Strain HDW-15T grew optimally at pH 7.0–8.0, at 25 °C and in the presence of 2 % (w/v) NaCl. Phylogenetic analyses based on 16S rRNA gene sequences revealed that strain HDW-15T fell within the clade comprising Marinomonas species, joining the type strain of Marinomonas arctica , with which it exhibited highest 16S rRNA gene sequence similarity (97.7 %). The 16S rRNA gene sequence similarity values between strain HDW-15T and the type strains of other Marinomonas species were in the range 93.7–97.2 %. Mean DNA–DNA relatedness values between strain HDW-15T and the type strains of M. arctica , Marinomonas polaris and Marinomonas pontica were 5.0–9.9 %. The DNA G+C content of the isolate was 48.7 mol%. Strain HDW-15T contained Q-8 as the predominant ubiquinone and C18 : 1ω7c, summed feature 3 (C16 : 1ω7c and/or iso-C15 : 0 2-OH) and C16 : 0 as the major fatty acids. The major polar lipids found in strain HDW-15T were phosphatidylglycerol and phosphatidylethanolamine. Differential phenotypic properties, together with phylogenetic and genetic distinctiveness, showed that strain HDW-15T can be differentiated from other Marinomonas species. On the basis of the data presented, strain HDW-15T is considered to represent a novel species of the genus Marinomonas , for which the name Marinomonas hwangdonensis sp. nov. is proposed. The type strain is HDW-15T ( = KCTC 23661T = CCUG 61321T). %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.036582-0
