A periodic CO2 dosing strategy for D. salina 19/30 batch culture is proposed. A model of periodic CO2 dosing including dosing time calculation, dosing interval estimation and final chlorophyll yield prediction was established. In experiments, 5% CO2/95% N2 gas was periodically dosed into D. salina culture. Two different gas dosing flow rates were tested. The corresponding dosing time for each f...

In the present work, the antimicrobial activity of different pressurized liquid extracts obtained from Dunaliella salina microalga was tested against several microorganisms of importance for the food industry (Escherichia coli, Staphylococcus aureus, Candida albicans, and Aspergillus niger). Different solvents (hexane, petroleum ether, hexane, and water) and extraction conditions (40, 100, and ...

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...

Dunaliella salina is a halotolerant, photoautotrophic marine microalga and one of the richest sources natural carotenoids but also shows potential as novel food source with high protein quality. This study sought to optimise production biomass, amino acids from D. salina, alongside using two-stage cultivation approach based on use light different intensities quality, i.e., white, red blue LED l...

the individual effects of cadmium concentrations (0, 0.005, 0.05and 0.5 mg. l-1) on the growth(cell number and chlorophyll content) and beta-carotene synthesis of two strains (iranian and australian) ofgreen algae d.salina have been studied for a duration of 36 days. the effects of these cadmiumconcentrations on the amount of cell magnesium and calcium have also been evaluated. an increase inca...
