Phylogenetic analysis of 16S rRNA gene sequences revealed that strain KHS02T formed a monophyletic clade with Pseudahrensia aquimaris HDW-32T, with which it had the highest sequence similarity (98.67 %). Strain KHS02T grew optimally at pH 7 with 2 % (w/v) NaCl at 25 °C on marine broth 2216, but could not grow without Na+. The predominant isoprenoid quinone was ubiquinone-10 (Q-10). The major fatty acids (>10 % of the total) were summed feature 8 (C18 : 1ω6c and/or C18 : 1ω7c) and 11-methyl C18 : 1ω7c. The polar lipids of strain KHS02T comprised phosphatidylcholine, phosphatidylglycerol, phosphatidylethanolamine, two unidentified aminolipids, an unidentified phospholipid and an unidentified lipid. The genomic DNA G+C content was 58.6 mol%. DNA–DNA hybridization showed that the isolate shared 16.2 ± 1.3 % (reciprocal, 15.7 ± 2.8 %) genomic relatedness with the type strain of the closest species. In conclusion, this isolate is suggested to represent a novel species of the genus Pseudahrensia, for which the name Pseudahrensia todarodis is proposed. The type strain is KHS02T ( = KACC 18257T = JCM 30419T)., language=, type=
