The halotolerant photoautotrophic marine microalga Dunaliella salina is one of the richest sources of natural carotenoids. Beta-carotene is a pigment, belonging to a family of naturally occurring yellow, orange and red pigments, which are collectively called as carotenoids, found in various fruits, cruciferous, yellow and dark – green vegetables and also abundantly in algae such as Dunaliella salina. 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)). Dunaliella is a unique unicellular species of algae harvested from the Dead Sea containing rich concentrations of carotenoids (mainly Beta-Carotene), antioxidants and … Dunaliella salina is a type of halophile green micro-algae especially found in sea salt fields. Carotenoids are naturally found in fruits and vegetables and considered one of the most important daily nutrients for people to consume every day. Additionally, different species of Dunaliella can accumulate significant amounts of valuable fine chemicals such as carotenoids, glycerol, lipids, vitamins, minerals and proteins. This alga is often found in natural marine habitats where it colours the water red. Carotenoids and fatty acids both possess long carbon backbones; however, the relationship between carotenoid and fatty acid metabolism is controversial and remains poorly understood in microalgae. This green alga is a unicellular ovoid biflagellate (Figure 1.1). The green alga Dunaliella salina can accumulate high amount of β-carotene which is more than 14% of its dry weight in its cup shaped chloroplast when subjected to abiotic stresses. Dunaliella salina was first recognized by Teodoresco (1905). Dunaliella salina is a microalgae occurring naturally in a number of locations worldwide. Dunaliella salina extract is an ideal ingredient in skin care because it’s full of active ingredients. 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. When the cells are stressed, the red fluorescence Name: Dunaliella salina powder: Function: Dunaliella salina was thought to be responsible for the red colouring of salted brines. Dunaliella salina is natural form of beta-carotene derived from the ocean and it's a natural microalgae. Ortega Méndez CANARAGUA, S.A., Grupo AGBAR, Las Palmas de Gran Canaria , 35007 , Islas Canarias , Spain Phone: Tel. Under different abiotic-stress conditions, the unicellular green microalga Dunaliella salina accumulates large amounts of carotenoids which are accompanied by fatty acid biosynthesis. This natural beta-carotene offers a number of unique health benefits for the heart, eyes, and skin. Good HPLC-based methods already exist for the separation, detection and quantification of a wide variety of carotenoids (Fraser et al. Carotenoids are also naturally found in some fruits and vegetables and are considered one of the most important daily nutrients for … Dunaliella salina is a single celled, salt-water micro-algae that accumulates massive amounts of carotenoids under appropriate growth conditions. 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. Dunaliella salina contains a potent mixture of important carotenoids, includ- ing: betacarotene, alpha-carotene, lutein, zeaxanthin, and cryptoxanthin. β-carotene and lutein are major carotenoids of D. salina and account for 90% and 5% of total carotenoids… They also have a large potential for biotechnological processes such as expressing of foreign proteins and treatment of wastewater.
