What is Dunaliella salina microalgae?
Dunaliella salina is a type of halophile green unicellular micro-algae especially found in hypersaline environments, such as salt lakes and salt evaporation ponds.
Is Dunaliella salina harmful?
Hence we can conclude that Dunaliella salina has been proven a safe profile up to 100 mg/kg body weight, however, it succeeded to stimulate the Hb synthesis compared to control groups, showing its benifits to be used safely as food additives or protective and curative agent in different diseases in future.
Is Dunaliella a green algae?
Dunaliella is a single-celled, photosynthetic green alga, that is characteristic for its ability to outcompete other organisms and thrive in hypersaline environments.
Where is Dunaliella found?
Dunaliella salina are found in high salinity environments such as salted brines, salt evaporation ponds, and hypersaline lakes [7]. The ability to tolerate high salt concentrations is advantageous, since competition is minimal as salt high salt concentrations.
Why is Dunaliella salina important?
Dunaliella salina and Dunaliella bardawil are the most important species for β-carotene production; however, other pigments and compounds like lutein, chlorophyll, glycerol, and polyunsaturated fatty acids are also produced by these and other Dunaliella species, making the genus one of the most important for commercial …
What does Dunaliella salina eat?
When the birds eat carotenoid-rich algae, as well as tiny crustaceans who also feed on the algae and therefore contain large concentrations of carotenoids, enzymes in the birds’ livers break down the carotenoids into pink and orange pigment molecules.
Is Dunaliella a cyanobacteria?
In ponds of intermediate (200–250 g l−1) salinity with ~3.6 μg l−1 chlorophyll a and 74–96% of the biovolume being Dunaliella (cyanobacteria being present as well at 4–9%), gross production was estimated at 0.07–1.27 μg C per μg chlorophyll a day−1 [80].
Is Dunaliella salina important to the environment?
Surprisingly, little recent information is available about Dunaliella in Great Salt Lake, where it is the main (or the only) primary producer in the north arm and an important component of the phototrophic community in the south arm. Both green D. viridis and β-carotene-rich D. salina play a role in the ecosystem.
What does Dunaliella salina look like?
Dunaliella salina (Chlorophyta) and similar hypersaline strains have biflagellated, pear-shaped cells. They lack a rigid polysaccharide cell wall, having instead a thin elastic plasma membrane. Dunaliella produces β-carotene in high amounts, up to 12% of dry matter.
How do you pronounce Dunaliella?
dunaliel·la sali·na.
What do microalgae produce?
Microalgae produce a wide range of bioproducts, including polysaccharides, lipids, pigments, proteins, vitamins, bioactive compounds, and antioxidants (Fig. 1) [3]. The interest in microalgae as a renewable and sustainable feedstock for biofuels production has inspired a new focus in biorefinery.
How do you spell Dunaliella salina?
dunaliella salina Pronunciation. dunaliel·la sali·na.
What is microalgae used for?
A range of microalgae species are produced in hatcheries and are used in a variety of ways for commercial purposes, including for human nutrition, as biofuel, in the aquaculture of other organisms, in the manufacture of pharmaceuticals and cosmetics, and as biofertiliser.
What is the importance of microalgae?
Microalgae produce a wide range of other commercially important and valuable products. They produce vitamins, which elevates their importance as a nutritional food for people and animals [136, 142]. They also produce different types of medicinally important polysaccharides.
What is Dunaliella microalga?
This microalga is a natural source of carotenoids for human use as well as for animal feed (shrimps). The high content of β-carotene makes Dunaliella attractive to biotechnologists for large-scale production in high-salinity, shallow, open ponds under high solar radiation (> 30 °C).
What is the cell shape of Dunaliella salina?
The green halophilic microalga Dunaliella salina (Chlorophyta) and similar hypersaline strains have biflagellated, pear-shaped cells. Dunaliella is the main natural source of β-carotene in high amounts, it being up to 16% of dry matter. Their cells lack a rigid cell wall, having instead a thin elastic plasma membrane.
Is Dunaliella salina biflagellated?
The green halophilic microalga Dunaliella salina (Chlorophyta) and similar hypersaline strains have biflagellated, pear-shaped cells. Dunaliella is the main natural source of β-carotene in high amounts, it being up to 16% of dry matter.
Where does Dunaliella come from?
Microalgae Culture Dunaliella sp. having 97% of similarity with D. salina, D. quartolecta and D. polymorpha was isolated from the Sebkha of Sidi El Hani (Sousse, Tunisia) [ 40 ]. It was cultivated in F/2 medium based on artificial sea water (ASW).
