Abstract
A novel actinobacterium, designated ASO4wet T , 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 ASO4wet T is a member of the genus Streptomyces and showed the closest similarities to Streptomyces karpasiensis K413 T (98.87 %), Streptomyces glycovorans YIM M 10366 T (98.38 %), and Streptomyces abyssalis YIM M 10400 T (97.53 %). Strain ASO4wet T contained MK-9(H8) as the predominant menaquinone and the major fatty acids are iso-C 16:0 , anteiso-C 15:0 , and iso-C 15:0 . Polyphasic taxonomy was carried out between strain ASO4wet T and its phylogenetically closely related Streptomyces strains, which further elucidated their relatedness and revealed that strain ASO4wet T could be distinguished from currently known Streptomyces species. Strain ASO4wet T clearly represents a novel species in genus Streptomyces . We propose the name Streptomyces bathyalis sp. nov., with the type strain ASO4wet T (= DSM 106605 T = NCCB 100657 T ). Analysis of the whole-genome sequence of S. bathyalis revealed that genome size is 7,377,472 bp with 6332 coding sequences.
