An actinomycete strain, AM105(T), that produces rifamycin, was isolated from mangrove sediment samples collected from the South China Sea. The strain showed closest 16S rRNA gene sequence similarity to Micromonospora matsumotoense (98.0%). Chemotaxonomic characteristics of the isolate coincided with members of the genus Micromonospora. The value of DNA-DNA relatedness to M. matsumotoense (53.6%) and phenotypic differences from phylogenetically related Micromonospora species indicated that this isolate belongs to a novel species, for which the name Micromonospora rifamycinica sp. nov. is proposed. The type strain is AM105(T) (=CGMCC 4.2495(T)=DSM 44983(T)).
从中国南海采集的红树林沉积物样本中分离出一株产利福霉素的放线菌菌株AM105(T)。该菌株的16S rRNA基因序列与松本小单孢菌（Micromonospora matsumotoense）的相似度最高（98.0%）。该分离株的化学分类特征与小单孢菌属成员一致。与松本小单孢菌的DNA-DNA相关性值（53.6%）以及与系统发育相关的小单孢菌物种的表型差异表明，该分离株属于一个新物种，为此提出了新名称利福霉素小单孢菌（Micromonospora rifamycinica sp. nov.）。模式菌株为AM105(T)（=CGMCC 4.2495(T)=DSM 44983(T)）。
