Abstract

Microalgae Dunaliella salina, known as the most important source of beta-carotene production in nature, is a eukaryotic microorganism that has a high tolerance range for fluctuations in environmental conditions such as salinity (0.5-5 M), temperature (20-40 C°) and light (50 to 1500 μmol m-2 s-1). This alga has shown antioxidant, anti-cancer and antimicrobial activity due to their beneficial compounds such as carotenoid pigment, glycerol and unsaturated fatty acids, and are therefore a good candidate for use in the food, pharmaceutical and cosmetic industries. Various companies around the world have become interested in its commercial production and have designed and used several systems for its mass cultivation, including cultivation in outdoor ponds or indoor photo bioreactors. Despite the many biological benefits of this microalgae and the efforts to mass-production of this microalgae, there are still barriers to its commercial and cost-effective production. These challenge are mostly related to downstream production processes including harvesting, drying and oil and commercial pigments extraction.
