摘要

用ＥＳＲ波谱仪测定了室温下氮离子注入核糖霉素产生菌、卡那霉素产生菌和卡那霉素抗株产生菌所引起的自由基．实验结果表明：氮离子注入上述三种菌种能产生大量的自由基。自由基产额随注入剂量的增加而增加。菌种死亡率随自由基产额的增加而上升。

Abstract

Under room temperature the electron spin resonance （ESR） spectrometer was used to study the free radical formation in antibiotic-producers （e.g. Streptomyces ribosidificus

Streptothyces kanamyceticus and the phage-resistant culture of Streptomyces kanamyceticus） in order to investigate antibiotic-producer mutagenesis breeding induced by N ion implantation.The results show that a great number of free radicals can be induced by N ion implantation and the yields increase with implanting dose. The death rate of antibiotic-producers also rises due to the increase of the free radical yields.
