Strain W-BA2T grew optimally at 25 °C, at pH 7.0–8.0 and in the presence of approximately 2.0–3.0 % (w/v) NaCl. Phylogenetic trees based on 16S rRNA gene sequences revealed that strain W-BA2T fell within the clade comprising the type strains of species of the genus Sulfitobacter , clustering coherently with the type strains of Sulfitobacter donghicola and Sulfitobacter guttiformis showing sequence similarity values of 98.0–98.1 %. Sequence similarities to the type strains of the other species of the genus Sulfitobacter were 96.0–97.4 %. Strain W-BA2T contained Q-10 as the predominant ubiquinone and C18 : 1ω7c as the major fatty acid. The major polar lipids of strain W-BA2T were phosphatidylcholine, phosphatidylglycerol, phosphatidylethanolamine, one unidentified aminolipid and one unidentified lipid. The DNA G+C content of strain W-BA2T was 55.0 mol% and its DNA–DNA relatedness values with the type strains of Sulfitobacter donghicola , Sulfitobacter guttiformis and Sulfitobacter mediterraneus were 16–23 %. The differential phenotypic properties, together with the phylogenetic and genetic distinctiveness, revealed that strain W-BA2T is separated from other species of the genus Sulfitobacter . On the basis of the data presented, strain W-BA2T is considered to represent a novel species of the genus Sulfitobacter , for which the name Sulfitobacter undariae sp. nov. is proposed. The type strain is W-BA2T ( = KCTC 42200T = NBRC 110523T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.000156
