Introduction 32 Natural carotenoids have gained increasing attention in recent years because of their health 33 benefits compared to synthetic β-carotene and lutein are major carotenoids of D. salina and account for 90% and 5% of total carotenoids… In general, Dunaliella salina species are ubiquitous in saline environments, and often multiple species occur in the same habitat. Natural Mixed Carotenoids are among nature’s safest and best antioxidants. Dunaliella Salina is the best source in nature of beta-carotene, alpha-carotene, cryptoxanthin, zeaxanthin, lutein and lycopene. This natural beta-carotene offers a number of unique health benefits for the heart, eyes, and skin. Dunaliella salina is very rich in carotenoids and vitamins A and E. It acts as an antioxidant and moisturizer*. Dunaliella salina, a halotolerant chlorophyte, is one of the richest sources of natural carotenoids and, similar to various members of the Chlorophyceae, accumulates a high content (up to 10% of the dry biomass) of carotenoids under conditions that are sub-optimal for growth i.e., high light intensity, sub-optimal temperatures, nutrient limitation and high salt concentrations. TY - THES. T1 - Metabolomics of carotenoid accumulation in Dunaliella salina. D. salina contains a potent mixture of the most important carotenoids, including: B-carotene, A-carotene, lutein, zeaxanthin, astaxanthin and cryptoxanthin. Betatene ® is available in excellent quality for applications in dietary supplements as well as functional foods and beverages. Betatene ® is a naturally sourced beta-carotene derived from algae (Dunaliella salina) and part of the broad beta-carotene product range BASF offers. This green alga is a unicellular ovoid biflagellate (Figure 1.1). However, carotenoids responsible for the red colouration in D. salina are found in algal chloroplasts, whereas halophilic archaea also occupying hypersaline lakes have red pigments dispersed throughout the cell membrane. Beta-Carotene-Rich Extract from Dunaliella salina is produced by Dunaliella salina, an extreme halotolerant alga, which inhabits natural and man-made salt lakes and ponds. The proven health benefits of dunaliella salina carotenoid will leave you with a smile. This work proposes a sustainable process to maximise the potential of Dunaliella salina for the production of distinct fractions of carotenoids, glycerol, polar lipids and proteins, which may contribute to improve the revenues of the microalgae industry.

The carotene-rich algae is harvested and concentrated, and the carotenoids are extracted using an essential oil rich in d-limonene. Cl.7 C07C403/24; C12N1/12 Introduction Microalgae are among the fastest growing auto-trophs on the earth, which utilize commonly available material for growth. The microalga Dunaliella salina is the best commercial source of natural β‐carotene. Dunaliella salina extract is an ideal ingredient in skin care because it’s full of active ingredients. Total carotenoi … Dunaliella salina is a type of halophile green micro-algae especially found in sea salt fields. 2000). Among the carotenoids, astaxanthin was found to be more effective than β-carotene as an antioxidant and a better agent to destroy free radicals than other carotenoids [9,10]. On the industrial scale, β-carotene is obtained in molds Blakeslea trispora and alga Dunaliella salina cultivations. Dunaliella salina is natural form of beta-carotene derived from the ocean and it's a natural microalgae. One type of microalgae that is potential to be developed as a natural feed is Dunaliella salina. Dunaliella salina was first recognized by Teodoresco (1905). Buy amazing dunaliella salina carotenoid on at irresistible offers and enhance your well-being. Dunaliella salina strain and stock preparation The Dunaliella salina (EGEMACC-24) strain was obtained from Ege University Microalgae Culture Collection, Turkey. 1982), when stressed.These carotenoids are stored in lipid globules. Good HPLC-based methods already exist for the separation, detection and quantification of a wide variety of carotenoids (Fraser et al. Here we investigated the effects of high intensity blue, red and white light from light emitting diodes (LED) on the production of carotenoids by strains of D. salina under nutrient sufficiency and strict temperature control favouring growth. India is a tropical country with abundant coastal area and superfluous solar energy Factors that influence affect the density and carotenoids of D. salina is the intensity of light because it has an important role in the process of photosynthesis. Non-stressed cells are dominated by the chloroplast, emitting red fluorescence originating from the chlorophyll in the thylakoid mem-branes. They also have a large potential for biotechnological processes such as expressing of foreign proteins and treatment of wastewater. Dunaliella is a unique unicellular species of algae harvested from the Dead Sea containing rich concentrations of carotenoids (mainly Beta-Carotene), antioxidants and … Ortega Méndez CANARAGUA, S.A., Grupo AGBAR, Las Palmas de Gran Canaria , 35007 , Islas Canarias , Spain Phone: Tel. This alga is often found in natural marine habitats where it colours the water red. The halotolerant photoautotrophic marine microalga Dunaliella salina is one of the richest sources of natural carotenoids. Dunaliella salina stores secondary carotenoids (predomi-nantly β-carotene) in lipid globules in the chloroplast when cultivated under stress conditions. Optimal growth temperature for D. salina was 22 degrees C (3.06 x 10(6) cells mL(-1)) and 26 degrees C for D. viridis (4.04 x 10(6)cells mL(-1)). It protects and softens the skin.
