Abstract

A Gram-stain-positive actinobacterium, designated strain GSSD-12, was isolated from an alpine wetland soil. search of the full-length 16S rRNA gene sequence of GSSD-12 indicated it represented a member of the genus , and displayed highest similarity with NRRL B-24574 (99.2 %) and less than 98.6 % similarity with other species of the genus with validly published names. Phylogenetic analysis based on 16S rRNA gene sequences indicated that GSSD-12 was closely related to NRRL B-24574, NRRL B-24891 and NRRL B-24994. However, the digital DNA–DNA hybridization value, the average nucleotide identity value and the multilocus sequence analysis evolutionary distance between this strain and its closest relatives indicated that it represented a distinct species. Furthermore, GSSD-12 was also distinctly differentiated from them by morphological, physiological and biochemical characteristics. Therefore, strain GSSD-12(=CICC 11051=JCM 33019) represents a novel species of the genus , for which the name sp. nov. is proposed.
