Cold and hot extremozymes: industrial relevance and current trends
Frontiers in Bioengineering and Biotechnology, 2015 The development of enzymes for industrial applications relies heavily on the use of microorganisms. The intrinsic properties of microbial enzymes e.g. consistency, reproducibility and high yields along with many others, has pushed their introduction into

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 ...

Biotechnological uses of enzymes from psychrophiles [PDF]
, 2011 The bulk of the Earth's biosphere is cold (e.g. 90% of the ocean's waters are ≤ 5°C), sustaining a broad diversity of microbial life. The permanently cold environments vary from the deep ocean to alpine reaches and to polar regions. Commensurate with the

Understanding High-Salt and Cold Adaptation of a Polyextremophilic Enzyme
Microorganisms, 2020 The haloarchaeon Halorubrum lacusprofundi is among the few polyextremophilic organisms capable of surviving in one of the most extreme aquatic environments on Earth, the Deep Lake of Antarctica (−18 °C to +11.5 °C and 21–28%, w/v salt content). Hence, H.

Some Like It Hot –Structural Changes in Extremophile Rubredoxin at 120 °C
Angewandte Chemie, Volume 138, Issue 5, 28 January 2026.We reveal the high temperature crystal structure of a hyperthermophilic (Pyrococcus furiosus) rubredoxin at 393 K (120 °C), together with multiple complementary structures down to 100 K. The results are compared with molecular dynamics calculations. Significant changes in H‐bonding are observed.

Capsular polysaccharides and lipopolysaccharides from psychrophiles: structural characterization and biological activity. [PDF]
, 2022 Psychrophiles are microorganisms able to colonize cold environments. Some of the adaptation strategies of Gram-negative bacteria involve the external layer (such as LPSs and CPSs).

Disappearing Kilimanjaro snow—Are we the last generation to explore equatorial glacier biodiversity?
Ecology and Evolution, 2019 Glaciation accompanied our human ancestors in Africa throughout the Pleistocene. Regrettably, equatorial glaciers and snow are disappearing rapidly, and we are likely the last generation who will get to know these peculiar places. Despite the permanently

Metagenomic Analysis of Low-Temperature Environments [PDF]
, 2017 The Earth’s permanently cold biosphere is known to harbour abundant microbial biomass and represents a rich resource for the discovery of novel cold-adapted microorganisms, many of which form part of the ‘microbial dark matter’ which cannot be analysed ...
