The spiramycin producing strain Streptomyces spiramyceticus XCH1-23 was treated with UV irradiation. The 2-deoxy-D-glucose tolerant mutants, valine tolerant mutants, soybean oil tolerant mutants and SPM resistant mutants were screened by means of rational selection and natural selection, respectively.
以螺旋霉素链霉菌XCH1-23为出发菌株,通过紫外线诱变处理,结合理性选育和自然分离,筛选得到耐2-去氧葡萄糖、缬氨酸和耐豆油突变株,在此基础上,筛选得到抗自身产物的突变株。
