Habitat
Few organisms can survive as D. salina does in such highly-saline conditions as
It has been thought for a long time that the colour of pink lakes was the result of this alga, as it has been found in many pink lakes and contains substances in a range of hues that include pink.[2] However, research done in Australia since 2015 in Lake Hillier found several species of halophilic bacteria and archaea as well as several species of Dunaliella, nearly all of which contain some pink, red or salmon-coloured pigment.[3][4][5][2]

Due to the abundance of
Glycerol
Attempts have been made to exploit the high concentrations of glycerol accumulated by D. salina as the basis for the commercial production of this compound. Although technically the production of glycerol from D. salina was shown to be possible, economic feasibility is low and no biotechnological operation exists to exploit the alga for glycerol production.[8]
