Extremophile enzyme activity lab: using catalase from Pyrobaculum calidifontis to highlight temperature sensitivity and thermostable enzyme activity

Journal of Microbiology & Biology Education
There are places on earth that are considered to possess extreme physico-chemical characteristics as they relate to life. Surprisingly, there are microbes that have adapted various strategies that enable them to form robust communities in these ...

Structure and function of the Ts2631 endolysin of Thermus scotoductus phage vB_Tsc2631 with unique N-terminal extension used for peptidoglycan binding

Scientific Reports, 2019
To escape from hosts after completing their life cycle, bacteriophages often use endolysins, which degrade bacterial peptidoglycan. While mesophilic phages have been extensively studied, their thermophilic counterparts are not well characterized.

Exploration of Alkaliphilic Bacteria Alkalitalea saponilacus Identifies Glycoside Hydrolases With Biotechnological Potential

Microbial Biotechnology, Volume 19, Issue 9, September 2026.
Soda lakes represent an excellent resource in the search for microbes adapted to alkaline and hypersaline conditions. In this study we demonstrate the ability of Alkalitalea saponilacus to degrade multiple carbon sources representing a promising bacterium for biotechnological applications where performance under alkaline or strongly ionic conditions is

FROM POLAR REGIONS TO VOLCANIC AND HYPERSALINE AREA : BIOSYNTHESIS, CHEMISTRY AND APPLICATIONS OF EXOPOLYSACCHARIDES BY EXTREMOPHILES

, 2018
Extremophiles have developed various adaptations, enabling them to compensate for the deleterious effects of extreme conditions as high temperatures, salt presence, low pH values, or high radiation levels. Among the adaptive strategies, exopolysaccharide

Hsp70 diversification and repurposing across the tree of life: Lessons from the evolutionary and mechanistic trajectory of the Hsp70–Hsp110 chaperone system

The FEBS Journal, Volume 293, Issue 18, Page 5541-5557, September 2026.
Evolutionary and mechanistic divergence in the Hsp70–Hsp110 chaperone system. Prokaryotic Hsp70s probably diversified into multiple orthologues that cooperated with co‐chaperones such as JDPs and NEF, forming increasingly complex proteostasis networks.

Extremophiles: A New Way of Life in Extreme Environments?

, 2023
Extremophiles are an important resource for astrobiologists, and this paper looks at some of the major scientific questions that surround the search for extraterrestrial life in the Solar System (and beyond).

Cross‐Species Plasticity and Divergence Under Alkaline Soil Signature Conditions Differentiating PYE From FIT Target Transcripts in the Arabidopsis thaliana Ferrome

Plant, Cell &Environment, Volume 49, Issue 9, Page 6719-6736, September 2026.
ABSTRACT Soil pH is an influential abiotic environmental factor. Here, we identify responses to central stimuli associated with calcareous alkaline soils in Arabidopsis and comparatively explore the potential of the closely related Arabidopsis halleri for addressing how plants cope with local soil pH.

Dimethyl sulfoxide reduction by a hyperhermophilic archaeon Thermococcus onnurineus NA1 via a cysteine-cystine redox shuttle

, 2016
To date, a variety of microbes are known to grow by respiration with dimethyl sulfoxide (DMSO) as an electron acceptor, and several distinct DMSO respiratory systems, consisting of electron carriers and a terminal DMSO reductase, have been characterized,

Impact of Salinity Duration on Growth, Photosynthesis, Water Relations, and Recovery Capacity Reveals Adaptive Responses in Hordeum maritimum

Physiologia Plantarum, Volume 178, Issue 5, September/October 2026.
ABSTRACT Although the physiological mechanisms underlying salt tolerance in wild barley (Hordeum maritimum) are relatively well understood, its recovery after salt stress remains poorly characterized. In this pot experiment, plants were exposed to 200 mM NaCl for 0, 15, 30, 45, or 60 days to evaluate changes in growth and water status.
