Abstract

A novel bacterium, designated strain JHSY0214, was isolated from the gut of a Korean limpet, . Cells of strain JHSY0214 were Gram-stain-negative, strictly aerobic, yellow-pigmented, non-spore-forming, non-motile and showed a rod–coccus growth cycle. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the strain belonged to the genus , and was most closely related to KCTC 12764 (98.71 %). Strain JHSY0214 had two fluoroquinolone-resistance genes and seven multidrug-resistance efflux pump genes, but did not have beta-lactamase genes and zinc resistance genes compared with KCTC 12764. Strain JHSY0214 grew optimally at 30 °C, pH 7.0 and in the presence of 2 % (w/v) NaCl. The predominant cellular fatty acids of strain JHSY0214 were summed feature 8 (C 6 and/or C 7; 41.2 %), summed feature 3 (C 7 and/or C 6; 21 %) and C (18.9 %). The major isoprenoid quinone was ubiquinone-10. The major polar lipids were sphingoglycolipid and phosphatidylethanolamine. The genomic DNA G+C content was 52.8 mol%. Based on phylogenetic, genotypic and phenotypic data, strain JHSY0214 represents a novel species of the genus , for which the name is proposed. The type strain is JHSY0214 (=KCTC 82387=DSM 112279).
