Mechanistic insight into co-metabolic dechlorination of hexachloro-1,3-butadiene in Dehalococcoides

, 2022
Hexachloro-1,3-butadiene (HCBD) as one of emerging persistent organic pollutants (POPs) poses potential risk to human health and ecosystems. Organohalide-respiring bacteria (OHRB)-mediated reductive dehalogenation represents a promising strategy to ...

Isolation and genomic characterization of a Dehalococcoides strain suggests genomic rearrangement during culture

Scientific Reports, 2017
We have developed and characterized a bacterial consortium that reductively dechlorinates trichloroethene to ethene. Quantitative PCR analysis for the 16S rRNA and reductive dehalogenase genes showed that the consortium is highly enriched with ...

Molecular signatures for members of the genus Dehalococcoides and the class Dehalococcoidia

International Journal of Systematic and Evolutionary Microbiology, 2014
The bacteria belonging to the class Dehalococcoidia , due to their ability to dehalogenate chlorinated compounds, are of much interest for bioremediation of contaminated sites.

Resilience and recovery of Dehalococcoides mccartyi following low pH exposure [PDF]

FEMS Microbiology Ecology, 2017
Bioremediation treatment (e.g. biostimulation) can decrease groundwater pH with consequences for Dehalococcoides mccartyi (Dhc) reductive dechlorination activity. To explore the pH resilience of Dhc, the Dhc-containing consortium BDI was exposed to pH 5.5 for up to 40 days. Following 8- and 16-day exposure periods to pH 5.5, dechlorination activity and

Homoacetogenesis in Deep-Sea Chloroflexi, as Inferred by Single-Cell Genomics, Provides a Link to Reductive Dehalogenation in Terrestrial Dehalococcoidetes

mBio, 2017
The deep marine subsurface is one of the largest unexplored biospheres on Earth and is widely inhabited by members of the phylum Chloroflexi. In this report, we investigated genomes of single cells obtained from deep-sea sediments of the Peruvian Margin,

Iron Sulfide Enhanced the Dechlorination of Trichloroethene by Dehalococcoides mccartyi Strain 195

Frontiers in Microbiology, 2021
Iron sulfide (FeS) nanoparticles have great potential in environmental remediation. Using the representative species Dehalococcoides mccartyi strain 195 (Dhc 195), the effect of FeS on trichloroethene (TCE) dechlorination was studied with hydrogen and ...

Rapid Enrichment of Dehalococcoides-Like Bacteria by Partial Hydrophobic Separation [PDF]

Applied and Environmental Microbiology, 2017
ABSTRACT Organohalide-respiring bacteria can be difficult to enrich and isolate, which can limit research on these important organisms. The goal of this research was to develop a method to rapidly (minutes to days) enrich these organisms from a mixed community.

Detection of Organohalide-Respiring Enzyme Biomarkers at a Bioaugmented TCE-Contaminated Field Site

Frontiers in Microbiology, 2019
RNA-based biomarkers have been successfully detected at field sites undergoing in situ bioremediation, but the detection of expressed enzymes is a more direct way to prove activity for a particular biocatalytic process of interest since they provide ...

Bioelectrochemical single reactor for reductive and oxidative removal of trichloroethylene from contaminated groundwater

Journal of Chemical Technology &Biotechnology, Volume 101, Issue 11, Page 2268-2275, November 2026.
Abstract BACKGROUND Chlorinated aliphatic hydrocarbons such as trichloroethylene (TCE) are persistent groundwater contaminants due to improper disposal and low biodegradability. This work presents an innovative bioelectrochemical system for the integrated reductive/oxidative removal of TCE from contaminated water, implemented in a single tubular ...
