Strain WS2-14T grew optimally at 28 °C and pH 7.0–7.5, and was able to tolerate salt concentrations of 0.5–6.0 % (w/v) NaCl. Strain WS2-14T was characterized chemotaxonomically as possessing menaquinone-6 (MK-6) as the major respiratory quinone, as well as iso-C13 : 0, iso-C15 : 0 3-OH and iso-C15 : 0 as the predominant fatty acids. The DNA G+C content of strain WS2-14T was 31.2 mol%. The major polar lipids were phosphatidylethanolamine, one unidentified phospholipid, one unidentified aminolipid and three unidentified lipids. Phylogenetic analyses based on 16S rRNA gene sequences revealed that strain WS2-14T was phylogenetically related to members of the genus Polaribacter and was closely related to Polaribacter haliotis , Polaribacter atrinae and Polaribacter sejongensis with 97.7, 97.4 and 97.0 % sequence similarities, respectively. On the basis of its phenotypic and chemotaxonomic properties, as well as phylogenetic analyses, strain WS2-14T was considered to represent a novel species of the genus Polaribacter , for which the name Polaribacter tangerinus sp. nov. is proposed. The type strain is WS2-14T (=KCTC 52275T=MCCC 1H00163T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.002369
