Outdoor cultivation of Dunaliella salina KU 11 using brine and saline lake water with raceway ponds in northeastern Thailand Zhe Wu. In addition, cultivations in wastewaters may encounter some nutrient limitations. North latitude 39, the most appropriate place for the growth of spirulina. In this study, bicarbonate was proposed as an alternative carbon source to overcome exceedingly low CO 2 fixation efficiency of conventional microalgae cultivation system. D. salina was grown in different media obtained by replacing standard Guillard medium (F/2) with SW at 0% (control), 10%, 25%, 50%, 75%, and 100% ratios. Seagrass has developed a proprietary technology to cultivate three major marine algae, especially Dunaliella salina (DS) micro-algae. Four blades paddle wheel for culture mixing was driven to create 0.15 m/sec flow speed. La microalga Dunaliella salina es una especie que vive en aguas muy salinas, y que acumula una gran cantidad de betacaroteno, lo que la convierte en una especie muy interesantes con grandes beneficios tanto en cosmética como en alimentación Esta semana nos gustaría contaros un poco sobre un tema que sabemos que os interesa, Mon installation pour la culture de l'algue Dunaliella Salina et l'élevage d'artemias - Duration: 5:02. 13 Mice with breast tumors also benefited from Dunaliella treatment; they had significantly fewer tumors than mice who were not given Dunaliella. K. kirti s New Member. Dunaliella Batch culture Two-phase growth mode Productivity Carotenoids Abstract Productional and biochemical characteristics of green alga Dunaliella salina (Dunal) Teodoresco were studied during pilot cultivation at the south-west of Crimean Peninsula, Russia. Tianjin Key Laboratory of Marine Resources and Chemistry, Tianjin University of Science and Technology, Tianjin, 300457, P.R. If yes, please leave your contact#. Oct 1, 2013 #2 hello Sir Beta-Carotene is extracted from a potent natural source of Dunaliella salina sea algae. 12 Mice with cancer in the upper digestive tract were given high doses of Dunaliella extract; their cancer was inhibited by 55%. Dunaliella salina was used as a model organism in this study. Dunaliella salina is a type of halophile green micro algae especially found in sea salt fields. Dunaliella-based algae biorefinery concepts Del 7.5 1 Executive Summary The EU funded project D-Factory "The micro algae biorefinery" seeks to demonstrate a sustainable CO 2 algae biorefinery based on the cultivation and processing of the alga Dunaliella salina for natural prod-ucts and potentially multiple markets. One of the challenges in commercial‐scale cultivation of Dunaliella salina is low biomass productivity and concentration. The cell d … In this study, the laboratory-scale cultivation of Dunaliella salina was performed to explore the cost and biochemical effects on biomass cultivated using F/2, Conway, and Johnson media. Results showed that the optimum inoculum concen-tration was OD 630 = 0.15 and the optimum circulation rate of culture Xuid was 630 mL/h for the bioreactor.

Known for its anti-oxidant activity because of its ability to create large amount of carotenoids, it is used in cosmetics and dietary supplements. Enhancement of co-production of nutritional protein and carotenoids in Dunaliella salina using a two-phase cultivation assisted by nitrogen level and light intensity. But don’t let its pedigree fool you--this little alga is bright pink! Dunaliella salina Teodoresco is a green microalga recognized at present as the most salt-tolerant eukaryote known. The microalga Dunaliella salina was studied at the main stages of transition from laboratory to pilot-scale cultivation: strain selection, nutrient medium selection, estimation of influence of physicochemical factors on accumulation of carotenoids and evaluation of the selected strain growing technology at pilot conditions. cultivation methods, control of primary and secondary metabolism, strain selection and selective extraction methods possible. 2, Wang S. 2 . The pond volume was 1,500 1 at 20 cm depth. The alga Dunaliella salina was chosen because it grows well in highly saline non-potable water across the globe, using CO 2 and solar energy. Under growth-limiting conditions, some strains of D. salina can accumulate more than 10% of their dry weight in β-carotene (Ben-Amotz et al., 1982; Ben-Amotz & Avron, 1983b; Borowitzka & Borowitzka, 1988), giving rise to the richest natural source of this pigment known so far. There is still a growing demand for the best strain identification and growth conditions optimization for maximum carotenoids production. Interdisciplinary Graduate Program in Bioscience, Faculty of Science, Kasetsart University, Thailand. Dunaliella responds to transfer to a high salinity by enhancement of photosynthetic CO 2 assimilation (Oren 2005). An important cultivation parameter is light wavelength (λ).
