Laboratory cultures and mixed-species microcosms were used to asses the growth and characterization of Dunaliella sp. from Jepara Coastal Region with special emphasis on the several factors that affecting growth of organisms including salinity. The result showed that Dunaliella sp. could adapted to a variety of salt concentration from as low as 0.0 % to salt saturation of about 30 ‰.
