Effects of salt stress on total lipid values, fatty acid profiles, omega-3, omega-6 and omega-9, in the brown algea Sargassum boveanum on Bushehr coast
Some algae are rich sources of various beneficial lipids and fatty acids. In recent years, several studies have been performed on algae to evaluate the effect of different salinity treatments on the quantity and quality of these lipids. The present study was performed to investigate the effect of different concentrations of sodium chloride on total lipid content, fatty acid profile, and omega-3...
متن کاملModeling Growth of Microalgae Dunaliella Salina under Different Nutritional Conditions
Problem statement: The aim of this study was to find the empirical model that describes the growth kinetics of Dunaliella salina, with low production cost and to estimate parameters of this model. Approach: In this study the strain of D. salina UTEX 200 was cultivated in seawater (0.5 M NaCl) at room temperature with agitation of 150 rpm and luminous intensity of 60 mmols.m-2.s-1. The synthetic...
متن کاملSalt induction of fatty acid elongase and membrane lipid modifications in the extreme halotolerant alga Dunaliella salina.
In studies of the outstanding salt tolerance of the unicellular green alga Dunaliella salina, we isolated a cDNA for a salt-inducible mRNA encoding a protein homologous to plant beta-ketoacyl-coenzyme A (CoA) synthases (Kcs). These microsomal enzymes catalyze the condensation of malonyl-CoA with acyl-CoA, the first and rate-limiting step in fatty acid elongation. Kcs activity, localized to a D....
متن کاملEFFECTS OF SALT AND IRRADIANCE STRESS ON PHOTOSYNTHETIC PIGMENTS AND PROTEINS IN DUNALIELLA SALINA TEODORESCO
The aim of this study was to examine the effects of salinity and light intensity on the chlorophylls, ?-carotene and protein contents in Dunaliella salina Teod. The algae were grown in inorganic medium containing 0, 0.9, 1.8 (control), 2.6 and 3.5 M NaCl under three illumination regimens [4500 (control), 9000 and 11000 Lux]. The results showed that most electrophoresis protein bands were separa...
متن کاملFatty Acid Acylated Proteins of the Halotolerant Alga Dunaliella salina.
The unicellular, wall-less alga Dunaliella salina has been shown to contain an array of proteins modified by the covalent attachment of fatty acids. Myristic acid (14:0) comprised approximately 80% by weight of the protein-linked acyl groups in samples derived from cells cultured in medium containing 1.7 molar NaCl and 93% in samples from cells grown in medium containing 3.0 molar NaCl. Palmiti...
