Bioaugmentation with DistinctDehalobacterStrains Achieves Chloroform Detoxification in Microcosms

Environmental Science & Technology, 2014
Chloroform (CF) is a widespread groundwater contaminant not susceptible to aerobic degradation. Under anoxic conditions, CF can undergo abiotic and cometabolic transformation but detoxification is generally not achieved. The recent discovery of distinct Dehalobacter strains that respire CF to dichloromethane (DCM) and ferment DCM to nonchlorinated ...

Anaerobic mineralization of 2,4,6-tribromophenol to CO2 by a synthetic microbial community comprising Clostridium, Dehalobacter, and Desulfatiglans.

Bioresource Technology, 2015
Anaerobic mineralization of 2,4,6-tribromophenol (2,4,6-TBP) was achieved by a synthetic anaerobe community comprising a highly enriched culture of Dehalobacter sp. phylotype FTH1 acting as a reductive debrominator; Clostridium sp. strain Ma13 acting as a hydrogen supplier via glucose fermentation; and a novel 4-chlorophenol-degrading anaerobe ...

Isolation and characterization of a novel Dehalobacter species strain TCP1 that reductively dechlorinates 2,4,6-trichlorophenol

Biodegradation, 2014
Chlorophenols are widely used as biocides, leading them to being prevalent environmental contaminants that pose toxic threats to ecosystems. In this study, a Dehalobacter species strain TCP1 was isolated from a digester sludge sample, which is able to dechlorinate 2,4,6-trichlorophenol (2,4,6-TCP) to 4-monochlorophenol (4-MCP) with H2 as the sole ...

Chloroform respiration to dichloromethane by a Dehalobacter population

Environmental Microbiology, 2010
Summary Chloroform (CF), or trichloromethane, is an ubiquitous environmental pollutant because of its widespread industrial use, historically poor disposal and recalcitrance to biodegradation. Chloroform is a potent inhibitor of metabolism and no known organism uses it as a growth substrate.

A Role for Dehalobacter spp. in the Reductive Dehalogenation of Dichlorobenzenes and Monochlorobenzene

Environmental Science & Technology, 2011
Previously, we demonstrated the reductive dehalogenation of dichlorobenzene (DCB) isomers to monochlorobenzene (MCB), and MCB to benzene in sediment microcosms derived from a chlorobenzene-contaminated site. In this study, enrichment cultures were established for each DCB isomer and each produced MCB and trace amounts of benzene as end products.

Dichloromethane Fermentation by a Dehalobacter sp. in an Enrichment Culture Derived from Pristine River Sediment [PDF]

Applied and Environmental Microbiology, 2012
ABSTRACT Dichloromethane (DCM) as the sole substrate supported growth of a Dehalobacter sp. in an enrichment culture derived from noncontaminated river sediment. DCM was not reductively dechlorinated, and acetate was produced, indicating DCM fermentation and further suggesting Dehalobacter

Reductive Dechlorination of Polychlorinated Biphenyls and Dibenzo-p-Dioxins in an Enrichment Culture Containing Dehalobacter Species

Microbes and Environments, 2009
The dechlorination of polychlorinated biphenyls (PCBs) and polychlorinated dibenzo-p-dioxins was examined in an enrichment culture (KFL culture) that contained two phylotypes of Dehalobacter, FTH1 and FTH2. The KFL culture dechlorinated 2,3,4,5-tetrachlorobiphenyl, 2,3,4-trichorobiphenyl (2,3,4-TriCB), and 1,2,3-trichlorodibenzo-p-dioxin (1,2,3-TriCDD).

Large Carbon Isotope Fractionation during Biodegradation of Chloroform by Dehalobacter Cultures

Environmental Science & Technology, 2012
Compound specific isotope analysis (CSIA) has been applied to monitor bioremediation of groundwater contaminants and provide insight into mechanisms of transformation of chlorinated ethanes. To date there is little information on its applicability for chlorinated methanes.

Dehalobacter alkaniphilus sp. nov.

Through pangenomic analyses we have found two new multi-strain species of Dehalobacter, in addition to the previously validly published Dehalobacter restrictus. The two species currently have placeholder names in the GTDB, thus we proposed these new species names instead.
