摘要

低能离子注入和UV辐射经真空处理的白色链霉菌均表现出了复杂的生物学效应。探讨了低能离子注入白色链霉菌产生的“马鞍型”注量效应曲线的形成原因。实验结果表明真空因素不是“马鞍型”注量效应曲线形成的原因

推测“马鞍型”注量效应曲线是低剂量辐射产生的HRS/IRR效应。低剂量UV辐照经真空处理的白色链霉菌仅能表现出IRR效应

同时也表现出兴奋效应（存活率>100%）。以抗链霉素突变为指标研究低能离子注入和UV辐射白色链霉菌的诱变效果的结果表明

UV是致白色链霉菌产生抗链霉素突变的有效手段。

Abstract

The results of both 30 keV N + ion implantation and UV irradiation of Streptomyces albus showed com-plicate biological effects. The“saddle shape”pattern of the dose ? dependent curve formed by N + ion implantation with low energy was studied

and it proved that vacuum was not the reason

and in fact

the “saddle shape”curve may be regarded as a HRS/IRR (hyper-radiosensitivity / increased radiaoresistance) effect caused by low dose irradiation. But Streptomyces albus UV irradiated after vacuum treatment only showed IRR effect or hormesis (survival rate >100%). The streptomycin resistance mutation of Streptomyces albus caused by low energy N+ ion implantation and UV irradiation was also studied. The results showed that UV radiation is one effective means for streptomyces albus breeding.
