Permafrost as a source of mineral weathering bacteria: Implications of active layer thickening on James Ross Island, Antarctica

Micenková et al., CATENA 2025
Microbiological research in Antarctica provides a unique perspective on biodiversity and the influence of geochemistry on soil microbial composition. Samples from a 350 cm deep core were analyzed in the area of the J. G. Mendel Czech Antarctic Station on James Ross Island. Geological transitions, such as the interface between the active layer and permafrost or the change between Holocene marine sediments and Cretaceous rocks, had a key influence on microbial composition. Due to warming, the interaction between microbial communities in the active layer and permafrost is expected to deepen in the future.

Effect of soil depth on the structure of bacterial composition in the active layer at five geologically distinct sites on James Ross and Vega Islands in Antarctica

Micenková et al., Polar Biology 2024
We have published what microbes we find in the surface layer above permafrost, known as the active layer, which thaws seasonally and is considered an important component of terrestrial ecosystems, where these microbes represent significant source of new bacterial species with potential, e.g., as a promising source of new antimicrobial compounds.
