Dehalococcoides and Reductive Dechlorination of Chlorinated Solvents

2012
Since the beginning of the twentieth century, short-chain C1 to C3 chlorinated aliphatic hydrocarbons (CAHs) have been manufactured in large amounts and extensively used in industrial, military, agricultural and household applications. The widespread use of CAHs is based on their desirable properties including low cost, easy availability, excellence as

Microbial Monitoring During Bioaugmentation with Dehalococcoides

2012
Molecular biological tools (MBTs) measure specific biomarkers that are indicators of the ability of bacteria to degrade specific contaminants. Among all MBTs, application of nucleic acid-based tools is the most advanced, and specific tests for the presence and abundance of key dechlorinating (i.e., Dehalococcoides) bacteria, as well as other key ...

Production and Handling of Dehalococcoides Bioaugmentation Cultures

2012
In its infancy, bioaugmentation technology suffered from overselling and a lack of efficacy data to confirm its reliability. Its more recent application for treating chlorinated solvents, however, has become an accepted and proven remedial technology with many hundreds of successful applications performed to date.

Kinetics of dechlorination by Dehalococcoides mccartyi using different carbon sources

Journal of Contaminant Hydrology, 2014
Stimulated anaerobic dechlorination is generally considered a valuable step for the remediation of aquifers polluted with chlorinated ethenes (CEs). Correct simulation and prediction of this process in situ, however, require good knowledge of the associated biological reactions.

Predominance of Dehalococcoides in the presence of different sulfate concentrations

Water, Air, & Soil Pollution, 2013
This is the first study that investigates in detail the effect of different sulfate concentrations on trichloroethene-dechlorinating microbial communities, both in terms of dechlorinating performance andmicrobial composition. The study used a series of Dehalococcoidescontaining trichloroethene-dechlorinating microbial communities, which operated for ...

The Genus Dehalococcoides

2016
Dehalococcoides, now called Dehalococcoides mccartyi, was first discovered in an enrichment culture from sewage sludge that reductively dechlorinated the groundwater pollutants tetrachloroethene (PCE) and trichloroethene (TCE) to vinyl chloride (VC) and ethene, in contrast to other organohalide-respiring bacteria that dechlorinated PCE and TCE only as ...

Mechanistic insight into the Dehalococcoides -mediated reductive dechlorination of polychlorinated biphenyls

Physical Chemistry Chemical Physics, 2023
Microbial reductive dechlorination provides a green and highly desirable approach to address the pollution raised by the substantial legacies of polychlorinated biphenyls (PCBs) in soil, sediment, and underground water.

Dechlorinating performance of Dehalococcoides spp. mixed culture enhanced by tourmaline

Chemosphere, 2018
Dehalococcoides spp. were extensively studied and applied to in-situ trichloroethylene (TCE) remediation since it is the only genus that can reduce TCE to harmless ethene completely. However, this technology was hindered because of the requirement of electron donor (i.e. hydrogen or fermentable organic substrate).

Anaerobic biotransformation of hexachlorocyclohexane isomers by Dehalococcoides species and an enrichment culture

Biodegradation, 2018
The biotransformation of hexachlorocyclohexane isomers (HCH) by two Dehalococcoides mccartyi strains (195 and BTF08) and an enrichment culture was investigated and compared to conversion by the obligate anaerobic strain Clostridium pasteurianum strain DSMZ 525. The D.

Influence of humic acid on the trichloroethene degradation by Dehalococcoides-containing consortium

Journal of Hazardous Materials, 2011
By taking an anaerobic Dehalococcoides-containing consortium (designated UC-1) as the research object, the influence of humic acid on the degradation of TCE by UC-1 was examined. The results indicated that (i) TCE was more rapidly degraded in the presence of humic acid compared with the control and the TCE removal efficiencies increased with the ...
