PCE dechlorination by non-Dehalococcoides in a microbial electrochemical system

Journal of Industrial Microbiology and Biotechnology, 2016
Abstract The bioremediation of tetrachloroethene (perchloroethene; PCE) contaminated sites generally requires a supply of some fermentable organic substrates as an electron donor. On the other hand, organic substrates can induce the massive growth of microorganisms around the injection wells, which can foul the contaminated subsurface ...

Role of bicarbonate as a pH buffer and electron sink in microbial dechlorination of chloroethenes

Microbial Cell Factories, 2012
Background Buffering to achieve pH control is crucial for successful trichloroethene (TCE) anaerobic bioremediation. Bicarbonate (HCO3−) is the natural buffer in groundwater and the buffer of choice in the laboratory and at contaminated sites undergoing ...

A Metagenome-based Examination of Dechlorinating Enrichment Cultures: Dehalococcoides and the Role of the Non-dechlorinating Microorganisms.

, 2012
Bioremediation of chlorinated solvents to a non-toxic end product can be achieved with Dehalococcoides sp., through reductive dehalogenation of the chlorinated organics. Dehalococcoides sp.

Oxygen Effect on Dehalococcoides Viability and Biomarker Quantification

, 2016
Oxygen-sensitive Dehalococcoides bacteria play crucial roles in detoxification of chlorinated contaminants (e.g., chlorinated ethenes), and bioremediation monitoring relies on quantification of Dehalococcoides DNA and RNA biomarkers.

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

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 ...

Whole metagenome sequencing and 16S rRNA gene amplicon analyses reveal the complex microbiome responsible for the success of enhanced in-situ reductive dechlorination (ERD) of a tetrachloroethene-contaminated Superfund site.

PLoS ONE
The North Railroad Avenue Plume (NRAP) Superfund site in New Mexico, USA exemplifies successful chlorinated solvent bioremediation. NRAP was the result of leakage from a dry-cleaning that operated for 37 years.
