16 SrDNA序列数据的节杆菌属的11种和微球菌属的4种，并与其他成员的节杆菌谱系内的放线菌目。这两个属的成员的混合和放置在这两个属的辐射，如先前所建议的16 S rRNA编目的鲑肾杆菌，得到证实。分支模式揭示了几种密切相关的生物，它们聚集在节杆菌属和微球菌属的模式种周围;这些物种被认为是“核心生物”。然而，有几个菌种分支在核心生物的辐射范围之外;这些菌种包括克里斯汀微球菌、嗜盐微球菌，以及如前所述的久坐微球菌和M.西宫种由于支持将这四个种从微球菌属中排除的表型数据仍然缺乏分类学结论，应等待更彻底的比较研究。
16S rDNA sequence data was obtained for 11 species of Arthrobacter and 4 species of Micrococcus and compared with that from other members of the arthrobacterial lineage within the order Actinomycetales. The intermixing of members of these two genera and the placement of Renibacterium salmoninarum within the radiation of these two genera, as previously suggested by 16S rRNA cataloguing, is confirmed. The branching pattern reveals several closely related organisms that cluster around the type species of Arthrobacter and Micrococcus; these species are considered 'core organisms'. A few species, however, branch outside the radiation of core organisms; these include Micrococcus kristinae, Micrococcus halophilus, and, as previously indicated, Micrococcus sedentarius and M. nishinomiyaensis. As phenotypic data that would support the exclusion of these four species from the genus Micrococcus are still lacking taxonomic conclusions should await more thorough comparative studies.
