Double cross - over strains aved24 and avec9 were obtained after growth of several generations on mym plate with or without antibiotics selection . genomic dna of double cross - over strains aved24 and avec9 were extracted and southern hybridization were performed 分別提取同源雙交換茵株aved24和avec9基因組dna ,通過薩瑟恩( southern ) dna印跡雜交,結果證明l

The transformants were cultivated and the harvested cells were used in the procedure of conjugation by which the recombinant plasmid pid03 and pc05 were introduced into streptomyces avermitilis s - 2 respectively 經過在mym平板上的傳代和抗性標記的篩選分別得到了同源雙交換的菌株aved24和avecg 。
