Dunaliella salina - Overview
Dunaliella salina Dunaliella salina is a unicellular microalgae belong to division Chlorophyta . It is found in salinity environments such as salted brines, salt evaporation ponds, and hypersaline lakes .It is able to tolerate varying NaCl concentrations, ranging from 0.2% to approximately 35% . Thus, Dunaliella salina is a hyper-halotolerant organism found in high densities in saline lakes. The ability to tolerate high salt concentrations is advantageous, since competition is minimal in high salt concentration areas. How D.salina tolerate high salt concentration? D. salina has adapted to survive in high salinity environments by accumulating glycerol to balance osmotic pressure. Note : D. salina is also adapted to solar radiation using β-carotene to protect against ionizing energy. Red Colour of Salt Brines Dunaliella salina...
