pollutants, polybrominated diphenyl ethers (PBDEs) have become ubiquitous global environmental contaminants. No literature is available on the aerobic biotransformation of decabromodiphenyl ether (BDE‐209). Herein, we investigated the interaction of PBDEs with aerobic granular sludge.

Reductive dechlorination of β-hexachlorocyclohexane (β-HCH) by a Dehalobacter species in coculture with a Sedimentibacter sp. [PDF]

FEMS Microbiology Ecology, 2005
An anaerobic coculture was enriched from a hexachlorocyclohexane (HCH) polluted soil. The coculture reductively dechlorinates the beta-HCH isomer to benzene and chlorobenzene in a ratio of 0.5-2 depending on the amount of beta-HCH degraded. The culture grows with H(2) as electron donor and beta-HCH as electron acceptor, indicating that dechlorination ...

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 ...

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 ...

Heterologous expression, purification and cofactor reconstitution of the reductive dehalogenase PceA from Dehalobacter restrictus

Protein Expression and Purification, 2012
Organohalide respiration is used by a limited set of anaerobic bacteria to derive energy from the reduction of halogenated organic compounds. The enzymes that catalyze the reductive dehalogenation reaction, the reductive dehalogenases, represent a novel and distinct class of cobalamin and Fe-S cluster dependent enzymes.

Experimental determination of isotope enrichment factors – bias from mass removal by repetitive sampling [PDF]

, 2016
Application of compound-specific stable isotope approaches often involves comparisons of isotope enrichment factors (ε). Experimental determination of ε-values is based on the Rayleigh equation, which relates the change in measured isotope ratios to the ...

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 ...
