Organohalide Respiration with Chlorinated Ethenes under Low pH Conditions.
Environmental Science & Technology, 2017 Bioremediation at chlorinated solvent sites often leads to groundwater acidification due to electron donor fermentation and enhanced dechlorination activity. The microbial reductive dechlorination process is robust at circumneutral pH, but activity declines at groundwater pH values below 6.0.

Organohalide respiration in pristine environments: implications for the natural halogen cycle [PDF]
Environmental Microbiology, 2018 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

Organohalide respiration: microbes breathing chlorinated molecules [PDF]
Philosophical Transactions of the Royal Society B: Biological Sciences, 2013 Bacterial respiration has taken advantage of almost every redox couple present in the environment. The reduction of organohalide compounds to release the reduced halide ion drives energy production in organohalide respiring bacteria. This process is centred around the reductive dehalogenases, an iron–sulfur and corrinoid containing family of enzymes ...

Microorganisms, 2021 The strictly anaerobic bactGIerium Dehalococcoides mccartyi obligatorily depends on organohalide respiration for energy conservation and growth. The bacterium also plays an important role in bioremediation.

ISME Communications, 2021 Obligate and non-obligate organohalide-respiring bacteria (OHRB) play central roles in the geochemical cycling and environmental bioremediation of organohalides. Their coexistence and interactions may provide functional redundancy and community stability

Environment International, 2020 Bioremediation of sites co-contaminated with organohalides and metal pollutants may have unsatisfactory performance, since metal ions can potentially inhibit organohalide respiration.

Structure of a membrane-bound menaquinol:organohalide oxidoreductase
Nature Communications, 2023 Organohalide-respiring bacteria are key organisms for the bioremediation of soils and aquifers contaminated with halogenated organic compounds. The major players in this process are respiratory reductive dehalogenases, corrinoid enzymes that use ...

Natural Niche for Organohalide-Respiring Chloroflexi [PDF]
Applied and Environmental Microbiology, 2012 ABSTRACT The phylum Chloroflexi contains several isolated bacteria that have been found to respire a diverse array of halogenated anthropogenic chemicals. The distribution and role of these Chloroflexi in uncontaminated terrestrial ...

mLife, Volume 2, Issue 4, Page 378-388, December 2023., 2023 Abstract Microplastics and nanoplastics are emerging pollutants that substantially influence biological element cycling in natural ecosystems. Plastics are also prevalent in sewage, and they accumulate in waste‐activated sludge (WAS). However, the impacts of plastics on the methanogenic digestion of WAS and the underpinning microbiome remain ...
