Optimal growth of strain IMCC3317T was observed at 20 °C, pH 8.0 and in the presence of 2–3 % NaCl. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain IMCC3317T belonged to the genus Kordia and was closely related to Kordia algicida OT-1T (96.7 % sequence similarity) and Kordia periserrulae IMCC1412T (96.1 % sequence similarity). The major fatty acids were 10-methyl C16 : 0 and/or iso-C16 : 1ω9c, iso-C17 : 0 3-OH, iso-C15 : 0 and anteiso-C15 : 0. The G+C content of the genomic DNA was 35.1 mol%. The strain contained menaquinone-6 (MK-6) as the respiratory quinone. The polar lipids detected in the strain were phosphatidylethanolamine and unknown aminophospholipids, aminolipids and polar lipids. On the basis of phylogenetic distinction and differential phenotypic characteristics, it is suggested that strain IMCC3317T ( = KCTC 32292T = NBRC 109401T) be assigned to the genus Kordia as the type strain of a novel species, for which the name Kordia antarctica sp. nov. is proposed., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.052738-0
