Antioxidant Production in Dunaliella [PDF]
Applied Sciences (Switzerland), 2021 Microalgae have become an attractive natural source of a diverse range of biomolecules, including enzymatic and non-enzymatic antioxidants; nevertheless, economically sustainable production of such compounds from microalgae biomass is still challenging. The main hurdles are: (a) increasing microalgae yield; (b) achieving optimal cultivation conditions;

Physiological responses of Dunaliella salina and Dunaliella tertiolecta to copper toxicity
Biomolecular Engineering, 2005Species differences in heavy metal tolerance were investigated by comparing the responses of Dunaliella tertiolecta and Dunaliella salina to elevated concentrations of CuCl2. Although both species showed reduced cell number ml(-1) of algal culture, D. salina was more affected by increase in CuCl2. This reflects higher sensitivity of D.

Dunaliella salina Hsp90 is halotolerant
International Journal of Biological Macromolecules, 2015Dunaliella salina is a unicellular green alga with exceptional halotolerance. Although the D. salina cells are capable to proliferate in hypersaline medium, the intracellular salt concentrations are maintained at a low level. Thus the extracellular but not intracellular Dunaliella proteins are expected to be highly halotolerant.

Sterols have been extracted and analysed from Dunaliellatertiolecta and Dunaliella salina, in order to evaluate a potentially novel industrial exploitation of these microalgae as source of phytosterols. The effect of salt concentration on sterols yields has been studied varying the quantities of NaCl into culture medium.

The development of nanotechnology and the upsurge of interest in titanium dioxide (TiO2) nanoparticles, especially the anatase and rutile crystalline phases, in consumer products such as paint and sunscreen, has polluted the aquatic environment and had adverse effects on living organisms, especially algae.

Lipid composition of halotolerant algae, Dunaliella parva lerche and Dunaliella tertiolecta
Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1982Abstract The lipids of two halotolerant algae, Dunaliella parva Lerche and Dunaliella tertiolecta , contained predominantly the glycolipids monogalactosyldiacylglycerol (21.4 and 22.2 mol% for D. parva and D. tertiolecta , respectively), digalactosyldiacylglycerol (11.4 and 20.5 mol%), sulfoquinovosyldiacylglycerol (6.5 and 9.5 mol%) and two ...

Carotenoids are essential natural pigments, and ZISO plays a pivotal role in their biosynthesis. This study compares ZISO enzyme activity in Dunaliella salina and Dunaliella bardawil to evaluate their efficiency in synthesizing 9,9'-di-cis-ζ-carotene. Bacterial strains lacking ZISO (ΔDsZISO, ΔDbZISO) and ZDS (ΔDsZDS, ΔDbZDS) were constructed, and HPLC ...
