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...

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 Dunal...

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 ...

Dunaliella salina is a unicellular green alga with a high α-linolenic acid (ALA) level, but a low eicosapentaenoic acid (EPA) level. In a previous analysis of the catalytic activity of delta 6 fatty acid desaturase (FADS6) from various species, FADS6 from Thalassiosira pseudonana (TpFADS6), a marine diatom, showed the highest catalytic activity for ALA. In this study, to enhance EPA production ...

Background: The genus Dunaliella (Class – Chlorophyceae) is widely studied for its tolerance to extreme habitat conditions, physiological aspects and many biotechnological applications, such as a source of carotenoids and many other bioactive compounds. Biochemical and molecular characterization is very much essential to fully explore the properties and possibilities of the new isolates of Duna...

Dinesh Kumar Culture and biofuel producing efficacy of marine microalgae Dunaliella salina and Nannochloropsis sp. J. Algal Biomass Utln. 2012, 3 (4): 38–4 Abstract Biodiesel from oil crops, waste cooking oil and animal fat cannot realistically satisfy even a small fraction of the existing...

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...

Bloom of Dunaliella salina was observed naturally in stagnant puddles of water off Kuwait's Bubiyan Island on 4 July 2004. In order to closely monitor this bloom, alga were collected and maintained as pure culture of the locally isolated D. salina. Set of experiments was conducted to study and evaluate the optimum culture conditions required for two samples of D. salina (one locally isolated an...

The plasma membrane H(+)-ATPase gene was cloned and sequenced from the extremely acidophilic green alga Dunaliella acidophila and from the extremely halotolerant Dunaliella salina. A special feature of the Dunaliella H(+)-ATPase is an extended C-terminal domain. The deduced amino acid sequences of the two proteins are 75% identical but differ in their C terminus. A hydrophilic loop within this ...
