Abstract

A slightly curved-rod-shaped, pink-pigmented, Gram-stain-negative, aerobic bacterial strain with gliding motility, designated SK-8, was isolated from coastal surface water of Misaki, Japan. Phylogenetic trees generated using 16S rRNA gene sequences revealed that strain SK-8 belonged to the genus and showed 96.0 % sequence similarity to the type strain of the most closely related species, DY53. The novel isolate was phenotypically and physiologically different from previously described strains. The major cellular fatty acids were iso-C G, iso-C and iso-C 3-OH. Major polar lipids were phosphatidylethanolamine, two aminophospholipids and an unidentified phospholipid. The DNA G+C content was 39.1 mol% and MK-7 was the only predominant isoprenoid quinone. On the basis of this taxonomic study employing a polyphasic approach, it was suggested that strain SK-8 represents a novel species of the genus , with the newly proposed name sp. nov. The type strain is SK-8 ( = NBRC 110216 = KCTC 32969).
