Preparation and characterization of site-specific dechlorinating microbial inocula capable of complete dechlorination enriched in anaerobic microcosms amended with clay mineral [PDF]
, 2020 Short-chain halogenated aliphatic hydrocarbons (e.g. perchloroethene, trichloroethene) are among the most toxic environmental pollutants. Perchloroethene and trichloroethene can be dechlorinated to non-toxic ethene through reductive dechlorination by ...

Cobamide-mediated enzymatic reductive dehalogenation via long-range electron transfer
Nature Communications, 2017 Cobalamin-containing reductive dehalogenases from organohalide-respiring bacteria play a key role in the degradation of halogenated organic compounds. Here the authors proposed a catalytic mechanism for dehalogenation that relies on a long-range electron

Experimental validation of in silico model-predicted isocitrate dehydrogenase and phosphomannose isomerase from Dehalococcoides mccartyi [PDF]
, 2015 Gene sequences annotated as proteins of unknown or non-specific function and hypothetical proteins account for a large fraction of most genomes. In the strictly anaerobic and organohalide respiring Dehalococcoides mccartyi, this lack of annotation ...

Microbial Community Response of an Organohalide Respiring Enrichment Culture to Permanganate Oxidation. [PDF]
PLoS ONE, 2015 While in situ chemical oxidation is often used to remediate tetrachloroethene (PCE) contaminated locations, very little is known about its influence on microbial composition and organohalide respiration (OHR) activity.
