【Abstract】 This paper investigated the effects of carbon sources and concentration on the growth of Phaffia rhodozyma and the accumulation of astaxanthin. The result showed that the concentration of 20～30 g/L was beneficial to the growth of Phaffia rhodoyma and the accumulation of astaxanthin. Among the carbon sources investigated, molasses was the most beneficial to cell growth while xylose was the most beneficial to the accumulation of astaxanthin. When mixed carbon soource of molasses and xylose was used, the output of astaxanthin reached 1.9 mg/L.更多还原
