Coupling Bioflocculation of Dehalococcoides mccartyi to High-Rate Reductive Dehalogenation of Chlorinated Ethenes

Environmental Science & Technology, 2017
Continuous bioreactors operated at low hydraulic retention times have rarely been explored for reductive dehalogenation of chlorinated ethenes. The inability to consistently develop such bioreactors affects the way growth approaches for Dehalococcoides mccartyi bioaugmentation cultures are envisioned.

Enhanced resilience to oxygen exposure and toxicity of chlorinated solvents in immobilized Dehalococcoides mccartyi

Journal of Hazardous Materials
Members of Dehalococcoides mccartyi (Dhc) are strictly anaerobic and play crucial roles in the restoration of many industrial sites impacted by chlorinated solvents, such as tetrachloroethene (PCE) and trichloroethene (TCE). In situ bioremediation with Dhc involves intricate procedures intended to minimize oxygen intrusion, and achieving optimal ...

Identification of a Chlorodibenzo-p-dioxin Dechlorinating Dehalococcoides mccartyi by Stable Isotope Probing

Environmental Science & Technology, 2019
Polychlorinated dibenzo-p-dioxins (PCDDs) are released into the environment from a variety of both anthropogenic and natural sources. While highly chlorinated dibenzo-p-dioxins are persistent under oxic conditions, in anoxic environments, these organohalogens can be reductively dechlorinated to less chlorinated compounds that are then more amenable to ...

Genomic Characterization of Dehalococcoides mccartyi Strain JNA That Reductively Dechlorinates Tetrachloroethene and Polychlorinated Biphenyls

Environmental Science & Technology, 2015
Dehalococcoides mccartyi strain JNA detoxifies highly chlorinated polychlorinated biphenyl (PCB) mixtures via 85 distinct dechlorination reactions, suggesting that it has great potential for PCB bioremediation. However, its genomic and functional gene information remain unknown due to extremely slow growth of strain JNA with PCBs.

Mechanistic insights into chloroethene dechlorination by Dehalococcoides mccartyi strain CWV2: A multi-omics perspective

Water Research
This study provides an in-depth investigation of the novel Dehalococcoides mccartyi (Dhc) strain CWV2, isolated from Taiwan, for its effectiveness in dechlorinating various chloroethenes, including PCE, TCE, DCEs, and VC, to ethene. Through multi-omics analyses, including genomic, transcriptomic, translatomic and proteomic profiling, we uncovered the ...

Anaerobic transformation of brominated aromatic compounds by Dehalococcoides mccartyi strain CBDB1

2017
Bromierte Flammschutzmittel sind weit verbreitete Verbindungen die in unserem täglichen Leben im Bereich des Brandschutzes eingesetzt werden. Für viele von ihnen wurde berichtet, dass sie für den Menschen giftig sein könnten. Zudem wurden sie häufig als Schadstoffe in der Umwelt identifiziert. Dehalococcoides mccartyi Stämme können nur über Organohalid-

Comprehensive exploration of the anaerobic biotransformation of polychlorinated biphenyls in Dehalococcoides mccartyi CG1: Kinetics, enantioselectivity, and isotope fractionation

Environmental Pollution
Anaerobic microbial transformation is a key pathway in the natural attenuation of polychlorinated biphenyls (PCBs). Much less is known about the transformation behaviors induced by pure organohalide-respiring bacteria, especially kinetic isotope effects.
