A Gram-stain-positive actinobacterium, designated strain GSSD-12T, was isolated from an alpine wetland soil. blast search of the full-length 16S rRNA gene sequence of GSSD-12T indicated it represented a member of the genus
Streptomyces
, and displayed highest similarity with
Streptomyces scopuliridis
NRRL B-24574T (99.2 %) and less than 98.6 % similarity with other species of the genus
Streptomyces
with validly published names. Phylogenetic analysis based on 16S rRNA gene sequences indicated that GSSD-12T was closely related to
S. scopuliridis
NRRL B-24574T,
Streptomyces odonnellii
NRRL B-24891T and
Streptomyces lushanensis
NRRL B-24994T. 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-12T was also distinctly differentiated from them by morphological, physiological and biochemical characteristics. Therefore, strain GSSD-12T(=CICC 11051T=JCM 33019T) represents a novel species of the genus
Streptomyces
, for which the name Streptomyces paludis sp. nov. is proposed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
