720 bacteria from 18 water samples were isolated under conditions which are expected to be selective for methylotrophic bacteria. The water samples derived from 11 different water plants including 5 which had to treat methane containing groundwater. All isolates had been characterized by 130 properties using the morphological features of the colonies and the cells as well as physiological and biochemical tests. Numerical and classical principles of taxonomy were applied to the data. Only 20% of the isolated bacteria pointed out to be methylotrophic, even the portion of obligate methylotrophic organisms was only 1%.
在预期对甲基营养菌具有选择性的条件下，从18个水样中分离出720株细菌。这些水样来自11个不同的水厂，其中5个水厂必须处理含甲烷的地下水。利用菌落和细胞的形态特征以及生理生化测试，对所有分离菌株进行了130项特性的表征。将分类学的数值和经典原理应用于这些数据。结果发现，只有20%的分离细菌是甲基营养菌，其中专性甲基营养菌的比例仅为1%。
