Diversity of carotenogenic microalgae in the White Sea polar region
Abstract Carotenogenic microalgae are unicellular photosynthetic organisms with the ability to accumulate carotenoids. Carotenoid accumulation is a protective reaction against environmental stress factors, such as bright light, extreme temperatures, etc. It makes the survival of these microorganisms...
