Phylogenetic evidence derived from a 16S ribosomal DNA analysis indicated that the type strain of Micrococcus agilis, DSM 20550 (= ATCC 966 = CCM 2390), is less closely related to the type species of the genus Micrococcus, Micrococcus luteus, than to the type species of the genus Arthrobacter, Arthrobacter globiformis, and related Arthrobacter species. The phylogenetic position of M. agilis is supported by the presence of peptidoglycan variation A3 alpha and by the presence of MK-9(H2) as the major isoprenolog, a characteristic also found in strains of A. globiformis, Arthrobacter crystallopoietes, Arthrobacter atrocyaneus, Arthrobacter citreus, Arthrobacter aurescens, Arthrobacter ilicis, Arthrobacter ureafaciens, Arthrobacter oxydans, Arthrobacter histidinolovorans, and Arthrobacter nicotinovorans. The last six species and M. agilis are characterized by the presence of threonine in the interpeptide bridge of the peptidoglycan. Threonine has not been found in the peptidoglycans of other Arthrobacter species or in members of the genus Micrococcus. Despite the fact that a morphological life cycle is not known, these data support the proposal that M. agilis should be transferred to the genus Arthrobacter as Arthrobacter agilis comb. nov.
基于16S核糖体DNA分析得出的系统发育证据表明，敏捷微球菌（Micrococcus agilis）的模式菌株DSM 20550（= ATCC 966 = CCM 2390）与微球菌属（Micrococcus）的模式种藤黄微球菌（Micrococcus luteus）的亲缘关系，不如与节杆菌属（Arthrobacter）的模式种球形节杆菌（Arthrobacter globiformis）及相关节杆菌物种的亲缘关系密切。敏捷微球菌的系统发育位置得到肽聚糖变异型A3α的存在以及以MK-9（H2）作为主要类异戊二烯醇的支持，球形节杆菌、产晶节杆菌（Arthrobacter crystallopoietes）、深蓝节杆菌（Arthrobacter atrocyaneus）、柠檬节杆菌（Arthrobacter citreus）、金色节杆菌（Arthrobacter aurescens）、冬青节杆菌（Arthrobacter ilicis）、尿素节杆菌（Arthrobacter ureafaciens）、氧化节杆菌（Arthrobacter oxydans）、组氨酸营养节杆菌（Arthrobacter histidinolovorans）和烟碱营养节杆菌（Arthrobacter nicotinovorans）的菌株也具有这一特征。后六个物种和敏捷微球菌的特征是肽聚糖的肽间桥中存在苏氨酸。在其他节杆菌物种的肽聚糖或微球菌属成员中未发现苏氨酸。尽管尚不清楚其形态生命周期，但这些数据支持将敏捷微球菌作为球形节杆菌（Arthrobacter agilis）新组合转入节杆菌属的提议。
