Abstract

A Gram-stain-negative, non-motile, non-spore-forming and short rod- or rod-shaped bacterial strain, designated 22-5, was isolated from a bluespotted cornetfish, , and subjected to taxonomic study. Strain 22-5 grew optimally at 30 °C and in the presence of 2–5 % (w/v) NaCl. Phylogenetic analyses based on 16S rRNA gene sequences revealed that strain 22-5 belonged to the genus and joined the cluster comprising DD-R11 and ATCC 21588, with which strain 22-5 exhibited 97.4 and 96.9 % 16S rRNA gene sequence similarity, respectively. Strain 22-5 exhibited 94.0–96.6 % 16S rRNA gene sequence similarity with the other type strains of species of the genus . Strain 22-5 contained Q-10 as the predominant menaquinone and C 7 as the predominant fatty acid. In this study, . KCTC 22688 also contained Q-10 as the predominant isoprenoid quinone. The DNA G+C content of strain 22-5 was 63.6 mol%. Strain 22-5 exhibited 44 and 32 % DNA–DNA relatedness to . KACC 11518 and . KCTC 22688, respectively. On the basis of phenotypic, phylogenetic and genetic data, strain 22-5 is considered to represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is 22-5 (=KCTC 22803 =CCUG 58401).
