Abstract: The production conditions for astaxanthin by Phaffia rhodozyma CS0217 were investigated. The results showed that the optimal medium compositions are glucose 2.5 %,fructose 2 % and yeast extract 0.5 %,and the optimal conditions for producing astaxanthin are initial pH 8.0,inoculum size 20 % and rotational speed 160 r/min. After 168 h fermentation,the productivity of astaxanthin is 9414μg/L.

Key words: astaxanthin, Phaffia rhodozyma, fermentation
