Strain R18H21T grew at 4–40 °C (optimum 25 °C), at pH 6.3–9.2 (optimum 7.5–8.5) and in 0.5–6 % (w/v) NaCl (optimum 2 %). Phylogenetic analyses based on 16S rRNA gene sequences showed that strain R18H21T belonged to the genus Arenibacter , with the highest similarity to two type strains, Arenibacter latericius KMM 426T (96.6 %) and Arenibacter certesii KMM 3941T (96.6 %), and lower similarities (95.2–95.9 %) to five other members of the genus Arenibacter . The major fatty acids were iso-C17 : 0 3-OH, Summed Feature 3 (C16 : 1 ω6c and/or C16 : 1 ω7c), iso-C15 : 0, iso-C15 : 1 G. The major polar lipids were phosphatidylethanolamine, an unidentified aminolipid and an unidentified phospholipid. The respiratory quinone of strain R18H21T was menaquinone-6. The DNA G+C content was 40.0 mol%. Based on phylogenetic, physiological and chemotaxonomic features, strain R18H21T has been classified as a novel species in the genus Arenibacter , for which the name Arenibacter antarcticus sp. nov. is proposed. The type strain of the novel species is R18H21T (=GDMCC 1.1159T=KCTC 52924T).", }
