Atmospheric Microbial Transport to Antarctica and Its Ecological Implications: A Systematic Review

Environmental Microbiology, Volume 28, Issue 9, September 2026.
Atmospheric transport to Antarctica operates via long‐range advection, marine aerosolization, and local resuspension, acting as a strict ecological filter. This selective barrier could actively shape local ecosystems by seeding them with functionally distinct, stress‐adapted microbial pioneers capable of surviving extreme conditions.

Surviving in hot and cold: psychrophiles and thermophiles from Deception Island volcano, Antarctica [PDF]

, 2018
Polar volcanoes harbor unique conditions of extreme temperature gradients capable of selecting different types of extremophiles. Deception Island is a marine stratovolcano located at Maritime Antarctica that is notable for its pronounced temperature ...

Effect of Seaweed Fucoidan Incorporated Into Batter on Shelf Life Extension of Silver Carp (Hypophthalmichthys molitrix) Nugget During Refrigerated Storage

Food Science &Nutrition, Volume 14, Issue 7, July 2026.
The fucoidan from Sargassum angustifolium incorporated directly in batter (0%, 1%, 2%, and 3% w/w; C, F1, F2, and F3, respectively) of silver carp (Hypophthalmichthys molitrix) nuggets increased some physiochemical properties during the refrigerated storage.

Characterisation of a cold‐adapted, thermostable glucokinase from psychrophilic Pseudoalteromonas sp. AS‐131 reveals how the enzyme achieves high thermal stability without loss of cold adaptation

The FEBS Journal, Volume 293, Issue 9, Page 2617-2636, May 2026.
We investigated glucokinase from the psychrophilic Pseudoalteromonas sp. AS‐131 (PsGK), which was isolated from the Antarctic Ocean. Biochemical studies revealed that PsGK is a cold‐adapted enzyme with high thermal stability, in contrast to general cold‐adapted enzymes, which have low thermal stability.

Biomedical Applications of Nanozymes: An Enzymology Perspective

Angewandte Chemie, Volume 137, Issue 46, November 10, 2025.
With a lens of enzymology, this review compares nanozymes with enzymes using the Michaelis‐Menten model and differences in KM and kcat along with catalysis in complex biological environment. The implications of these differences in biomedical applications of nanozymes are then described with a statistical analysis of the trend of therapeutic use of ...

Ropiness is milk… Psychrophilic bacteria and California milk quality

California Agriculture, 1962
Although California's milk supplies, with rare exception, are easily kept well within California Agricultural Code specifications, a few dairy plants have occasionally encountered ropiness in pasteurized milk. This ropiness and some other storage defects

Microbial Metabolism in Soil at Subzero Temperatures: Adaptation Mechanisms Revealed by Position-Specific 13C Labeling

Frontiers in Microbiology, 2017
Although biogeochemical models designed to simulate carbon (C) and nitrogen (N) dynamics in high-latitude ecosystems incorporate extracellular parameters, molecular and biochemical adaptations of microorganisms to freezing remain unclear.

Application of Cheese Whey Containing Postbiotics of Lactobacillus acidophilus LA5 and Bifidobacterium animalis BB12 as a Preserving Liquid in High-Moisture Mozzarella

Foods, 2022
High-moisture mozzarella cheese (HMMC) is a highly perishable cheese with a short shelf life. In this study, the effects of UF cheese whey containing postbiotics from Lactobacillus acidophilus LA-5 (P-LA-5), Bifidobacterium animalis BB-12 (P-BB-12), and ...
