Dechlorination of mixed chlorinated organophosphate esters (V6 and TCEP) and associated reductive dehalogenase gene expression by Dehalococcoides mccartyi [PDF]

Applied and Environmental Microbiology
Dehalococcoides mccartyi (D. mccartyi) plays a critical role in the dechlorination of halogenated organic pollutants, yet its performance on mixed chlorinated organophosphate esters (Cl-OPEs) remains poorly understood.

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. [PDF]

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.
