Detoxification of 1,1,2-trichloroethane to ethene in a bioreactor co-culture of Dehalogenimonas and Dehalococcoides mccartyi strains

Journal of Hazardous Materials, 2017
1,1,2-Trichloroethane (1,1,2-TCA) is a non-flammable organic solvent and common environmental contaminant in groundwater. Organohalide-respiring bacteria are key microorganisms to remediate 1,1,2-TCA because they can gain metabolic energy during its dechlorination under anaerobic conditions.

Detoxification of 1,1,2-trichloroethane to ethene by desulfitobacterium and identification of its functional reductase gene.

PLoS ONE, 2015
1,1,2-trichloroethane (1,1,2-TCA) has become a common groundwater pollutant due to historically extensive utilization, improper disposal, as well as from incomplete dechlorination of 1,1,2,2-tetrachloroethane.

Insights Into the Redox Sensitivity of Chloroflexi Hup-Hydrogenase Derived From Studies in Escherichia coli: Merits and Pitfalls of Heterologous [NiFe]-Hydrogenase Synthesis

Frontiers in Microbiology, 2018
The highly oxygen-sensitive hydrogen uptake (Hup) hydrogenase from Dehalococcoides mccartyi forms part of a protein-based respiratory chain coupling hydrogen oxidation with organohalide reduction on the outside of the cell.

Biomarkers’ Responses to Reductive Dechlorination Rates and Oxygen Stress in Bioaugmentation Culture KB-1TM

Microorganisms, 2018
Using mRNA transcript levels for key functional enzymes as proxies for the organohalide respiration (OHR) rate, is a promising approach for monitoring bioremediation populations in situ at chlorinated solvent-contaminated field sites.

Presence of Micro- and Nanoplastics Affects Degradation of Chlorinated Solvents

Toxics
Microplastics (MPs) and nanoplastics (NPs) can affect microbial abundance and activity, likely by damaging cell membrane components. While their effects on anaerobic digestion are known, less is understood about their impact on microbes involved in ...

Evaluation of the biological treatment of a real contaminated groundwater through reductive dechlorination biostimulation

Frontiers in Chemical Engineering
Chlorinated aliphatic hydrocarbons (CAHs) are common groundwater contaminants due to improper utilization in past industrial activity. Anaerobic reductive dechlorination, where bacteria use CAHs as electron acceptors, is crucial for bioremediation ...

Regulation der Organohalid-Respiration durch MarR-Regulatoren in Dehalococcoides mccartyi

, 2018
The organohalide respiration (OHR) is an important pathway for bioremidiation of halogenated anaerobic habitats. Dehalococcoides mccartyi strains are key players in that microbiological process. Reductive dehalogenases (Rdhs) reduces halogenated compounds.
