Dunaliella

About

Dunaliella is a genus of single-celled, photosynthetic green algae, that is characteristic for its ability to thrive and outcompete other organisms in hypersaline environments. They are mostly marine organisms, though there are a few freshwater species that tend to be more rare. It is a genus in which certain species can accumulate relatively large amounts of β-carotenoids and glycerol in very harsh growth conditions, consisting of high light intensities, high salt concentrations, and limited oxygen and nitrogen levels, yet is still very abundant in lakes and lagoons all around the world.
