Streptomyces cupreus sp. nov., an antimicrobial producing actinobacterium isolated from Himalayan soil. Arch Microbiol. 2021 Jan 07;: Authors: Maiti PK, Mandal S Abstract A novel actinobacterium, designated Streptomyces sp strain PSKA01T, was isolated from a soil sample of Kashmir Himalaya, India (latitude:34˚-01'N; longitude:74˚-47'E; altitude: 5328 ft). The taxonomic position of this strain was revealed by a polyphasic approach. Comparative analysis of the 16S rRNA gene sequences indicated that PSKA01T was closely related to the members of the genus Streptomyces, with the highest similarity to Streptomyces venetus CMU-AB225T (99.3%), Streptomyces levis NBRC 15423 T (99.3%), Streptomyces misionensis DSM 40306 T (99.2%), Streptomyces carpinensis NRRL B-16921 T (99.2%), Streptomyces purpurascens NBRC 13077 T (99.2%), and Streptomyces phaeoluteichromatogenes NRRL 5799 T (99.2%). A phylogenomic tree based on genome sequences of the isolated strains, conferred by Type Strain Genome Server (TYGS), separated them from rest of the Streptomyces. The cell wall contained LL-diaminopimelic acid and the whole-cell hydrolysates were xylose and rhamnose. Major fatty acid methyl esters (FAME) were observed as 16:0 iso and 17:0 anteiso. In addition to the differences in phenotypic characters, the average nucleotide identity (ANI), average amino acid identity (AAI), digital DNA-DNA hybridization (dDDH) values, tetranucleotide frequency correla...
