Carotenoids are a group of pigments which have an important role in plants light absorbance. They include mainly Beta-carotene, alpha-carotene, lycopene and xanthophyll. Beta-carotene is industrially produced in a few countries due to its widespread use such as; food pigments, cosmetics and precursor of vitamin A. In this study, high light intensity has been applied to microalgae species that obtained from Caspian Sea and pure culture of Dunaliella Salina. The accumulated Beta-carotene in Caspian Sea microalgae was comparable to the obtained values of pure microalgae of Dunaliella Salina. Therefore, mixed microalgae culture can be used for Beta-carotene production which is preferable and more economical than sterile systems and consequently the possibility of process industrialization will be increased.
