abstract= A Gram-staining-negative, aerobic, non-flagellated, non-gliding and ring-like or horseshoe-shaped bacterial strain, designated HD-17T, was isolated from a tidal flat sediment in the Korean peninsula. Strain HD-17T grew optimally at pH 7.0–8.0, at 25 °C and in the presence of 2.0 % (w/v) NaCl. Phylogenetic analyses based on 16S rRNA gene sequences revealed that strain HD-17T fell within the clade comprising species of the genus Cyclobacterium . Strain HD-17T exhibited 16S rRNA gene sequence similarity values of 93.8–98.8 % to the type strains of species of the genus Cyclobacterium . Strain HD-17T contained MK-7 as the predominant menaquinone and iso-C15 : 0, summed feature 3 (C16 : 1ω6c and/or C16 : 1ω7c), anteiso-C15 : 0 and iso-C15 : 1 G as the major fatty acids. The major polar lipids of strain HD-17T were phosphatidylcholine, phosphatidylethanolamine and two unidentified lipids. The DNA G+C content of strain HD-17T was 43.8 mol% and its DNA–DNA relatedness values with Cyclobacterium amurskyense KCTC 12363T, Cyclobacterium qasimii KCTC 23011T and Cyclobacterium marinum KCTC 2917T were 10.4, 7.6 and 5.3 %, respectively. The phylogenetic and genetic distinctiveness and several differentiating phenotypic properties revealed that strain HD-17T was separate from other species of the genus Cyclobacterium . On the basis of the data presented, strain HD-17T represents a novel species of the genus Cyclobacterium , for which the name Cyclobacterium caenipelagi sp. nov. is proposed. The type strain is HD-17T ( = KCTC 32178T = CCUG 63247T). An emended description of the genus Cyclobacterium is also provided.,
