Legionella pneumophila (Legionnaires disease bacterium) of serogroup 1 was isolated from an algal-bacterial mat community growing at 45 degrees C in a man-made thermal effluent. This isolate was grown in mineral salts medium at 45 degrees C in association with the blue-green alga (cyanobacterium) Fischerella sp. over a pH range of 6.9 to 7.6. L. pneumophila was apparently using algal extracellular products as its carbon and energy sources. These observations indicate that the temperature, pH, and nutritional requirements of L. pneumophila are not as stringent as those previously observed when cultured on complex media. This association between L. pneumophila and certain blue-green algae suggests an explanation for the apparent widespread distribution of the bacterium in nature.
从一个在人造热排放物中于45摄氏度生长的藻菌垫群落中分离出了血清型1的嗜肺军团菌(军团病杆菌)。该分离株在45摄氏度的矿物盐培养基中与蓝绿藻(蓝细菌)费氏藻属共同生长,pH范围为6.9至7.6。嗜肺军团菌显然利用藻类细胞外产物作为其碳源和能源。这些观察结果表明,嗜肺军团菌的温度、pH和营养需求并不像之前在复杂培养基上培养时所观察到的那样严格。嗜肺军团菌与某些蓝绿藻之间的这种关联为该细菌在自然界中明显广泛分布提供了一种解释。
