Effects of humic electron mediators on reductive dechlorination of polychlorinated biphenyl by consortia enriched from terrestrial and marine environments [PDF]

Frontiers in Microbiology
Humic electron mediators can facilitate the reductive dehalogenation of organohalogenated compounds by accelerating electron transfer. To investigate the effect of humic electron mediators on the microbial anaerobic reductive dechlorination of ...

Comparative Genomics of “ Dehalococcoides ethenogenes ” 195 and an Enrichment Culture Containing Unsequenced “ Dehalococcoides ” Strains [PDF]

Applied and Environmental Microbiology, 2008
ABSTRACT Tetrachloroethene (PCE) and trichloroethene (TCE) are prevalent groundwater contaminants that can be completely reductively dehalogenated by some “ Dehalococcoides ” organisms. A Dehalococcoides -organism-containing microbial consortium (referred to as ANAS) with the ...

Organic cofactors in the metabolism of Dehalococcoides mccartyi strains [PDF]

Philosophical Transactions of the Royal Society B: Biological Sciences, 2013
Dehalococcoides mccartyi strains are strictly anaerobic organisms specialized to grow with halogenated compounds as electron acceptor via a respiratory process. Their genomes are among the smallest known for free-living organisms, and the embedded gene set reflects their strong specialization.

The diversity and ecological significance of microbial traits potentially involved in B12 biosynthesis in the global ocean

mLife, Volume 2, Issue 4, Page 416-427, December 2023., 2023
Abstract Cobalamin (B12), an essential nutrient and growth cofactor for many living organisms on Earth, can be fully synthesized only by selected prokaryotes in nature. Therefore, microbial communities related to B12 biosynthesis could serve as an example subsystem to disentangle the underlying ecological mechanisms balancing the function and taxonomic

Dehalococcoides mccartyi strain NIT01 grows more stably in vessels made of pure titanium rather than the stainless alloy SUS304

Environmental Microbiology Reports, Volume 15, Issue 6, Page 557-567, December 2023., 2023
To establish large‐scale cultivation of Dehalococcoides, 7–10 litre culturing of Dehalococcoides mccartyi strain NIT01 was performed using three different vessels made of glass, stainless alloy SUS304, and titanium. The unbreakable titanium vessel demonstrated complete dechlorination of trichloroethene (TCE) to ethene, even after being reused five ...

Respiratory protein interactions in Dehalobacter sp. strain 8M revealed through genomic and native proteomic analyses

Environmental Microbiology, Volume 25, Issue 11, Page 2604-2620, November 2023., 2023
Dehalobacter can respire with chlorinated methanes (chloroform) and ethanes. Genome sequencing, proteome analyses and enzymatic assays identify TmrA as the responsible enzyme. It is organized in a larger membrane‐bound respiratory complex. RdhC, a protein encoded in the same operon, appears to be another membrane‐bound electron‐transferring protein but

Ensuring the continued success of a mulch biowall at a trichloroethylene‐contaminated superfund site: Lessons learned

Remediation Journal, Volume 33, Issue 4, Page 323-337, Fall 2023., 2023
Abstract Trichloroethylene (TCE) is a toxic organic compound, which can adversely affect human health. The chemical is one of the most frequently found contaminants in groundwater in the United States and around the world. A landfill in Maryland contaminated with high levels of TCE decades ago was added to the U.S.

Enantioselective Dechlorination of Polychlorinated Biphenyls in Dehalococcoides mccartyi CG1 [PDF]

Applied and Environmental Microbiology, 2018
A variety of agrochemicals and pharmaceuticals are chiral. Due to the enantioselectivity in biological processes, enantiomers of chiral compounds may have different environmental occurrences, fates, and ecotoxicologies. Many chiral organohalides exist in anaerobic or anoxic soils and sediments, and organohalide-respiring bacteria ...

Genome Sequence of the PCE-Dechlorinating Bacterium Dehalococcoides ethenogenes [PDF]

Science, 2005
Dehalococcoides ethenogenes is the only bacterium known to reductively dechlorinate the groundwater pollutants, tetrachloroethene (PCE) and trichloroethene, to ethene. Its 1,469,720–base pair chromosome contains large dynamic duplicated regions and integrated elements.
