Enumeration of Organohalide Respirers in Municipal Wastewater Anaerobic Digesters [PDF]

Microbiology Insights, 2015
Organohalide contaminants such as triclosan and triclocarban have been well documented in municipal wastewater treatment plants (WWTPs), but the degradation of these contaminants is not well understood. One possible removal mechanism is organohalide respiration by which bacteria reduce the halogenated compound.

Geochemical and microbial community determinants of reductive dechlorination at a site biostimulated with glycerol [PDF]

, 2016
Biostimulation is widely used to enhance reductive dechlorination of chlorinated ethenes in contaminated aquifers. However, the knowledge on corresponding biogeochemical responses is limited. In this study glycerol was injected in an aquifer contaminated

Presence, Diversity, and Enrichment of Respiratory Reductive Dehalogenase and Non-respiratory Hydrolytic and Oxidative Dehalogenase Genes in Terrestrial Environments

Frontiers in Microbiology, 2019
Organohalide-respiring bacteria have been linked to the cycling and possible respiration of chlorinated natural organic matter (Cl-NOM) in uncontaminated soils and sediments. The importance of non-respiratory hydrolytic/oxidative dechlorination processes

Transcriptional regulation of tetrachloroethene respiration in Sulfurospirillum species [PDF]

, 2020
Energy conservation via organohalide respiration (OHR), comprising the reductive dehalogenation of halogenated organic compounds, is an inducible process in OHR capable Sulfurospirillum species.

Catabolic Reductive Dehalogenase Substrate Complex Structures Underpin Rational Repurposing of Substrate Scope

Microorganisms, 2020
Reductive dehalogenases are responsible for the reductive cleavage of carbon-halogen bonds during organohalide respiration. A variety of mechanisms have been proposed for these cobalamin and [4Fe-4S] containing enzymes, including organocobalt, radical ...

An integrative overview of genomic, transcriptomic and proteomic analyses in organohalide respiration research

FEMS Microbiology Ecology, 2018
Organohalide respiration (OHR) is a crucial process in the global halogen cycle and of interest for bioremediation. However, investigations on OHR are hampered by the restricted genetic accessibility and the poor growth yields of many organohalide ...

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 ...

Organohalide-Respiring Deltaproteobacteria

, 2016
Organohalide respiration was first discovered in the deltaproteobacterium Desulfomonile tiedjei, which used 3-chlorobenzoate as the respiratory electron acceptor. Since this breakthrough discovery, the organohalide-respiring phenotype was demonstrated in 6 out of the 21 currently published families of the class Deltaproteobacteria.
