Bioelectrochemically-assisted degradation of chloroform by a co-culture of Dehalobacter and Dehalobacterium [PDF]

Environmental Science and Ecotechnology, 2022
Using bioelectrochemical systems (BESs) to provide electrochemically generated hydrogen is a promising technology to provide electron donors for reductive dechlorination by organohalide-respiring bacteria.

Modeling reveals a metabolic basis of competition among Dehalobacter strains during tandem chloroform and dichloromethane metabolism [PDF]

mSystems
SC05-UT is an anaerobic, heterogenous microbial enrichment culture that reduces chloroform to dichloromethane through reductive dechlorination, which it further mineralizes to carbon dioxide.

Vitamin B12 as a source of variability in isotope effects for chloroform biotransformation by Dehalobacter [PDF]

MicrobiologyOpen
Carbon and chlorine isotope effects for biotransformation of chloroform by different microbes show significant variability. Reductive dehalogenases (RDase) enzymes contain different cobamides, affecting substrate preferences, growth yields, and ...

Functional genomics of corrinoid starvation in the organohalide-respiring bacterium Dehalobacter restrictus strain PER-K23 [PDF]

Frontiers in Microbiology, 2015
De novo corrinoid biosynthesis represents one of the most complicated metabolic pathways in nature. Organohalide-respiring bacteria (OHRB) have developed different strategies to deal with their need of corrinoid, as it is an essential cofactor of ...

Sister Dehalobacter Genomes Reveal Specialization in Organohalide Respiration and Recent Strain Differentiation Likely Driven by Chlorinated Substrates

Frontiers in Microbiology, 2016
The genomes of two closely related Dehalobacter strains (strain CF and strain DCA) were assembled from the metagenome of an anaerobic enrichment culture that reductively dechlorinates chloroform (CF), 1,1,1-trichloroethane (1,1,1-TCA) and 1,1 ...

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

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.

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

Complete genome sequence of Dehalobacter restrictus PER-K23T [PDF]

Standards in Genomic Sciences, 2013
Dehalobacter restrictus strain PER-K23 (DSM 9455) is the type strain of the species Dehalobacter restrictus. D. restrictus strain PER-K23 grows by organohalide respiration, coupling the oxidation of H2 to the reductive dechlorination of tetra- or trichloroethene.

Deciphering reductive dehalogenase specificity through targeted mutagenesis of chloroalkane reductases [PDF]

Applied and Environmental Microbiology
Reductive dehalogenases (RDases) are essential in the anaerobic degradation of various organohalide contaminants. This family of enzymes has broad sequence diversity, but high structural conservation. There have been few studies assessing how RDase amino
