Microbial community composition of transiently wetted Antarctic Dry Valley soils [PDF]

, 2015
During the summer months, wet (hyporheic) soils associated with ephemeral streams and lake edges in the Antarctic Dry Valleys (DVs) become hotspots of biological activity and are hypothesized to be an important source of carbon and nitrogen for arid DV ...

Isolation and Characterization of Cold-Tolerant Hyper-ACC-Degrading Bacteria from the Rhizosphere, Endosphere, and Phyllosphere of Antarctic Vascular Plants

Microorganisms, 2020
1-Aminociclopropane-1-carboxylate (ACC)-degrading bacteria having been widely studied for their use in alleviating abiotic stresses in plants. In the present study, we isolated and characterized ACC-degrading bacteria from the rhizosphere, phyllosphere ...

Potential for resistance to freezing by non-virulent bacteria isolated from Antarctica

Anais da Academia Brasileira de Ciências, 2022
Industrial sectors are searching for new compounds to improve the preservation of food and blood, human tissues, and fuels used at low temperatures. Antarctic microorganisms have mechanisms to overcome injuries caused by low temperatures, making them ...

Seed Storage Conditions for Zostera muelleri Restoration: Effects of Temperature, Salinity and Sterilisation on Seed Contamination, Viability and Seedling Emergence

New Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 4, December 2026.
The decline of seagrass meadows is a continuing global concern, and seed‐based restoration provides a scalable approach to recovering lost and degraded meadows. Such approaches require large quantities of seed to be collected, processed, and often stored for months until deployment.

Single‐Cell Identification of Bacterivorous Mixotrophs in a Freshwater Habitat

Environmental Microbiology Reports, Volume 18, Issue 6, December 2026.
A workflow diagram showing the taxonomic identification of bacteria‐consuming mixotrophs from natural environments, achieved through fluorescence‐activated single‐cell sorting and microscopic observation. The single‐cell approach allows us to establish a clear connection between biodiversity and functional activities in aquatic environments with high ...

Spatial Variation of Bacterial Communities Associated With the Moss Sanionia uncinata on Deception Island, Antarctica

Environmental Microbiology Reports, Volume 18, Issue 6, December 2026.
Bacterial communities associated with the Antarctic moss Sanionia uncinata differed in composition among three sampling locations on Deception Island, whereas alpha diversity and predicted functional profiles were similar. These results suggest that this moss harbours spatially structured bacterial communities with potential functional redundancy ...

Effects of hydrocarbon spills on the temperature and moisture regimes of Cryosols in the Ross Sea region [PDF]

, 2002
Hydrocarbon spills have occurred on Antarctic soils where fuel oils are utilized, moved or stored. We investigated the effects of hydrocarbon spills on soil temperature and moisture regimes by comparing the properties of existing oil contaminated sites ...
