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 کاملProduction of Antioxidant by the Green Alga Dunaliella salina
The variation of the lipophilic (carotenoids and α-tocopherol) and hydrophilic (glutathione and ascorbic acid) antioxidant contents, and the activities of antioxidant enzyme such superoxide dismutase (SOD), catalase (CAT) and peroxidase (POD), as well as cellular malonaldehyde and stable radicals of D. salina in response to ultraviolet B (UV-B radiation 290-320 nm) and secondary carotenoid indu...
متن کاملCarotenoid production from microalga, Dunaliella salina
Carotenoid content of microalga, Dunaliella salina was increased using different stress parameters, such as cell division inhibition (vinblastine), nitrogen starvation, high salinity and high irradiation with high temperature. Vinblastine had very little favourable effect. Salinity above 3 M significantly decreased the cell growth rate due to cell death but increased the per cell carotenoid con...
متن کاملEffect of SiO2 Nanoparticles on Chlorophyll, Carotenoid and Growth of Green Micro-Algae Dunaliella salina
As a rapidly-evolving global technology, nanotechnology has presumably brought drastic changes to our lives in the past two decades using engineered nanoparticles, whose penetration into industrial and non-industrial wastewater requires examination of their probable effects in aquatic ecosystems. The main objective of this work is to study the toxicological and biological effects of nanomateria...
متن کاملEffect of Ca2+ Channel Block on Glycerol Metabolism in Dunaliella salina under Hypoosmotic and Hyperosmotic Stresses
The effect of Ca(2+) channel blockers on cytosolic Ca(2+) levels and the role of Ca(2+) in glycerol metabolism of Dunaliella salina under hypoosmotic or hyperosmotic stress were investigated using the confocal laser scanning microscope (CLSM). Results showed that intracellular Ca(2+) concentration increased rapidly when extracellular salinity suddenly decreased or increased, but the increase co...
