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 ...

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.

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.

Microbial Debromination of Polybrominated Diphenyl Ethers by Dehalococcoides-Containing Enrichment Culture

Frontiers in Microbiology, 2022
Polybrominated diphenyl ethers (PBDEs), commonly used as flame retardants in a wide variety of consumer products, are emerging persistent pollutants and ubiquitously distributed in the environment.

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.

Functional Genes and Bacterial Communities During Organohalide Respiration of Chloroethenes in Microcosms of Multi-Contaminated Groundwater

Frontiers in Microbiology, 2019
Microcosm experiments with CE-contaminated groundwater from a former industrial site were set-up to evaluate the relationships between biological CE dissipation, dehalogenase genes abundance and bacterial genera diversity.
