Enumeration of Organohalide Respirers in Municipal Wastewater Anaerobic Digesters [PDF]
Microbiology Insights, 2015 Organohalide contaminants such as triclosan and triclocarban have been well documented in municipal wastewater treatment plants (WWTPs), but the degradation of these contaminants is not well understood. One possible removal mechanism is organohalide respiration by which bacteria reduce the halogenated compound.

Frontiers in Microbiology, 2019 Organohalide-respiring bacteria have been linked to the cycling and possible respiration of chlorinated natural organic matter (Cl-NOM) in uncontaminated soils and sediments. The importance of non-respiratory hydrolytic/oxidative dechlorination processes

Organohalide respiration in pristine environments: implications for the natural halogen cycle [PDF]
Environmental Microbiology, 2017 Summary Halogenated organic compounds, also termed organohalogens, were initially considered to be of almost exclusively anthropogenic origin. However, over 5000 naturally synthesized organohalogens are known today. This has also fuelled the hypothesis that the natural and ancient origin of organohalogens could have primed development

Microorganisms, 2020 Reductive dehalogenases are responsible for the reductive cleavage of carbon-halogen bonds during organohalide respiration. A variety of mechanisms have been proposed for these cobalamin and [4Fe-4S] containing enzymes, including organocobalt, radical ...

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.

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.

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.

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 ...

Detection of Organohalide-Respiring Enzyme Biomarkers at a Bioaugmented TCE-Contaminated Field Site
Frontiers in Microbiology, 2019 RNA-based biomarkers have been successfully detected at field sites undergoing in situ bioremediation, but the detection of expressed enzymes is a more direct way to prove activity for a particular biocatalytic process of interest since they provide ...
