【摘要】 通过对P rhodozyma4 - 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 1465μg/gCDW ,较优化前提高 1 4 8倍。更多还原

【Abstract】 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 45?μg/mL or 1?465?μg/g CDW, which was improved 1 48 times compared with unoptimization更多还原
