Strain JDTF-79T grew optimally at 25 °C and in the presence of 2.0 % (w/v) NaCl. Phylogenetic trees based on 16S rRNA gene sequences showed that strain JDTF-79T fell within the clade comprising the type strains of species of the genus Tenacibaculum , clustering with the type strains of Tenacibaculum dicentrarchi , Tenacibaculum ovolyticum , ‘ Tenacibaculum haliotis’ and Tenacibaculum soleae . The novel strain exhibited highest 16S rRNA gene sequence similarity (98.3 %) to the type strain of T. dicentrarchi and sequence similarities of 93.5–96.9 % to the type strains of the other species of the genus Tenacibaculum . Strain JDTF-79T contained MK-6 as the predominant menaquinone and anteiso-C15 : 0, iso-C15 : 0 3-OH and iso-C15 : 0 as the major fatty acids. The major polar lipids of strain JDTF-79T were phosphatidylethanolamine, one unidentified lipid and one unidentified aminophospholipid. The DNA G+C content of strain JDTF-79T was 30.3 mol%. Strain JDTF-79T had a mean DNA–DNA relatedness value of 19 % with the type strain of T. dicentrarchi . The differential phenotypic properties, together with the phylogenetic and genetic data, revealed that strain JDTF-79T is separated from other recognized species of the genus Tenacibaculum . On the basis of the data presented, strain JDTF-79T is considered to represent a novel species of the genus Tenacibaculum , for which the name Tenacibaculum aestuariivivum sp. nov. is proposed. The type strain is JDTF-79T (=KCTC 52980T=NBRC 112903T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.002343
