During recent years, there was growing demand in using microalga valuable products such as β-carotene in health care. β-Carotene has anti-cancer and anti-aging properties for human. In Dunaliella salina cells, β-carotene has a major protecting role for biomolecules, when the production of reactive oxygen species elevated. In the present study, we investigated the influence of the four most effe...

Although B-carotene has been considered to be a key cancer preventive agent in green and yellow vegetables, other types of carotenoids, such as a-carotene, may also contribute to anticarcinogenic action, since these carotenoids usually coexist with/~-carotene and are detectable in human blood and tissues. In this study, we compared the inhibitory effect of natural a-carotene, obtained from palm...

beta-carotene is a carotenoid and known as the most famous natural pigment. microalgae are the most important sources for beta-carotene production. due to the high sterilization cost of pure culture, in this study for the first time, growth, amounts of beta-carotene and chlorophyll in caspian sea microalgae under nutrient deficiencies stress, have been measured and compared with pure microalgae...

Lutein, a dihydroxy derivative of -carotene ( , -carotene), is the most abundant carotenoid in photosynthetic plant tissues where it plays important roles in light-harvesting complex-II structure and function. The synthesis of lutein from lycopene requires at least four distinct enzymatic reactions: and -ring cyclizations and hydroxylation of each ring at the C-3 position. Three carotenoid hydr...

Luteal cells were isolated from mid-luteal heifer ovaries by collagenase digestion. Cells were cultured with DMEM/Ham's F12 medium in serum pre-treated plastic culture dishes for periods of up to 11 days. As beta-carotene is almost completely insoluble in all polar solvents, it was added to cultures in either dimethyl sulphoxide (DMSO), tetrahydrofuran (THF) or as high-density lipoprotein (HDL)...
