摘要
从土样中分离出枯草杆菌,采用梯度平板法,利用链霉素,氯霉素,红霉素,四环素四种抗生素,对自然界中和经过紫外线诱变的菌株进行了抗药性突变株的筛选,我们发现分离出自然状态下的枯草杆菌没有抗药性,而经过紫外线诱变后,能够筛选出对链霉素具有抗药性的菌株。
Bacillus Subtilis resistance to drug mutant was selected with gradient plate in nature and radiated by UV-B.Four kinds of antibiotic such as streptomycin,chloramphenicol,tetracycline,erythromycin were used.Bacillus Subtilis isolated directly from nature can't resist these four kinds of antibiotic.Bacillus Subtilis treated by UV-B can resis streptomycin.
