A Gram-stain-negative, elongated rod-shaped, yellow-pigmented, aerobic bacterial strain, designated WJ-1T, was isolated from coastal seawater in Xiamen, Fujian province, China. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain WJ-1T fell within the genus Tenacibaculum and was most closely associated with Tenacibaculum aestuarii SMK-4T (96.7 % 16S rRNA gene sequence similarity); lower similarities were shown to other members of the genus Tenacibaculum (<96.2 %). The strain formed a distinct lineage with Tenacibaculum litopenaei B-IT (96.0 %), Tenacibaculum geojense YCS-6T (94.5 %) and Tenacibaculum jejuense CNURIC 013T (95.4 %). Growth was observed at temperatures from 16 to 38 °C, at salinities from 2 to 4 % and at pH 6–9. The major fatty acids were summed feature 3 (C16 : 1ω6c and/or C16 : 1ω7c), iso-C17 : 0 3-OH, iso-C15 : 0 and iso-C15 : 0 3-OH. The DNA G+C content of strain WJ-1T was 33.2 mol% and the major respiratory quinone was menaquinone-6 (MK-6). Differential phenotypic properties and phylogenetic distinctiveness in this study distinguished strain WJ-1T from all other members of the genus Tenacibaculum . According to the morphology, physiology, fatty acid composition and 16S rRNA gene sequence data, strain WJ-1T represents a novel species of the genus Tenacibaculum , for which the name Tenacibaculum xiamenense sp. nov. is proposed. The type strain is WJ-1T ( = CGMCC 1.12378T = LMG 27422T).
