A new method to measure intracellular volume in Dunaliella was developed, where lithium ions are used as monitors of the extracellular volume. Li(+) is shown to be impenetrable to the intracellular volume, insignificantly absorbed to the algae, and is rapidly and evenly distributed within the extracellular volume. The method is suggested to be free of several limitations and consistent errors p...

The locally isolated harpacticoid copepods Tigriopus sp. and Tisbe holothuriae were subjected to salinity tolerance experimentation at salinities under above of 40 ppt, presented high halotolerances in LC50 (24 h) 1 ± 4.43 ppt 132 5.35 respectively, 15 2.41 93 3.23 respectively. Tetraselmis suecica, among other microalgal feeds (Asteromonas gracilis, Rhodomonas salina, Dunaliella salina Isochry...

Eukaryotic marine microalgae like Dunaliella spp. have great potential as a feedstock for liquid transportation fuels because they grow fast and can accumulate high levels of triacylgycerides with little need for fresh water or land. Their growth rates vary between species and are dependent on environmental conditions. The cell cycle, starch and triacylglycerol accumulation are controlled by th...

Microalgae represent a promising solution in addressing the impacts associated with current agricultural and manufacturing practices which are causing irreparable environmental damage. have considerable biosynthetic potential, being rich source of lipids, proteins, high-value compounds. Under scope H2020-BBI MULTI-STR3AM project, an innovative large-scale production system valuable commodities ...

BACKGROUND Dunaliella salina is the most important species of the genus for beta-carotene production. Several investigations have demonstrated that D. salina produces more than 10% dry weight of pigment and that the species grows in salt saturated lagoons. High plasticity in the green stage and the almost indistinguishable differences in the red phase make identification and differentiation of ...

Beta-carotene is a valuable carotenoid in high demand as a natural food coloring agent, provitamin A, additive to cosmetics, and health food. It can be accumulated up to more than 10% of cellular dry weight of Dunaliella salina under carotenogenic conditions such as high irradiance, high temperature, high salt concentration and nutrient deficiency. High beta-carotene productivity in Dunaliella ...

Highlight Research The growth rate was higher when Chlorella induced by Azospirillum brasilense. carbohydrate content increased combined with Determination of astaxanthin accumulation in Haematococcus pluvialis. Define condition favoring Abstract Dunaliella sp. is a potential natural source carotenoid pigments such as astaxanthin, β-carotene, and lutein. can also accumulate other valuable produ...
