An antibiotic obtained from the actinomycete Streptomyces erythreus; effective against many Gram-positive bacteria and some Gram-negative.
从放射链霉菌中得到的抗生素；有效的抵抗革兰阳性细菌和一些革兰阴性细菌的药物。
The higher yielding strain was obtained through the reverse mutant of a zero producer of Streptomyces erythreus UV 80 by NTG treatment.
利用亚硝基胍（NTG）对红霉素链霉菌（S.erythreusUV80）活性菌株进行回复突变，获得了红霉素高产量变株。
The spores of Streptomyces erythreus were implanted by nitrogen ions with the energy of 40 to 60 keV. The survival rate decayed exponentially with the increasing of ion implantation dose. The relationship between survival rate and dose was formulated by imitation in computer.
用40keV、60keV的N＋离子束对红霉素产生菌进行了离子注入，发现菌株存活率随注入剂量的增加呈指数衰减，并拟合了存活率&剂量公式。
