A novel actinobacterium, designated strain NEAU-GS50, was isolated from soil collected from Mount Song and characterized by using a polyphasic approach. Phylogenetic analysis based on the 16S rRNA gene sequence indicated that the organism should be assigned to the genus Promicromonospora and that it forms a monophyletic clade with its closest relatives Promicromonospora umidemergens JCM 17975 (98.94 % 16S rRNA gene sequence similarity), Promicromonospora alba 1C-HV12 (98.82 %) and Promicromonospora kermanensis DSM45485 (98.68 %). Similarly, chemotaxonomic data including major menaquinones, fatty acid compositions and polar lipid profiles, also supported the placement of strain NEAU-GS50 in the genus Promicromonospora. However, DNA-DNA relatedness, physiological and biochemical data showed that strain NEAU-GS50 could be distinguished from its closest relatives. Therefore, strain NEAU-GS50 represents a novel species of the genus Promicromonospora, for which the name Promicromonospora soli sp. nov. is proposed, with strain NEAU-GS50 (CGMCC4.7398=DSM 104515) as the type strain.
从嵩山采集的土壤中分离出一株新型放线菌，命名为NEAU-GS50菌株，并采用多相分类法对其进行了鉴定。基于16S rRNA基因序列的系统发育分析表明，该菌株应归属于原小单孢菌属，并且与最接近的亲缘种淹水原小单孢菌JCM 17975（16S rRNA基因序列相似性为98.94%）、白色原小单孢菌1C-HV12（98.82%）和克尔曼原小单孢菌DSM45485（98.68%）形成一个单系分支。同样，包括主要甲基萘醌、脂肪酸组成和极性脂质谱在内的化学分类数据也支持将NEAU-GS50菌株归属于原小单孢菌属。然而，DNA-DNA杂交、生理生化数据表明，NEAU-GS50菌株可与其最接近的亲缘种区分开来。因此，NEAU-GS50菌株代表了原小单孢菌属的一个新物种，为此提出原小单孢菌新种的名称为土壤原小单孢菌（Promicromonospora soli sp. nov.），以NEAU-GS50菌株（CGMCC4.7398 = DSM 104515）作为模式菌株。
