Detection of Microorganisms in Low-Temperature Water Environments by in situ Generation of Biogenic Nanoparticles

Frontiers in Astronomy and Space Sciences, 2020
A new nanobiotechnological approach for the detection of extraterrestrial Earth-like biological forms is proposed. The approach is based on the ability of microbial cells to reduce artificially added cations with the generation of crystalline ...

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 ...

Preservation Strategies for Camel Meat: Quality Improvement and Shelf‐Life Extension

Food Science &Nutrition, Volume 14, Issue 4, April 2026.
Camel meat, a crucial protein source in arid regions, faces challenges like high moisture content and susceptibility to spoilage, limiting its shelf life. Traditional methods such as salting, drying, and smoking have been used historically, while modern techniques like refrigeration, freezing, and vacuum packaging enhance quality and safety.

Adaptation, production, and biotechnological potential of cold-adapted proteases from psychrophiles and psychrotrophs: recent overview

, 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 ...
