摘要
应用均匀设计的方法，对光合细菌球形红杆菌７－１菌株的类胡萝卜素生产的培养基组成进行优化，得到的优化条件为：乳酸钠１．２％；谷氨酸钠０．７％；硫酸镁１００ｍｇ／Ｌ；硫酸铁１５ｍｇ／Ｌ；酵母膏０．２％，在此条件下，类胡萝卜素产量比优化前提高６１％．
Uniform design was employed totest the influence of five medium components onthe fermentation of carotenoids by Rhodobacter sphaeroides,strain 7-1.The resultswere sodium lactate 1.2%(w/v),sodium glutamate 0.7%(w/v),MgSO4· 7H2O100mg/L.Fe2(SO4)315mg/L and yeast extracts 0.2%(w/v).Under this condition,theyield of carotenoids increased by 61%compared with data before.
