Microbial Community Response of an Organohalide Respiring Enrichment Culture to Permanganate Oxidation. [PDF]

PLoS ONE, 2015
While in situ chemical oxidation is often used to remediate tetrachloroethene (PCE) contaminated locations, very little is known about its influence on microbial composition and organohalide respiration (OHR) activity.

Linking NrfD/PsrC‐like architecture to energy conservation: Functional residues in the quinone reactive QrcABCD complex of sulfate‐reducing bacteria

Protein Science, Volume 35, Issue 5, May 2026.
Abstract The QrcABCD quinone reductase complex is an electrogenic complex present in sulfate‐reducing bacteria of the Desulfobacterota phylum. It operates as a cytochrome c3:menaquinone oxidoreductase involved in electron transfer from periplasmic hydrogen or formate oxidation to the menaquinone (MK) pool.

Inferring community dynamics of organohalide-respiring bacteria in chemostats by covariance ofrdhAgene abundance [PDF]

FEMS Microbiology Ecology, 2013
We have developed a novel approach to identifying and quantifying closely related organohalide-respiring bacteria. Our approach made use of the unique genomic associations of specific reductive dehalogenase subunit A encoding genes (rdhA) that exist in known strains of Dehalococcoides mccartyi and Desulfitobacterium and the distinguishing covariance ...

Increasing in situ bioremediation effectiveness through field-scale application of molecular biological tools

Frontiers in Microbiology, 2023
Leveraging the capabilities of microorganisms to reduce (degrade or transform) concentrations of pollutants in soil and groundwater can be a cost-effective, natural remedial approach to manage contaminated sites.

Human Intestinal Microbiota Composition Shapes Model Polyfluoroalkyl Substance Biotransformation

ChemBioChem, Volume 27, Issue 5, 13 March 2026.
Differences in the human gut microbiome impact the rate and pathway of biotransformation for 6:2 polyfluoroalkyl phosphate diester (diPAP), a model polyfluoroalkyl substance. Metabolic analysis is coupled to 16S RNA analysis to identify correlations between microbial taxa abundance and PAP transformation products not previously established from ...

Effect of Moderate Heat on TCE Reductive Dechlorination Rates in Groundwater

Groundwater Monitoring &Remediation, Volume 46, Issue 2, Page 44-54, Spring 2026.
Abstract Low‐temperature heating (in the mesophilic range of ~15 to 40 °C) of contaminated aquifers offers the prospect of increasing the rates for biotic and abiotic treatment of volatile organic compounds. Thermal In Situ Sustainable Remediation (TISR®) is one of the approaches available to implement low temperature heating.

Cobalamin‐Dependent Aryl Methyl Ether O‐Demethylases: Promising Enzymes for Biocatalytic Applications from Lignin Valorization to Organic Synthesis

ChemCatChem, Volume 17, Issue 21, November 10, 2025.
Cobalamin‐dependent aryl methyl ether O‐demethylases have high potential for biocatalytic applications, including lignin valorization and synthetic chemistry. In this review, we provide a detailed overview of such O‐demethylase systems identified to date from various microorganisms, including their mechanism, substrate scope and selectivity, and ...

Effect of Sea Water Inundation on CO2 and CH4 Production of Thawing Coastal Permafrost Near Utqiaġvik, Alaska

Permafrost and Periglacial Processes, Volume 36, Issue 4, Page 787-802, October/December 2025.
ABSTRACT Rising sea levels and changing marine dynamics are increasing the inundation of previously terrestrial permafrost, accelerating thaw and altering microbial carbon cycling. On the Arctic Coastal Plain of Alaska, permafrost features like drained lake basins (DLBs) and uplands (ULs), offer distinct redox conditions and formation histories that ...

Influence of Plant Species and De‐Icing Salt on Microbial Communities in Bioretention

Environmental Microbiology Reports, Volume 17, Issue 5, October 2025.
Plant species shape bioretention bacterial and fungal communities and their associated functions, which drive system efficiency. These results underscore the importance of plant selection when designing bioretention systems. Moreover, the communities were preserved or recovered within 5 months after the exposure to NaCl levels typical of spring runoff.
