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

Environ Microbiol Rep, 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 ...

From Energy Deprivation Stress to Catalytic Adaptation of Reductive Dehalogenase TmrA for 1,1-DCA Dechlorination: An Experimental and in Silico Study. [PDF]

Microb Biotechnol
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 ...

Selective enrichment yields robust ethene-producing dechlorinating cultures from microcosms stalled at cis-dichloroethene. [PDF]

PLoS ONE, 2014
Dehalococcoides mccartyi strains are of particular importance for bioremediation due to their unique capability of transforming perchloroethene (PCE) and trichloroethene (TCE) to non-toxic ethene, through the intermediates cis-dichloroethene (cis-DCE ...

Field Test of a Bioelectrochemical Membrane-Less Reactor for Chlorinated Aliphatic Hydrocarbon and Nitrate Removal from a Contaminated Groundwater. [PDF]

Chempluschem
This study evaluates a membrane‐less bioelectrochemical reactor in a real groundwater remediation scenario, targeting chlorinated aliphatic hydrocarbons and nitrate contamination. Electron supply via graphite granules biocathode stimulates reductive dechlorination and nitrate reduction, despite competing processes like sulfate reduction and ...

Characterizing the metabolism of Dehalococcoides with a constraint-based model. [PDF]

PLoS Computational Biology, 2010
Dehalococcoides strains respire a wide variety of chloro-organic compounds and are important for the bioremediation of toxic, persistent, carcinogenic, and ubiquitous ground water pollutants.

Inhibitory effects of metal ions on reductive dechlorination of polychlorinated biphenyls and perchloroethene in distinct organohalide-respiring bacteria

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.

Inferring Gene Networks for Strains of Dehalococcoides Highlights Conserved Relationships between Genes Encoding Core Catabolic and Cell-Wall Structural Proteins. [PDF]

PLoS ONE, 2016
The interpretation of high-throughput gene expression data for non-model microorganisms remains obscured because of the high fraction of hypothetical genes and the limited number of methods for the robust inference of gene networks.

Efficacy of emerging technologies in addressing reductive dechlorination for environmental bioremediation: A review

Journal of Hazardous Materials Letters, 2022
Reductive dechlorination is a core pathway of chlorination in an anaerobic environment, which can be carried out by fermentative, methanogenic, iron and sulfate-reducing microorganisms.

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

Localized plasticity in the streamlined genomes of vinyl chloride respiring Dehalococcoides. [PDF]

PLoS Genetics, 2009
Vinyl chloride (VC) is a human carcinogen and widespread priority pollutant. Here we report the first, to our knowledge, complete genome sequences of microorganisms able to respire VC, Dehalococcoides sp. strains VS and BAV1.
