Die einzellige Grünalge Dunaliella (Dunaliella salina) gilt als eines der frühesten Beispiele für Algenbiotechnologie aus den frühen Achziger Jahren. Halophilic representatives of the genus Dunaliella, notably D. salina and D. viridis, are found worldwide in salt lakes and saltern evaporation and crystallizer ponds at salt concentrations up to NaCl saturation. Cell density was determined by means of counting viable cells using a haemocytometer. Dunaliella viridis is one of the most salt-tolerant eukaryotes and a model organism to study plant adaptation to salinity. Green Algae Dunaliella viridis: Reference: Jimenez, C. and Niell, F.X. Production of dried algal meal. The best-known species of Dunaliella are Dunaliella salina, Dunaliella tertiolecta, Dunaliella primolecta, Dunaliella viridis, Dunaliella bioculata, Dunaliella acidophyla, Dunaliella parva and Dunaliella media. Authentischer Stamm., Fruehere Zuschreibungen: authentic strain ? The halophytic green alga Dunaliella viridis can use ammonium (NH4+) derived from the abiotic degradation of amino acids, and previously, supplementation of NH4+ from glutamine degradation was shown to support acceptable levels of growth and increased neutral lipid production compared to nitrate. Dunaliella is a single-celled, photosynthetic green alga, that is characteristic for its ability to outcompete other organisms and thrive in hypersaline environments. Common Names. In algae: Ecological and commercial importance. 1991. We also describe a general method for establishing and maintaining semi-continuous cultures of the halophilic microalgal production strain, Dunaliella viridis, that is independent of variations in salinity and illumination intensity. Calcium and magnesium are antagonistic. 2014. Dunaliella salina, eine grüne Meeresalge, ist in asiatischen Kulturen ein wichtiger Nahrungsbestandteil. Ten mL of algae culture was centrifuged for 10 min at 5000 g. The supernatant was discarded, and the pellet was washed once by the cell-free culture medium centrifuged. Der extrem hohe Gehalt an Betacarotin machte diese Pflanze früh für die Gesundheitsforschung interessant, ebenso wie der Fakt, dass sie in einer äußerst salinen Umgebung lebensfähig ist. To explore the molecular mechanisms mediating salt stress response in D. viridis, transcriptome analysis was performed by high- throughput sequencing. A. Kuznetsova. A whole analysis of kleptoplasty and chemical defenses in Sacoglossans may offer a better understanding of the ecology and evolution of these specialized opisthobranchs. Dunaliella viridis presented a maximum population density of 1,536.25 x 103 cell.mL-1 on the seventh day (experimental unit D40). Dunaliella viridis has also been proposed as a source of oxygenated carotenoids (Moulton and Burford 1990).
