Selective enrichment yields robust ethene-producing dechlorinating cultures from microcosms stalled at cis-dichloroethene. [PDF]

PLoS ONE, 2014
Dehalococcoides mccartyi strains are of particular importance for bioremediation due to their unique capability of transforming perchloroethene (PCE) and trichloroethene (TCE) to non-toxic ethene, through the intermediates cis-dichloroethene (cis-DCE ...

Microbial Community Dynamics in Marine Water: Influence of Hydrocarbon Type and Exposure Time

Environmental Toxicology, Volume 41, Issue 11, Page 1265-1276, November 2026.
ABSTRACT Marine environments are frequently impacted by petroleum‐derived hydrocarbons, which pose ecological risks because of their toxic, mutagenic, and carcinogenic potential. Microorganisms play a crucial role in hydrocarbon degradation, and understanding the influence of time and hydrocarbon type on microbial dynamics helps improve bioremediation ...

Overview of organohalide-respiring bacteria and a proposal for a classification system for reductive dehalogenases [PDF]

Philosophical Transactions of the Royal Society B: Biological Sciences, 2013
Organohalide respiration is an anaerobic bacterial respiratory process that uses halogenated hydrocarbons as terminal electron acceptors during electron transport-based energy conservation. This dechlorination process has triggered considerable interest for detoxification of anthropogenic groundwater contaminants.

Bioorthogonal Chemistry in Neurobiology: From Imaging to Proteomics

ChemBioChem, Volume 27, Issue 20, 28 October 2026.
This review highlights emerging strategies for labeling neuronal proteins, enabling visualization and quantitative analysis of their expression, localization, and dynamics. By combining genetic code expansion (GCE), metabolic labeling, and click chemistry‐based labeling, these approaches provide powerful routes to study proteins in specific cells and ...

Multiple Nonidentical Reductive-Dehalogenase-Homologous Genes Are Common in Dehalococcoides [PDF]

Applied and Environmental Microbiology, 2004
ABSTRACT Degenerate primers were used to amplify large fragments of reductive-dehalogenase-homologous (RDH) genes from genomic DNA of two Dehalococcoides populations, the chlorobenzene- and dioxin-dechlorinating strain CBDB1 and the trichloroethene-dechlorinating strain FL2.

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 ...

Predicting Functional Diversity Within Enzyme Families: A Practical Perspective

ChemBioChem, Volume 27, Issue 19, 14 October 2026.
Integrating machine learning into enzyme discovery requires navigating the trade‐offs between data quantity and quality. This article provides a best‐practice framework for developing robust predictors, focusing on mitigating bias in biochemical datasets, implementing systematic “cold‐drug” validation strategies, and utilizing explainable artificial ...

Investigations on a chloroform reductive dehalogenase

, 2017
Halogenated organic compounds (organohalides) are globally prevalent, recalcitrant toxic and carcinogenic environmental pollutants contaminating soil and groundwater. Organohalide respiring bacteria provide a potential solution to remediate contaminated sites, as they are capable of utilising organohalides as electron acceptors for the generation of ...

Unveiling organohalide respiration potential in River Nile sediments via 16S rRNA gene amplicon sequencing of endogenous bacterial communities

BMC Microbiology
Background Industrial waste, agricultural runoff and untreated sewage contaminate the Nile, leaving a toxic legacy in its sediments. Organohalides-polluted sediment in particular poses serious public health risks and detrimental effects on aquatic life ...
