培养基优化提高酵母胞内核黄素含量

Increasing the Intracellular Riboflavin of Yeast by Optimizing Culture Medium

研究了培养基中不同成份对酵母胞内核黄素含量的影响.结果表明:金属离子、氮源、生长因子对酵母胞内核黄素含量有着显著影响,培养基优化配方为:MgSO4·7H2O 1.1g/L,CoSO4·7H2O 28mg/L,CuSO4·5H2O 0.01 mg/L,MnCl2 0.02mg/L,ZnSO4·7H2O34mg/L,FeSO4·7H2O 14 mg/L,生物素100μg/L,硫胺素4mg/L.添加豆油对酵母胞内核黄素含量有明显的促进作用.
