| 摘 要： | 研究了葡萄糖、蔗糖和果糖对小球藻(Chlorella zofingiensis)异养生长及产虾青素的影响，结果表明，在糖浓度为20g/L时，细胞生长较快，但干重较小，虾青素含量较低；在糖浓度为50g/L时，细胞生长较慢，但干重较大，虾青素含量较高。3种碳源中蔗糖和葡萄糖效果较好，在蔗糖浓度为50g/L时，虾青素含量和产量分别达到0.94 mg/g和9.61 mg/L。

| Abstract: | 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. |
