Production 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 کاملCarotene and Antioxidant Capacity of Dunaliella Salina Strains
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...
متن کاملPotential 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 کاملHepatoprotective and Antioxidant Activity of Dunaliella salina in Paracetamol-induced Acute Toxicity in Rats
Paracetamol has a reasonable safety profile when taken in therapeutic doses. However, it could induce hepatotoxicity and even more severe fatal acute hepatic damage when taken in an overdose. The green alga, Dunaliella salina was investigated for hepatoprotective and antioxidant activity against paracetamol-induced liver damage in rats. Male albino Wistar rats overdosed with paracetamol showed ...
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...
