Effects of Carbon Sources on the Production of Astaxanthin by Chlorella zofingiensis in the Dark
不同碳源对小球藻Chlorella zofingiensis异养产虾青素的影响

This paper investigated the effects of carbon sources on the growth of Chlorella zofingiensis and the production of astaxanthin. The result showed that the concentration of 20g/L was beneficial to the growth of Chlorella zofingiensis, but on the this concentration biomass and astaxanthin content was low; on the concentration of 50g/L, the growth is slower, but biomass and astaxanthin content was high . Among the three carbon sources investigated , sucrose and glucose were more beneficial to growth and production of astaxanthin than fructose. When 50g/L sucrose was used , the astaxanthin content and astaxanthin yield was 0.94 mg/g and 9.61 mg/L respectively.
