dunaliella salina harmful effects

M Boonyaratpalin. In this study, Astronotus ocellatus were fed with food supplemented with Dunaliella salina (a natural β-carotene source) or astaxanthin (synthetic pigment), and their effects on fish skin carotenoids, growth indices and immune responses were evaluated. Dunaliella salina algae is bombarded with the full brunt of solar UV (ultraviolet) radiation and has evolved a novel mechanism for defending itself from the radiation’s damaging effects. Dunaliella salina is a type of halophile green micro-algae especially found in sea salt fields. Survival stage. ABSTRACT: A study was conducted to investigate the effect of different pH, on the growth and biopigment accumulation of a green alga Dunaliella salina isolates from Sambhar salt lake, Rajasthan (India). Anticancer effect of Dunaliella salina under stress and normal conditions against skin carcinoma cell line A431 in vitro Emtyazjoo Mo 1; Moghadasi Z. These cultures were neither axenic nor unialgal and contained mainly D. salina as well as low numbers of D. viridis. More than 8% of its dry body mass is β-carotene, more than any other organism that produces the compound. 135 A. ocellatus, weighing 25.6 ± 0.6 g, were randomly divided into three groups with three replicates (15 fish in each replicate). July 2020 Journal of Environmental Chemical Engineering It is thought that their carotene content functions as a sunscreen protecting chlorophyll and DNA from harmful UV irradiation . Corneal oxidative damage was induced by exposure to UVB radiation at 560 μW/cm 2. Protective effects of Dunaliella salina – a carotenoids-rich alga – against ultraviolet B-induced corneal oxidative damage in mice . The effects of spray-drying of the unicellular microalga Dunaliella salina on its β-carotene content and geometric isomer composition have been studied. But taking beta-carotene doesn’t seem to prevent osteoarthritis. Effects of salinity, pH and growth phase on the protein productivity by Dunaliella salina Yixing Sui Research Group of Sustainable Energy, Air and Water Technology, Department of Bioscience Engineering, University of Antwerp, Antwerp, Belgium Carotenoids are also 48 able to protect photosynthetic organisms from the harmful effects of excess exposure to light by 49 permitting triplet–triplet energy transfer from chlorophyll to carotenoid and by quenching reactive 50 oxygen species (ROS) [2].

Toxic Effect of Aluminum Oxide Nanoparticles on Green Micro-Algae dunaliella salina Ayatallahzadeh Shirazi, M.1, Shariati, 2F.2*, Keshavarz, A. k. and Ramezanpour, Z.3 1G radu teS nof E v im ,Y g R sch lC b I Az U y Lahijan, Iran 2D ep artm nof E v i , Isl cAz dU y L h jb POB x: 16 3 I nte raiol S ug Rsc h , . In addition, the role of glycerol in D. salina as a key organic compatible solute has been used as a research model . Keeping a form of arthritis called osteoarthritis from getting worse. Dunaliella salina is a type of halophile green micro-algae especially found in sea salt fields. In July 2017 this algae caused a color change in the Wagejot, a salty pond in Texel (a small island of the coast of the Netherlands). Several strains of local Dunaliella salina were isolated. There is still a growing demand for the best strain identification and growth conditions optimization for maximum carotenoids production. Dunaliella salina is more effective against cancer than normal beta-carotene. Preventing sunburn in people who are sun sensitive. Dunaliella salina orange-colored water of the salt lake Sivash. The arsenic concentration of the cells increased with an increase of the surrounding arsenic concentration. Plain polystyrene microplastics reduce the toxic effects of ZnO particles on marine microalgae Dunaliella salina. Some strains are noncarotenogenic while other strains may respond differently to applied growth conditions and produce enhanced carotenoid levels. Isolated from the Salt Lake (Tuz Gölü), Turkey Introduction Dunaliella is a green, unicellular, biflagellate alga, belonging to the order Chlamydomonadales (Chlorophyceae, Chlorophyta). Effects of β‐carotene source, Dunaliella salina, and astaxanthin on pigmentation, growth, survival and health of Penaeus monodon. This alga is often found in natural marine habitats where it colours the water red. Abstract. Preventing bronchitis and difficulty breathing in smokers. Dunaliella Salina is a photosynthetic cell requiring sunlight to live; it is highly tolerant of UV radiation due to the photo-protective characteristics of the carotenes it contains. However, Chinese scientists who studied an extract in Dunaliella salina called beta-CDS on human cancer cells, found it was an effective anti-cancer agent. In this study, effect of different percentages of polyploid cells of Dunaliella salina in culture medium, on growth and other biochemical parameters of algae under different salinity levels were investigated. Effect of stressful conditions on the carotenogenic activity of a Colombian strain of Dunaliella salina. Dunaliella salina is a unicellular marine phytoplankton that belongs to the phylum Chlorophyta. Figure 2. The use of P25 TiO 2 NPs in consumer products, their release, and environmental accumulation will have harmful effects on the coastal ecosystems. The Effects of Salinity and Temperature on the Growth of Dunaliella sp. The purpose of this study was to investigate the protective effects of Dunaliella salina (D. salina) on UVB radiation-induced corneal oxidative damage in male imprinting control region (ICR) mice. Dunaliella salina CCAP 19/20 was obtained from the Culture Collection of Algae and Protozoa, ... that applying exogeneous betaine to D. salina cultures can induce a higher production of photosynthetic pigments in D. salina, similar to the effects observed in plants, and that both betaine and Se at adequate concentrations increase significantly the AOA of pigment extracts. Arsenic in D. salina was also greatly affected by addition of phosphorus. Dunaliella salina is the popular microalga for β -carotene production. Scientists have known for a long time that beta-carotene helps to protect against cancer. Dunaliella salina was first recognized by Teodoresco (1905). 189, no. Dunaliella salina, halotorelant unicellular green algae, is the main natural source of beta-carotene. With this compound, Haematococcus protects itself against the harmful effects of sunlight, and gives color to its enemies. In order to monitor the impact of pH an algal samples of D. salina was exposed to different pH regimes (6 -10 pH) along with control (8.5 pH) over a period of 30 days. Dunaliella salina live in high of stress condition. Methods . The sensitivity to TiO 2 NPs may vary depending on the structural property and physiological mechanism of algal species. The use of P25 TiO 2 NPs in consumer products, their release, and environmental accumulation will have harmful effects on the coastal ecosystems. E. Rueda-Puente, T. Castellanos, E. Troyo-Diéguez, J. L. D. de León-Alvarez, and B. Murillo-Amador, “Effects of a nitrogen-fixing indigenous bacterium (Klebsiella pneumoniae) on the growth and development of the halophyte Salicornia bigelovii as a new crop for saline environments,” Journal of Agronomy and Crop Science, vol. Ecology. Hypersaline Lake . Dunaliella salina could survive in media containing a wide range of NaCl concentrations ranging from about 0.05 M to saturation (around 5.5 M). Glycerol is an important osmolyte when Dunaliella survive in various salt environments, and G3pdh is a key enzyme in glycerol metabolism. Dunaliella salina is a type of one-celled green microalgae which was first discovered in 1838 in Southern France.They belong to the category of halophiles.In simple terms, it means, these microalgae only grow in high-salt marine environments.
