Cold-adapted microorganisms possess cold-active enzymes with potential applications in different industries and research areas. In this study, two genes encoding β-d-galactosidases belonging to Glycoside Hydrolase families 2 and 42 from the psychrotolerant Arctic bacterium sp. S3* were cloned, expressed in and , purified and characterized.

- The unconventional yeast species is a rich source of protein and nutrients, particularly kynurenic acid (KYNA), which may positively influence metabolism as shown in a nutritional experiment with mice.
- The study compared high-KYNA and low-KYNA yeast by analyzing KYNA content, amino acid composition, and antioxidant indicators using high-performance liquid chromatography.
- Results indicated that while high-KYNA yeast had a greater KYNA concentration, it had lower crude protein and less favorable amino acid composition, but did not significantly impact body weight or food intake in mice, though some trends in blood parameters were observed.
