从几个活性污泥样品中分离出大量的气单胞菌菌株。有些菌株在分离后立即表现出弱的或负的氧化酶活性，从乳糖中产生酸和气体，在Endo琼脂上形成金属菌落，并具有IMViC [吲哚，甲基红，Voges-Proskauer，柠檬酸]反应，与E. coli，进一步的生化鉴定表明，这些菌株属于最近描述的A. sobria所有菌株均无固氮酶活性。和A. sobria两个分类群的几乎所有菌株都对氨苄青霉素和青霉素V具有抗性，并且两者的67%都是β-溶血性的
Strains of Aeromonas were isolated in high numbers from several activated sludge samples. Immediately after isolation, some displayed only weak or negative oxidase activity, produced acid and gas from lactose, formed metallic colonies on Endo agar and had IMViC [indole, methyl red, Voges-Proskauer, citrate] reactions which were identical with those of E. coli, further biochemical characterization showed that these belonged to the recently-described A. sobria. Nitrogenase activity was absent in all strains of A. hydrophila and A. sobria. Almost all strains of both taxa were resistant to ampicillin and penicillin V and 67% of both were .beta.-hemolytic.
