Abstract

Beta-carotene is a terpenoid pigment that is highly valuable due to its nutritional benefit as a precursor of vitamin A and its antioxidant properties. A marine green alga Dunaliella salina is well known for high carotene, with above 95% β-carotene, under growth-limiting conditions. Carotene contents are different among D. salina strains and under different culture conditions. Selecting a Dunaliella salina strain with high carotene amount for mass cultivation is crucial. Hence, this study aimed to select a candidate Dunaliella salina for carotene production. Analysis of total carotene contents and antioxidant capacities from 8 different local isolated D. salina strains (A9, A10, A11, A12, A13, D, E and G) and 2 imported strains (D. salina CCAP 19/18 and D. bardawil DCCBC 15) revealed that D. bardawil DCCBC 15 excelled than other strains basing on total carotene and antioxidant capacity per cell and per volume of culture.
