Abstract
A novel Gram-stain-positive actinomycete, designated MB-PO13(T), was isolated from a tunicate (Molgula manhattensis) collected in Tokyo Bay, Japan, and its taxonomic position was studied by a polyphasic approach. Phylogenetic analysis based on 16S rRNA gene sequence comparisons revealed that strain MB-PO13(T) was closely related to Streptomyces graminisoli JR-12(T) (99.72% 16S rRNA gene sequence similarity) and Streptomyces shenzhenensis 172115(T) (99.23%). The strain contained LL-diaminopimelic acid in the whole-cell hydrolysate. The predominant menaquinones were MK-9(H8) and MK-9(H6) and the major fatty acids were anteiso-C15:0, iso-C16:0, iso-C14:0 and C16:0. These data supported the affiliation of the novel strain to the genus Streptomyces. Meanwhile, results of DNA-DNA hybridization and physiological and biochemical tests indicated that strain MB-PO13(T) was distinguished from known Streptomyces type strains. Therefore, strain MB-PO13(T) represents a novel species of the genus Streptomyces for which the name Streptomyces hyaluromycini sp. nov. is proposed; the type strain is MB-PO13(T) (=NBRC 110483(T) =DSM 100105(T)).Entities:
