Studies on Astaxanthin Production by Phaffia Rhodozyma Fermentation
Abstract: Astaxanthin is a high-value-additive,which has wide applications in food,medicine and cosmetics.Phaffia rhodozyma is one of the microorganisms which produce natural astaxanthin.The methoud of astaxanthin fermentation by Phaffia rhodozyma and the conditions of production was introducted and studied in paper. single factor design experiments shows that the best nitrogen is peptone,the best carbon is beer wort. Response surface design were used to optimize the components of fermentation. In this paper , the research advances and methods in fermentation optimization of Phaffia rhodozyma are summarized. Furthermore, strategy was proposed to solve the problems in larger scale commercial production of astaxanthin.
