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

A review in the current developments of genus Dehalococcoides, its consortia and kinetics for bioremediation options of contaminated groundwater

Sustainable Environment Research, 2018
This article reviews the current developments in genus Dehalococcoides as key dechlorinating bacteria in chlorinated ethene contaminated sites. The presence of chlorinated ethenes in environment had been a concern for more than five decades as it ...

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.

Addition of Shewanella oneidensis MR-1 to the Dehalococcoides-containing culture enhances the trichloroethene dechlorination

Environment International, 2019
Dehalococcoides is able to completely dehalogenate tetrachloroethene (PCE) and trichloroethene (TCE) to ethene (ETH). However, the dechlorination efficiency of Dehalococcoides is low and result in the accumulation of toxic intermediates.

Development and Characterization of a Chloroethenes-Dechlorinating Consortium Using Gluconate as a Hydrogen Donor

Journal of Water and Environment Technology, 2020
To evaluate the effectiveness of gluconate as a potential hydrogen donor for reductive dechlorination of chloroethenes, we developed a trichloroethene (TCE)-dechlorinating consortium from chloroethenes-contaminated groundwater containing Dehalococcoides ...

Acidophilic methanotrophs: Occurrence, diversity, and possible bioremediation applications

Environmental Microbiology Reports, Volume 15, Issue 4, Page 265-281, August 2023., 2023
Abstract Methanotrophs have been identified and isolated from acidic environments such as wetlands, acidic soils, peat bogs, and groundwater aquifers. Due to their methane (CH4) utilization as a carbon and energy source, acidophilic methanotrophs are important in controlling the release of atmospheric CH4, an important greenhouse gas, from acidic ...

Site-Specific Mobilization of Vinyl Chloride Respiration Islands by a Mechanism Common in Dehalococcoides

BMC Genomics, 2011
Background Vinyl chloride is a widespread groundwater pollutant and Group 1 carcinogen. A previous comparative genomic analysis revealed that the vinyl chloride reductase operon, vcrABC, of Dehalococcoides sp.

Comparative metagenomics of three Dehalococcoides-containing enrichment cultures: the role of the non-dechlorinating community

BMC Genomics, 2012
Background The Dehalococcoides are strictly anaerobic bacteria that gain metabolic energy via the oxidation of H2 coupled to the reduction of halogenated organic compounds. Dehalococcoides spp.

Interspecies transfer of biosynthetic cobalamin for complete dechlorination of trichloroethene by Dehalococcoides mccartyi

Water Science and Technology, 2022
Complete dechlorination of trichloroethene (TCE) by Dehalococcoides mccartyi is catalyzed by reductive dehalogenases (RDases), which possess cobalamin as the crucial cofactor. However, virtually all D. mccartyi isolated thus far are corrinoid auxotrophs.
