5S ribosomal RNA sequences of 33 strains of methylotrophic bacteria were determined. Tentative phylogenetic tree was constructed using the maximum topological similarity principle. Strains under study can be divided into 7 separate branches consistently with the current classification of methylotrophic bacteria. More extensive tree was also built to show the position of methylotrophic bacteria with respect to non-methylotrophic ones. One can conclude that the in contrast to obligate methane-oxidizing bacteria, facultative methylotrophic bacteria do not comprise phylogenetically separate domain on the tree.
测定了33株甲基营养菌的5S核糖体RNA序列。利用最大拓扑相似性原则构建了初步的系统发育树。根据目前甲基营养菌的分类，所研究的菌株可分为7个独立的分支。还构建了更广泛的系统发育树以显示甲基营养菌相对于非甲基营养菌的位置。可以得出结论，与专性甲烷氧化菌不同，兼性甲基营养菌在系统发育树上并不构成一个独立的分类域。
