摘要：

A novel actinobacterial strain, designated strain NEAU-JM2(T), was isolated from volcanic sediment collected from Longwan, Jilin province, north China and characterized using a polyphasic approach. The strain was found to have morphological and chemotaxonomic characteristics typical of the members of the genus Micromonospora. Phylogenetic analysis of the16S rRNA gene sequence also indicated that strain NEAU-JM2(T) should be classified in the genus Micromonospora and showed that close relatives are Micromonospora maoerensis NEAU-MES19(T) (99.5 %) and Micromonospora matsumotoense JCM 9104(T) (98.8 %). However, phylogenetic analysis based on the gyrB gene sequence showed that the isolate forms a separate subclade away from the close relatives in the neighbour-joining tree and also recovered with the maximum-likelihood algorithm. The low level of DNA-DNA relatedness allowed the isolate to be differentiated from M. maoerensis NEAU-MES19(T) and M. matsumotoense JCM 9104(T). Furthermore, strain NEAU-JM2(T) could also be distinguished from its close phylogenetic relatives by cultural and physiological characteristics. Therefore, it is proposed that strain NEAU-JM2(T) represents a novel species of the genus Micromonospora, for which the name Micromonospora vulcania sp. nov. is proposed. The type strain is NEAU-JM2(T) (=CGMCC 4.7144(T) = DSM 46711(T)).
