Preventing bronchitis and difficulty breathing in smokers. of Dunaliella salina 22 4.2 Effect of NaNO 3 concentration and light intensity to the total ... are highly reactive molecules and they can cause harmful reactions for example uncontrolled oxidation in the body damages fat, genetic materials, and cell membranes including cataracts and cardiovascular diseases. Some strains are noncarotenogenic while other strains may respond differently to applied growth conditions and produce enhanced carotenoid levels. Survival stage. Dunaliella salina is the popular microalga for β -carotene production. Figure 2. Corneal oxidative damage was induced by exposure to UVB radiation at 560 μW/cm 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 unmatched carotenoid content of Dunaliella provides a wide range of health-supporting effects. 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). 2 of 13 47 excitation energy to chlorophylls, which have poor absorption in this range. 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. After its discovery in the 18th century, D. salina was found in different locations of Europe and Algiers. Dunaliella is a unique unicellular species of algae containing rich concentrations of carotenoid enzymatic pigments (mainly Beta-Carotene), antioxidants, essential fatty acids, vitamins, minerals & trace elements. 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. Dunaliella salina is a type of halophile green micro-algae especially found in sea salt fields. However, beta-carotene is unlikely to have much effect on sunburn risk in most people. The sensitivity to TiO 2 NPs may vary depending on the structural property and physiological mechanism of algal species. Preventing sunburn in people who are sun sensitive. Abstract.
