Microbial Community Response of an Organohalide Respiring Enrichment Culture to Permanganate Oxidation. [PDF]

PLoS ONE, 2015
While in situ chemical oxidation is often used to remediate tetrachloroethene (PCE) contaminated locations, very little is known about its influence on microbial composition and organohalide respiration (OHR) activity.

From Energy Deprivation Stress to Catalytic Adaptation of Reductive Dehalogenase TmrA for 1,1‐DCA Dechlorination: An Experimental and in Silico Study

Microbial Biotechnology, Volume 19, Issue 4, April 2026.
Adaptive evolution of Dehalobacter restrictus strain UNSWDHB under a ratio of 1:9 chloroform:1,1‐DCA regime increased 1,1‐DCA dechlorination. Sequencing and molecular dynamics simulation reveal high‐entropy tmrA mutations that improved 1,1‐DCA binding energy and stabilize the catalytic pocket, outlining a route to tune reductive dehalogenases for ...

Proteome adaptations of the organohalide-respiring Desulfitobacterium hafniense strain DCB-2 to various energy metabolisms

Frontiers in Microbiology, 2023
IntroductionDesulfitobacterium hafniense was isolated for its ability to use organohalogens as terminal electron acceptors via organohalide respiration (OHR). In contrast to obligate OHR bacteria, Desulfitobacterium spp.

Human Intestinal Microbiota Composition Shapes Model Polyfluoroalkyl Substance Biotransformation

ChemBioChem, Volume 27, Issue 5, 13 March 2026.
Differences in the human gut microbiome impact the rate and pathway of biotransformation for 6:2 polyfluoroalkyl phosphate diester (diPAP), a model polyfluoroalkyl substance. Metabolic analysis is coupled to 16S RNA analysis to identify correlations between microbial taxa abundance and PAP transformation products not previously established from ...

Biomarkers’ Responses to Reductive Dechlorination Rates and Oxygen Stress in Bioaugmentation Culture KB-1TM

Microorganisms, 2018
Using mRNA transcript levels for key functional enzymes as proxies for the organohalide respiration (OHR) rate, is a promising approach for monitoring bioremediation populations in situ at chlorinated solvent-contaminated field sites.

Effect of Moderate Heat on TCE Reductive Dechlorination Rates in Groundwater

Groundwater Monitoring &Remediation, Volume 46, Issue 2, Page 44-54, Spring 2026.
Abstract Low‐temperature heating (in the mesophilic range of ~15 to 40 °C) of contaminated aquifers offers the prospect of increasing the rates for biotic and abiotic treatment of volatile organic compounds. Thermal In Situ Sustainable Remediation (TISR®) is one of the approaches available to implement low temperature heating.

Cobalamin‐Dependent Aryl Methyl Ether O‐Demethylases: Promising Enzymes for Biocatalytic Applications from Lignin Valorization to Organic Synthesis

ChemCatChem, Volume 17, Issue 21, November 10, 2025.
Cobalamin‐dependent aryl methyl ether O‐demethylases have high potential for biocatalytic applications, including lignin valorization and synthetic chemistry. In this review, we provide a detailed overview of such O‐demethylase systems identified to date from various microorganisms, including their mechanism, substrate scope and selectivity, and ...

Characterization of the electron-accepting part of the organohalide respiration chain of Dehalobacter and Desulfitobacterium [PDF]

, 2022
Organohalide respiration (OHR) is a bacterial anaerobic process that use halogenated compounds, e.g. tetrachloroethene (PCE), as terminal electron acceptors. D. restrictus strain PER-K23, an obligate OHR bacterium (OHRB), and D.
