Carotene and Antioxidant Capacity of Dunaliella Salina Strains
نویسندگان
چکیده
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.

Potential of new isolates of Dunaliella salina
The halotolerant microalga Dunaliella salina has been widely studied for natural 10 β-carotene production. This work shows biochemical characterization of three newly isolated 11 Dunaliella salina strains DF15, DF17 and DF40 compared with D. salina CCAP 19/30 (confirmed to 12 be D. tertiolecta) and D. salina UTEX 2538 (also known as D. bardawil). Although all three new strains 13 have been gene...

متن کاملDNA fingerprinting differentiation between β-carotene hyperproducer strains of Dunaliella from around the world
BACKGROUND Dunaliella salina is the most important species of the genus for beta-carotene production. Several investigations have demonstrated that D. salina produces more than 10% dry weight of pigment and that the species grows in salt saturated lagoons. High plasticity in the green stage and the almost indistinguishable differences in the red phase make identification and differentiation of ...
متن کاملEffects of Salinity and Light on Growth of Dunaliella Isolates
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/m/s). The res...
متن کاملThe effect of temperature and irradiance on the growth and carotenogenic capacity of seven strains of Dunaliella salina (Chlorophyta) cultivated under laboratory conditions.
The carotenogenic microalga Dunaliella salina is cultivated as a natural source of beta-carotene. The 9-cis isomer of beta-carotene is found only in natural sources having commercial advantages over the all-trans isomer due to its high liposolubility and antioxidant power. High irradiance appears to stimulate specifically all-trans beta-carotene accumulation in D. salina, whereas low temperatur...
