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 ...

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.

Biogeochemical characterization of micritized carbonate grains in the shallow‐marine Al‐Kharrar Lagoon (Red Sea, Saudi Arabia)

Sedimentology, Volume 72, Issue 5, Page 1593-1619, August 2025.
ABSTRACT Micritization of marine carbonate grains is an early diagenetic process involving the alteration of the original carbonate fabric and the formation of cryptocrystalline textures through cycles of dissolution and reprecipitation. Microorganisms play a significant role in this process, actively contributing to the formation of constructive and ...

Diversity of Cobalamin Riboswitches in the Corrinoid-Producing Organohalide Respirer Desulfitobacterium hafniense [PDF]

Journal of Bacteriology, 2013
ABSTRACTThe strategic adaptation of prokaryotes in polluted niches involves the efficient regulation of their metabolism. The obligate anaerobe and metabolically versatileDesulfitobacterium hafniensereductively dechlorinates halogenated organic compounds (so-called organohalides). SomeD.

Dehalococcoides mccartyi strain CBDB1 takes up protons from the cytoplasm to reductively dehalogenate organohalides indicating a new modus of proton motive force generation

Frontiers in Microbiology, 2023
Proton translocation across the cytoplasmic membrane is a vital process for all organisms. Dehalococcoides strains are strictly anaerobic organohalide respiring bacteria that lack quinones and cytochromes but express a large membrane-bound protein ...

Heavy Metal Remediation: A Sustainable Approach

Applied and Environmental Soil Science, Volume 2025, Issue 1, 2025.
With an emphasis on bioremediation as a crucial approach to mitigate the detrimental effects of heavy metals (HMs), this study explores the causes of HM pollution, their impact on the environment and human health, and remediation techniques. In contrast to traditional physical and chemical methods, bioremediation offers a more economical, less toxic ...

Proteomics of the organohalide-respiring Epsilonproteobacterium Sulfurospirillum multivorans adapted to tetrachloroethene and other energy substrates

, 2015
Organohalide respiration is an environmentally important but poorly characterized type of anaerobic respiration. We compared the global proteome of the versatile organohalide-respiring Epsilonproteobacterium Sulfurospirillum multivorans grown with ...

Ecology and biogeography of bacterial communities associated with chloroethene-contaminated aquifers

Frontiers in Microbiology, 2012
Massive usage, along with careless handling, storage, spills and leakages made chloroethenes (CEs) one of the most abundant classes of groundwater contaminants.
