Abstract
We found that sodium selenate added to F-G cysteine iron agar enhanced the growth of Legionella pneumophila (Philadelphia 1 strain), with visible colonies at 18 h of incubation. The optimum enhancement of growth was found to occur at a concentration of 5 to 10 microgram of selenium per ml as sodium selenate; enhanced growth, up to 22 times the number of colonies on F-G cysteine iron agar without selenate, was observed at 36 h.
摘要
我们发现，添加到F-G半胱氨酸铁琼脂中的硒酸钠可促进嗜肺军团菌（费城1株）的生长，在培养18小时时可观察到可见菌落。发现以硒酸钠形式存在的硒浓度为每毫升5至10微克时生长促进效果最佳；在36小时时观察到生长增强，菌落数量是不含硒酸钠的F-G半胱氨酸铁琼脂上菌落数量的22倍。
