We isolated two mutants of Pseudomonas aeruginosa PAO with defective iron uptake. In contrast to the wild-type strain, the mutants produced extracellular protease activity in media containing high concentrations of salts or iron and hyperproduced elastase, staphylolytic enzyme, and exotoxin A in ordinary media (Xch mutants). The mutations were located in the 55' region of the chromosome, between the markers met-9011 and pyrD.
我们分离出了两株铁摄取存在缺陷的铜绿假单胞菌PAO突变体。与野生型菌株相比，这些突变体在含有高浓度盐或铁的培养基中产生细胞外蛋白酶活性，并且在普通培养基中过量产生弹性蛋白酶、葡萄球菌溶素和外毒素A（Xch突变体）。这些突变位于染色体的55'区域，在标记met-9011和pyrD之间。
