摘要
以黑暗链霉菌Streptomycetenebrarius163为出发菌株,应用磁场、磁场复合吖啶橙、耐受氨甲酰妥布霉素、磁场复合耐受氨甲酰妥布霉素筛选得到5株高产菌株,经摇瓶发酵复筛后表明。
A tobramycin producing strain, Strepomyces tenebrarius 163 was mutated by magnetic field,magnetic field combined with acriding and resisted by carbamoyltobramycin,carbamoyltobramycin combined with magnetic field.Several high yielding mutants were screened out.After flask rescreening,it is indicated that these mutants′ potency and the percentage of carbamoyltobramycin increased by above 25% than those of the parent strain.
