Streptomyces spiramenti sp. nov., isolated from a deep-sea microbial mat

Strain 5675061 T was isolated from a deep-sea microbial mat near hydrothermal vents within the Axial Seamount caldera on the Juan de Fuca Ridge (NE Pacific Ocean) and was taxonomically evaluated using a polyphasic approach. Morphological and chemotaxonomic properties are consistent with characteristics of the genus Streptomyces : aerobic Gram-stain-positive filaments that form spores, l,l -diaminopimelic acid in whole-cell hydrolysates, and iso -C 16:0 as the major fatty acid. Phylogenetic analysis, genomic, and biochemical comparisons show close evolutionary relatedness to Streptomyces lonarensis NCL716 T , S. bohaiensis 11A07 T , and S. otsuchiensis OTB305 T but genomic relatedness indices identify strain 5675061 T as a distinct species. Based on a polyphasic characterization, identifying differences in genomic and taxonomic data, strain 5675061 T represents a novel species, for which the name Streptomyces spiramenti sp. nov. is proposed. The type strain is 5675061 T (=LMG 31896 T = DSM 111793 T ).
