Two unusual strains of budding bacteria were isolated on a Millipore Pseudomonas Count Water Tester during routine monitoring of Pseudomonas aeruginosa counts in a swimming pool. The first isolate has been identified as Blastobacter sp. It was a yellow-pigmented, Gram negative rod-shaped organism with a polar holdfast by which it attached to solid surfaces or other cells to form rosettes. The cells reproduced by asymmetric division or budding at the free pole of the cell, producing motile daughter cells with a single polar flagellum. The second isolate, which has not yet been identified, was a red-pigmented, Gram negative rod-shaped organism which produced one or more buds at each pole of the cell. Cell division appears to occur by both binary fission and by budding. Both organisms were strict aerobes, catalase and oxidase positive and did not produce acid from glucose in Hugh and Leifson medium.
在对游泳池中铜绿假单胞菌数量进行常规监测期间，通过密理博假单胞菌计数水质检测仪分离出了两种不寻常的出芽细菌菌株。第一种分离菌株已被鉴定为芽殖杆菌属。它是一种黄色色素沉着、革兰氏阴性的杆状生物，具有一个极性固着器，通过它附着在固体表面或其他细胞上形成玫瑰花结。细胞通过不对称分裂或在细胞的自由极出芽进行繁殖，产生具有单个极鞭毛的运动子细胞。第二种分离菌株尚未鉴定，它是一种红色色素沉着、革兰氏阴性的杆状生物，在细胞的每个极产生一个或多个芽。细胞分裂似乎通过二分裂和出芽两种方式进行。两种生物均为严格需氧菌，过氧化氢酶和氧化酶呈阳性，在休伊和利夫森培养基中不能从葡萄糖产生酸。
