Abstract

A yellow, rod-shaped, Gram-reaction-negative bacterial strain, designated LPB0076, was isolated from a Pacific oyster. Results of 16S rRNA gene sequence analyses indicated that the strain represented a member of the genus . It had the highest sequence similarity to the type strains of (97.6 %) and (97.0 %), and its similarities with all other species of the genus were below 97.0 %. Its genome size (3.02 Mb), DNA G+C content (36.0 mol%), predominant cellular fatty acids (anteiso-C, iso-C and Cω7 and/or Cω6), and major polar lipid (phosphatidylethanolamine) were similar to those described previously for members of the genus . In contrast, a number of phenotypic characteristics, including the inability to grow microaerophilically, absence of flexirubin-type pigments and gliding motility and differences in enzymatic reactions, clearly distinguished LPB0076 from other species of the genus . The polyphasic data presented in this study indicate that this isolate should be classified as representing a novel species of the genus . The name sp. nov. is therefore proposed for the isolate, with the type strain being LPB0076 (=KACC 18706=JCM 31219).
