Converted carotenoid production in Dunaliella salina by using cyclization inhibitors 2-methylimidazole and 3-amino-1,2,4-triazole

Carotenoid 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...

Production of a Carotenoid-Rich Product by Alginate Entrapment and Fluid-Bed Drying of Dunaliella salina

A new carotenoid-rich product was formed by entrapment of Dunaliella salina in calcium alginate beads of di†erent alginate concentrations, followed by drying in a Ñuid-bed dryer. The drying process yielded b-carotene recoveries of between 79 and 89% and produced a change in the 9-cis/all-trans ratio of b-carotene isomers. The carotenoid stability of the product was dependant on both the storage...

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...

Characterization of Dunaliella salina strains by flow cytometry: a new approach to select carotenoid hyperproducing strains

Effect 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...
