Abstract

A novel Gram-negative, slightly halophilic, catalase-positive, oxidase-negative, obligately aerobic, non-sporulating rod-shaped bacterium, designated strain JSM 078169, was isolated from a sea urchin () collected from the South China Sea. Growth occurred with 1–20 % (w/v) total salts (optimum, 3–5 %), at pH 6.0–10.5 (optimum, pH 7.5) and at 4–40 °C (optimum, 25–30 °C). The major cellular fatty acids were C 7, C and C 3-OH. The predominant respiratory quinone was Q-9 and the genomic DNA G+C content was 55.8 mol%. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain JSM 078169 should be assigned to the genus . The sequence similarities between the isolate and the type strains of members of the genus were in the range 92.4–97.0 %. The combination of phylogenetic analysis, DNA–DNA relatedness, phenotypic characteristics and chemotaxonomic data supported the view that strain JSM 078169 represents a novel species of the genus , for which the name sp. nov. is proposed, with JSM 078169 (=CCTCC AB 208031=DSM 21076=KCTC 22279) as the type strain.
