A novel actinobacterium, designated ASO4wetT, was isolated from the unidentified sponge (SO4) in the deep sea collected of the North Atlantic Ocean. Study of 16S rRNA gene sequences indicated that strain ASO4wetT is a member of the genus Streptomyces and showed the closest similarities to Streptomyces karpasiensis K413T (98.87 %), Streptomyces glycovorans YIM M 10366T (98.38 %), and Streptomyces abyssalis YIM M 10400T (97.53 %). Strain ASO4wetT contained MK-9(H8) as the predominant menaquinone and the major fatty acids are iso-C16:0, anteiso-C15:0, and iso-C15:0. Polyphasic taxonomy was carried out between strain ASO4wetT and its phylogenetically closely related Streptomyces strains, which further elucidated their relatedness and revealed that strain ASO4wetT could be distinguished from currently known Streptomyces species. Strain ASO4wetT clearly represents a novel species in genus Streptomyces. We propose the name Streptomyces bathyalis sp. nov., with the type strain ASO4wetT (= DSM 106605T = NCCB 100657T). Analysis of the whole-genome sequence of S. bathyalis revealed that genome size is 7,377,472 bp with 6332 coding sequences.
