Abstract:
A novel actinobacterium, designated strain NEAU-GS50T, 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 17975T (98.94 % 16S rRNA gene sequence similarity), Promicromonospora alba 1C-HV12T (98.82 %) and Promicromonospora kermanensis DSM45485T (98.68 %). Similarly, chemotaxonomic data including major menaquinones, fatty acid compositions and polar lipid profiles, also supported the placement of strain NEAU-GS50T in the genus Promicromonospora. However, DNA-DNA relatedness, physiological and biochemical data showed that strain NEAU-GS50T could be distinguished from its closest relatives. Therefore, strain NEAU-GS50T represents a novel species of the genus Promicromonospora, for which the name Promicromonospora soli sp. nov. is proposed, with strain NEAU-GS50T (CGMCC4.7398T=DSM 104515T) as the type strain.
