The halotolerant microalga Dunaliella salina has been widely studied for natural β-carotene production. This work shows biochemical characterization of three newly isolated Dunaliellasalina strains, DF15, DF17, and DF40, compared with D. salina CCAP 19/30 and D. salina UTEX 2538 (also known as D. bardawil). Although all three new strains have been genetically characterized as Dunaliella salina ...

 Dunaliella salina, a green microalga, has been consumed as food and medicine for a long time.The anti-oxidant and anticancer effects are related to more production of β- carotene under stress conditions compared with normal circumstances.The scope of this study was survey of anticancer effect of the ethanol extract of Dunaliella salina algae under stress(EDSS) and normal (EDSN) conditions on d...

Pressurized fluid extraction (PFE) was examined as an alternative technology for the extraction of carotenoids in the green algae Haematococcus pluvialis and Dunaliella salina and kavalactones in Piper methysticum. The extraction process was optimized by varying the key extraction factors of solvent, sample-solvent ratio, temperature, and time. The selectivity and efficiency of extraction param...

the microalgae, dunaliella salina was isolated from maharlu salt lake, south east of shiraz, iran. the isolated strain was identified by both morphological and physiological markers. the complete its region (its1 + its2) including the 5.8s rdna gene used as molecular marker confirmed our identification. growth and cell proliferation, total chlorophyll and carotenoid contents were determined in ...

Dunaliella salina is a unicellular green microalga that is considered as one of the best commercial sources of carotenoids. Growth and pigment production of D. salina (isolated from Sambhar Salt Lake, Rajasthan) was studied by using various inorganic media differing in chemical compositions viz. Artificial Sea Water media, De Walne’s media, Johnson’s media, AS-100 and Modified Bold’s Basal medi...

The mechanism of abiotic stress tolerance is crucial for plants to survive in harsh condition and the knowledge of this mechanism can be use to solve the problem of declining productivity of plants or crops around the world. However in-depth description is still unclear and it is argued, in particular that there is a relationship between high salinity tolerance and the ability to tolerate high ...

Light could induce phosphorylation of light harvesting chlorophyll a/b binding proteins (LHCII) in Dunaliella salina and spinach thylakoid membranes. We found that neither phosphorylation was affected by glycerol, whereas treatment with NaCl significantly enhanced light-induced LHCII phosphorylation in D. salina thylakoid membranes and inhibited that in spinach. Furthermore, even in the absence...

BACKGROUND Culture collapse due to high temperatures can significantly impact the profitability of outdoor algal cultivation systems. The objective of this study was to model for the first time the impact of high temperatures on algal activity and viability. RESULTS Viability measurements on Dunaliella salina cultures were based on cytometry with two fluorescent markers (erythrosine and fluor...
