混合硝酸稀土对链霉菌76-15-60生物合成洁霉素的影响

混合硝酸稀土对链霉菌76-15-60生物合成洁霉素的影响 EFFECT OF MIXTURE OF RERE EARTH ELEMENTS ON LINCOMYCIN BIOSYNTHESIZED BY STREPTOMYCES 76-15-60 李广武 1 first-author 王峰 1 周宇光 1 张春霞 1 为武汉大学生物系微生物专业八○届毕业生 为武汉大学生物系微生物专业八○届毕业生 实验表明混合硝酸稀土对链霉菌76-15-60（Streptomyces 76-15-60）的生理代谢有明显的影响,适当浓度的混合硝酸稀土可以促进该菌洁霉素产量的提高、并能缩短其发酵周期,这可能主要作用在菌的代谢早期,在代谢晚期,作用可能下降。 This paper show that the rare earth elements act on metabolism of Streptomyces76-15 60 evidently. If the rare earth elements at appropriate concentrattons are used, Lincomycin yield may be raised and the fermentation period can be shontened. It seems that the elements mainly function in the early stage of tne metabolism and may lower the effect in the late. 洁霉素 稀土元素 Lincomycin Rare earth elements 1987-03-01 2021-04-01 3
