Reductive dechlorination of tetrachloroethene by a stepwise catalysis of different organohalide respiring bacteria and reductive dehalogenases [PDF]

Biodegradation, 2018
The enrichment culture SL2 dechlorinating tetrachloroethene (PCE) to ethene with strong trichloroethene (TCE) accumulation prior to cis-1,2-dichloroethene (cis-DCE) formation was analyzed for the presence of organohalide respiring bacteria and reductive ...

Organohalide-Respiring Bacteria at the Heart of Anaerobic Metabolism in Arctic Wet Tundra Soils. [PDF]

Appl Environ Microbiol, 2021
Once considered relevant only in contaminated sites, it is now recognized that biological chlorine cycling is widespread in natural environments. However, linkages between chlorine cycling and other ecosystem processes are not well established.

Roles of Organohalide-Respiring Dehalococcoidia in Carbon Cycling

mSystems, 2020
The class Dehalococcoidia within the Chloroflexi phylum comprises the obligate organohalide-respiring genera Dehalococcoides, Dehalogenimonas, and “Candidatus Dehalobium.” Knowledge of the unique ecophysiology and biochemistry of Dehalococcoidia has been

Diversity of organohalide respiring bacteria and reductive dehalogenases that detoxify polybrominated diphenyl ethers in E-waste recycling sites. [PDF]

ISME J, 2022
Abstract Widespread polybrominated diphenyl ethers (PBDEs) contamination poses risks to human health and ecosystems. Bioremediation is widely considered to be a less ecologically disruptive strategy for remediation of organohalide contamination, but bioremediation of PBDE-contaminated sites is limited by a lack of knowledge about PBDE ...

Genome-resolved transcriptomics reveals novel organohalide-respiring bacteria from Aarhus Bay sediments

, 2023
AbstractOrganohalide-respiring bacteria (OHRB) are keystone microbes in bioremediation of sites contaminated with organohalides and in natural halogen cycling. Known OHRB belong to distinct genera within the phylaChloroflexota,ProteobacteriaandFirmicutes, whereas information about novel OHRB mediating natural halogen cycling remains scarce.

Resilience and functional redundancy of methanogenic digestion microbiome safeguard recovery of methanogenesis activity under the stress induced by microplastics

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 ...

Incomplete Wood-Ljungdahl pathway facilitates one-carbon metabolism in organohalide-respiring Dehalococcoides mccartyi. [PDF]

, 2014
The acetyl-CoA "Wood-Ljungdahl" pathway couples the folate-mediated one-carbon (C1) metabolism to either CO2 reduction or acetate oxidation via acetyl-CoA.

Molecular insights intocobalamin-dependent enzyme systemsfrom organohalide-respiring bacteria [PDF]

, 2013
The evolution of microorganisms over millions of years has led to an impressive adaptability regarding the utilisation of different environmental conditions. The identification of bacterial species with the fascinating features to use cobalamin-dependent metalloenzymes to (i) extract energy from halogenated organic compounds (organohalides) and (ii ...

Geochemical and microbial community determinants of reductive dechlorination at a site biostimulated with glycerol [PDF]

, 2016
Biostimulation is widely used to enhance reductive dechlorination of chlorinated ethenes in contaminated aquifers. However, the knowledge on corresponding biogeochemical responses is limited. In this study glycerol was injected in an aquifer contaminated
