Abstract

Dunaliella salina, halotorelant unicellular green algae, is the main natural source of beta-carotene. Several strains of local Dunaliella salina were isolated. Together with Dunaliella bardawil DCCBC 15 and Dunaliella salina CCAP 19/18, the strains were examined for their growth under the effects of salinities (1 M, 1.5 M and 2 M) and light intensities (50, 100 and 150 µmol photon/m²/s). The result showed optimal growth for Dunaliella was obtained at 1.5 M and 2 M salinities and 50 µmol photon /m²/s light intensity. Data of this study will be further applied for carotenogenic induction experiments using salinity and light stresses on these Dunaliella salina strains.
