Corneal oxidative damage was induced by exposure to UVB radiation at 560 μW/cm 2. The unicellular marine alga, Dunaliella salina 19/30 was grown in seawater containing an inorganic arsenic concentration (Na 2 HAsO 4) up to 2000 mg dm −3. For the first time, Milko (1963) reported that Dunaliella contains high concentrations of β‐carotene and later it was also recommended as a commercial source of glycerol (Ben‐Amotz 1980). Dunaliella salina live in high of stress condition. The sensitivity to TiO 2 NPs may vary depending on the structural property and physiological mechanism of algal species. Effects of β‐carotene source, Dunaliella salina, and astaxanthin on pigmentation, growth, survival and health of Penaeus monodon. Read "COMBINED TOXIC EFFECTS OF TYPICAL MUTAGENS – DIMETHYLPHENOL, TRIBROMETHANE AND DINITROANILINE, ON UNICELLULAR GREEN ALGAE DUNALIELLA SALINA, Journal of Food Safety" on DeepDyve, the largest online rental service for scholarly research with thousands of academic publications available at your fingertips. 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. Preventing sunburn in people who are sun sensitive. 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). The sensitivity to TiO 2 NPs may vary depending on the structural property and physiological mechanism of algal species. Dunaliella salina orange-colored water of the salt lake Sivash. Isolated from the Salt Lake (Tuz Gölü), Turkey Introduction Dunaliella is a green, unicellular, biflagellate alga, belonging to the order Chlamydomonadales (Chlorophyceae, Chlorophyta). Dunaliella salina is a unicellular marine phytoplankton that belongs to the phylum Chlorophyta. There is still a growing demand for the best strain identification and growth conditions optimization for maximum carotenoids production. 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. The unmatched carotenoid content of Dunaliella provides a wide range of health-supporting effects. The efficacy of a range of synthetic and natural antioxidants in preventing degradation of β-carotene has been determined. Plain polystyrene microplastics reduce the toxic effects of ZnO particles on marine microalgae Dunaliella salina. Arsenic in D. salina was also greatly affected by addition of phosphorus. The arsenic concentration of the cells increased with an increase of the surrounding arsenic concentration. 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. In addition, the role of glycerol in D. salina as a key organic compatible solute has been used as a research model . 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. July 2020 Journal of Environmental Chemical Engineering With this compound, Haematococcus protects itself against the harmful effects of sunlight, and gives color to its enemies. The cells survived even at 5000 mg dm −3. M Boonyaratpalin. 2 of 13 47 excitation energy to chlorophylls, which have poor absorption in this range. This alga is often found in natural marine habitats where it colours the water red. 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 , . Ecology. The use of P25 TiO 2 NPs in consumer products, their release, and environmental accumulation will have harmful effects on the coastal ecosystems. Hypersaline Lake . These cultures were neither axenic nor unialgal and contained mainly D. salina as well as low numbers of D. viridis. 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. 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). 135 A. ocellatus, weighing 25.6 ± 0.6 g, were randomly divided into three groups with three replicates (15 fish in each replicate). 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]. But taking beta-carotene doesn’t seem to prevent osteoarthritis. Glycerol is an important osmolyte when Dunaliella survive in various salt environments, and G3pdh is a key enzyme in glycerol metabolism. The effects of spray-drying of the unicellular microalga Dunaliella salina on its β-carotene content and geometric isomer composition have been studied. Scientists have known for a long time that beta-carotene helps to protect against cancer. It is thought that their carotene content functions as a sunscreen protecting chlorophyll and DNA from harmful UV irradiation . 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. Dunaliella salina, halotorelant unicellular green algae, is the main natural source of beta-carotene. Known for its antioxidant activity because of its ability to create large amount of carotenoids, it is used in cosmetics and dietary supplements. However, beta-carotene is unlikely to have much effect on sunburn risk in most people. Anticancer effect of Dunaliella salina under stress and normal conditions against skin carcinoma cell line A431 in vitro Emtyazjoo Mo 1; Moghadasi Z. 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. Dunaliella salina is more effective against cancer than normal beta-carotene. Preventing bronchitis and difficulty breathing in smokers. Samples of Dunaliella salina were collected from the growth ponds ofWesfarmers Algal Biotechnology Pty Ltd at Hutt Lagoon, Western Australia, and were established and maintained at the collection salinity (25 to 30% NaCl) in 15 em deep, 15 L mini-ponds in a glasshouse. Dunaliella salina are found in high salinity environments such as salted brines, salt evaporation ponds, and hypersaline lakes. Survival stage. Dunaliella salina is a type of halophile green micro-algae especially found in sea salt fields. 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). 189, no. The use of P25 TiO 2 NPs in consumer products, their release, and environmental accumulation will have harmful effects on the coastal ecosystems. 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.
