β-Carotene-production methods, biosynthesis from Phaffia rhodozyma, factors affecting its production during fermentation, pharmacological properties: A review.

β-Carotene is the most treasured provitamin A carotenoid molecule exhibiting antioxidant and coloring properties and significant applications in the food, pharmaceutical, and nutraceutical industries. β-Carotene has many biological functions within the human body; however, it is not synthesized within the human body, so its requirements are fulfilled through food and pharmaceuticals. Its manufacturing via chemical synthesis or extraction from plants offers low yields with excessive manufacturing expenses, which attracted the researchers toward microbial production of β-carotene. This alternative provides higher yield and low expenses and thus is more economical. Phaffia rhodozyma is a basidiomycetous yeast that is utilized to prevent cardiovascular diseases and cancer and to enhance immunity and antiaging in people. This paper reviews the methods of production of β-carotene, biosynthesis of β-carotene fromP. rhodozyma, factors affecting β-carotene production during fermentation, and pharmacological properties of β-carotene.
