抗发酵药

In order to find new kinds of antibacterial agents, a primary screening model has been set with the DNA gyrase B subunit as a target, and then the active compounds of positive strain were purified. From Mycobacterium phlei, we isolated a novobiocin supersensitive mutant M.phlei SS12 and a resistant ~mutant M.phlei RR11 with NTG and UV.

实验采用Mycobacteriumphlei为出发菌株，利用NTG和紫外线复合诱变得到新生霉素特异性的超敏菌株M.phleiSS12和耐药菌株M.phleiRR11，建立了以DNA回旋酶B亚基为靶点的抗结核药物的筛选模型；并应用此模型对1600株真菌和100株放线菌发酵液进行了初筛，获得了38株阳性菌，阳性率为2.4%；对阳性菌株3277的发酵液进行了提取分离，得到X1和X2两个活性化合物。
