Environmental Microbiology, Volume 27, Issue 8, August 2025.Sulphate‐reducing bacteria affiliated with clades SCA1, SCA2, and LCA2 were investigated using stable‐isotope incubations and in situ analysis at several hydrocarbon seep sites. Extrapolated rates of sulphate reduction and alkane degradation suggest that these clades play an important role at hydrocarbon seeps, contributing substantially to sulphur and

Boundaries of photosynthesis: adaptations of carbon fixation in extreme environments
FEBS Open Bio, Volume 15, Issue 7, Page 1028-1040, July 2025.Photosynthesis faces challenges from environmental extremes of temperature, pH, and salinity, limiting gas diffusion, modifying membrane fluidity, and destabilizing photochemical and biochemical reactions. Photosynthetic organisms have evolved unique adaptations overcoming these stresses and maintaining their photosynthetic activity.

Journal of Genetic Engineering and Biotechnology, 2020 Background Proteases or peptidases are an imperative class of hydrolytic enzymes capable of hydrolyzing large proteins into smaller peptides. The cold-adapted proteases show higher catalytic capacity in low temperatures as well as stability in alkaline ...

Cold-Adapted Fungi: Goldmine of Biomolecules Applicable in Industry
Applied SciencesFungi, which are widely distributed across the Earth, have successfully managed to colonize cold environments (e.g., polar regions, alpine ecosystems, and glaciers) despite the challenging conditions for life.

Computer simulations explain the anomalous temperature optimum in a cold-adapted enzyme
Nature Communications, 2020 Enzymes from organisms inhabiting cold environments (psychrophiles) have adapted to catalyzing chemical reactions at near freezing temperatures. Here – using molecular dynamics simulations – the authors analyze cold adaptation of psychrophilic α-amylase ...

Extremophiles and their application to veterinary medicine
Irish Veterinary Journal, 2004 Extremophiles are organisms that can grow and thrive in harsh conditions, e.g., extremes of temperature, pH, salinity, radiation, pressure and oxygen tension. Thermophilic, halophilic and radiation-resistant organisms are all microbes, some of which are

Psychrophiles: Ecological significance and potential industrial application
South African Journal of Science, 2018 The bulk of earth’s biosphere is cold (5 °C) that sustains a broad diversity of microbial life by triggering physiological response(s) to ensure survival in cold and frozen ecosystems.
