Organohalide Respiring Bacteria and Reductive Dehalogenases: Key Tools in Organohalide Bioremediation

Frontiers in Microbiology, 2016
Organohalides are recalcitrant pollutants that have been responsible for substantial contamination of soils and groundwater. Organohalide-respiring bacteria (ORB) provide a potential solution to remediate contaminated sites, through their ability to use ...

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.

Comparative proteogenomics reveals ecological and evolutionary insights into the organohalide-respiring Dehalobacter restrictus strain T

Applied and Environmental Microbiology
1,1,1-Trichloroethane (1,1,1-TCA) and chloroform (CF) are persistent groundwater contaminants because of their widespread industrial use as organic solvents and improper disposal in the past.

Roles of Organohalide-Respiring Dehalococcoidia in Carbon Cycling

mSystems, 2020
The class Dehalococcoidia within the Chloroflexi phylum comprises the obligate organohalide-respiring genera Dehalococcoides, Dehalogenimonas, and “Candidatus Dehalobium.” Knowledge of the unique ecophysiology and biochemistry of Dehalococcoidia has been

Structure of a membrane-bound menaquinol:organohalide oxidoreductase

Nature Communications, 2023
Organohalide-respiring bacteria are key organisms for the bioremediation of soils and aquifers contaminated with halogenated organic compounds. The major players in this process are respiratory reductive dehalogenases, corrinoid enzymes that use ...

Hybrid Transcriptional Regulators for the Screening of Target DNA Motifs in Organohalide-Respiring Bacteria

Frontiers in Microbiology, 2020
The bioremediation of persistent organohalide molecules under anoxic conditions mostly relies on the bacterial process called organohalide respiration (OHR).

Resilience and functional redundancy of methanogenic digestion microbiome safeguard recovery of methanogenesis activity under the stress induced by microplastics

mLife, Volume 2, Issue 4, Page 378-388, December 2023., 2023
Abstract Microplastics and nanoplastics are emerging pollutants that substantially influence biological element cycling in natural ecosystems. Plastics are also prevalent in sewage, and they accumulate in waste‐activated sludge (WAS). However, the impacts of plastics on the methanogenic digestion of WAS and the underpinning microbiome remain ...

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
