Description

Application

• Molecular mechanisms of carotenoids in locusts: Research detailed the molecular interactions between carotenoids and chitin-binding proteins in locusts, illuminating β-carotene′s role in natural coloration processes, which can be applied to biochemistry and genetics studies (Egorkin et al., 2024).


• Carotenoids in Corynebacterium glutamicum: A study demonstrated the enhanced biosynthesis of astaxanthin and the potential for glycosylated C40 carotenoids production in Corynebacterium glutamicum, suggesting applications in cell culture experiments where β-carotene′s antioxidant properties are investigated (Göttl et al., 2024).
