补充资料：溶解氧
分子式：
CAS号：
性质：好氧微生物的代谢需要氧，而且所需的是溶解在培养液中的氧即溶解氧。只有提供了必要的溶解氧，微生物才能达到合适的代谢活性。氧作为生化反应电子传递链的最终受体。在基质氧化过程中微生物可获得能量。但氧在水中的溶解度很小，如在25℃时，101.325kPa的空气在纯水中氧的饱和溶解度仅为8.47mg/L，在4～33℃范围内，0.1MPa的空气在水中的氧饱和溶解度可用468/（31.6+t）mg/L估算，此处t为系统温度，℃。为了将空气中的氧溶解于培养液中，实验室里用摇瓶机促进空气与培养液接触，增强氧的溶解速率；在中试车间或工厂，向发酵罐通入无菌压缩空气，并装有搅拌器，增加气液接触面积与时间。
