Microalgae are one of the safest sources of protein production in the world that have good sources of a wide range of beneficial compounds, including proteins, fats and pigments. This research aims to use the cultivation of Dunaliella salina in Modified Johansson (DUM) and Guillard (f/2) media under salinity stress of 10, 20, 30%, culture media efficiency and the effect of salinity stress on Chlorophylls a and b as well as total carotenoids should be investigated. The results showed that the highest production of Chlorophylls a and b are 8.20±0.008 and 3.85±0.06 μg/mg, respectively, which is produced by the sample grown with DUM medium at 10% salinity. Also, the highest amount of carotenoids was 1.79±0.30 μg/mg which was produced by the sample grown in culture medium f/2 with a salinity concentration of 30% under stress. The highest cell growth was 7808333±52041/6 cells/ml at 10% salinity in Gillard culture medium. The results of this study showed that Dunaliella salina algae is a good source of carotenoids when exposed to salinity stress.
