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.

Microbiome dynamics of a polychlorobiphenyl (PCB) historically contaminated marine sediment under conditions promoting reductive dechlorination

Frontiers in Microbiology, 2016
The toxicity of polychlorinated biphenyls (PCB) can be efficiently reduced in contaminated marine sediments through the reductive dechlorination process lead by anaerobic organohalide bacteria.

Metagenomic- and Cultivation-Based Exploration of Anaerobic Chloroform Biotransformation in Hypersaline Sediments as Natural Source of Chloromethanes

Microorganisms, 2020
Chloroform (CF) is an environmental contaminant that can be naturally formed in various environments ranging from forest soils to salt lakes. Here we investigated CF removal potential in sediments obtained from hypersaline lakes in Western Australia ...

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 ...

Bibliometrics and Visualization Analysis of Three Obligate Organohalide Respiring Bacteria Genera: A Systematic Review

Microorganisms
Organohalide-respiring bacteria (OHRB) facilitate the reductive dehalogenation of toxic halogenated compounds in the environment, which supports their growth and proliferation. Research conducted on OHRB has achieved notable advancements.

Functional Expression and Characterization of Tetrachloroethene Dehalogenase From Geobacter sp.

Frontiers in Microbiology, 2018
Reductive dehalogenase (RDase) consists of two parts, RdhA and RdhB. RdhA is the catalytic subunit, harboring a cobalamin cofactor and two Fe–S clusters. RdhA is anchored to the cytoplasmic membrane via the membrane anchoring subunit, RdhB.

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 ...
