Genomic, transcriptomic and proteomic analyses of Dehalobacter UNSWDHB in response to chloroform.

Environmental Microbiology Reports, 2016
Summary Organohalide respiring bacteria (ORB) are capable of utilising organohalides as electron acceptors for the generation of cellular energy and consequently play an important role in the turnover of natural and anthropogenically‐derived organohalides.

Dehalogenation of chlorobenzenes, dichlorotoluenes, and tetrachloroethene by three Dehalobacter spp.

Environmental Science & Technology, 2014
Three enrichment cultures containing Dehalobacter spp. were developed that dehalogenate each of the dichlorobenzene (DCB) isomers to monochlorobenzene (MCB), and the strains using 1,2-DCB (12DCB1) or 1,3-DCB (13DCB1) are now considered isolated, whereas the strain using 1,4-DCB (14DCB1) is considered highly enriched.

Bioaugmentation with distinct Dehalobacter strains 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 ...

Isolation and characterization of Dehalobacter sp. strain UNSWDHB capable of chloroform and chlorinated ethane respiration.

Environmental Microbiology, 2016
Summary Dehalobacter sp. strain UNSWDHB can dechlorinate up to 4 mM trichloromethane at a rate of 0.1 mM per day to dichloromethane and 1,1,2‐trichloroethane (1 mM, 0.1 mM per day) with the unprecedented product profile of 1,2‐dichloroethane and vinyl chloride.

A Multifunctional Dehalobacter ? Tandem Chloroform and Dichloromethane Degradation in a Mixed Microbial Culture

Environmental Science & Technology, 2023
Chloroform (CF) and dichloromethane (DCM) contaminate groundwater sites around the world but can be cleaned up through bioremediation. Although several strains of Dehalobacter restrictus can reduce CF to DCM and multiple Peptococcaceae can ferment DCM, these processes cannot typically happen simultaneously due to CF sensitivity in the known DCM ...

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.

Involvement of Dehalobacter strains in the anaerobic dechlorination of 2,4,6-trichlorophenol

Journal of Bioscience and Bioengineering, 2013
A culture reductively dechlorinating 2,4,6-trichlorophenol (TCP) was enriched from a sediment contaminated with chlorinated aliphatic hydrocarbons. The culture dechlorinated 100 μM of 2,4,6-TCP to 4-chlorophenol within 15 days utilizing H2 and a yeast extract as an electron donor and carbon source, respectively.

Relative contributions of Dehalobacter and zerovalent iron in the degradation of chlorinated methanes.

Environmental Science & Technology, 2015
The role of bacteria and zerovalent iron (Fe(0)) in the degradation of chlorinated solvents in subsurface environments is of interest to researchers and remediation practitioners alike. Fe(0) used in reactive iron barriers for groundwater remediation positively interacted with enrichment cultures containing Dehalobacter strains in the transformation of

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 ...
