摘要: 对富产虾青素的红法夫酵母(Phaffia rhodozyma)CS0217的培养条件进行初步研究,确定其最佳培养基组成为:葡萄糖2.5%、果糖2%、酵母膏0.5%;在发酵液初始pH为8.0、接种量为20%、振荡速度160r/min条件下,经过168h振荡培养后,虾青素的产量为9414μg/L。

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.
