A Gram-staining-negative, non-spore-forming, aerobic, non-flagellated, non-gliding, rod-shaped bacterium, designated strain T-y7T, was isolated from seawater collected in an oyster farm in the South Sea, South Korea, and subjected to a polyphasic study. Strain T-y7T grew optimally at 256C, at pH 7.0-8.0 and in the presence of 2% (w/v) NaCl. In phylogenetic analyses based on 16S rRNA gene sequences, strain T-y7T fell within a clade comprising Bizionia species. It formed a coherent cluster with the type strains of Bizionia algoritergicola, B. argentinensis, B. echini and B. myxarmorum, with which it exhibited 16S rRNA gene sequence similarities of 97.4-98.9% and mean DNA-DNA relatedness values of 11-27%. Strain T-y7T had MK-6 as its predominant menaquinone and iso-C15: 1 G, summed feature 3 (C16: 1v7c and/or iso-C15: 0 2-OH), iso-C15: 0 and iso-C17: 0 3-OH as its major fatty acids. The major polar lipids were phosphatidylethanolamine, one unidentified aminolipid and one unidentified lipid. The genomic DNA G+C content was 37.1 mol%. Its phylogenetic and genetic distinctiveness and differential phenotypicproperties revealed that strain T-y7T does not belong to any established Bizionia species. On the basis of the data presented, strain T-y7T is considered to represent a novel species of the genus Bizionia, for which the name Bizionia hallyeonensis sp. nov. is proposed. The type strain is T-y7T (5KCTC 23881T 5CCUG 62110T).
