摘要
通过对P .rhodozyma 4 - 2 6的虾青素摇瓶发酵条件包括接种比、通气量和温度等 ,以及培养基主要组分的优化 ,得到最优培养基及培养条件。在此条件下发酵 72h ,虾青素量可达 13 4 5μg/ml或 146 5μg/gCDW ,较优化前提高 1 4 8倍。
The fermentation conditions for the strain P.rhodozyma 4-26 were optimized, including inoculation, aeration, cultivation temperature and the main composition of the medium, etc. Under the optimal conditions, the yield or astaxanthin was 13 45μg/ml of 1465μg/gCDW, which was improved 1 48 times compared with unoptimization.
