The isolates grew at 10–37 °C, at pH 5.0–9.0 and in NaCl concentrations of 0.5–15 % (w/v; optimum, 3.0–6.0 %). Sequence analysis of the 16S rRNA indicated that the isolates belong to the genus Marinobacter and are most closely related to Marinobacter sediminum R65T (98.3 %), followed by Marinobacter lipolyticus SM19T, Marinobacter salsuginis SD-14BT and Marinobacter similis A3d10T. The overall 16S rRNA gene sequence similarity with these species was 97.9 %, but Hb8T and Hb20 showed 100 % sequence similarity with each other. DNA–DNA relatedness values of H8T and Hb20 suggested that these isolates represent a single species, while DNA–DNA relatedness values of the two novel isolates with M. sediminum DSM 27079T and M. similis DSM 15400T were only 21.3 and 22.9 %, respectively. The major fatty acids present in strain Hb8T were identified as C16 : 0, C16 : 1ω9c, C18 : 1ω9c, C18 : 0 3-OH and summed feature 3 (C16 : 1ω6c and/or C16 : 1ω7c). Ubiquinone-9 was the main respiratory quinone in both the novel strains. The polar lipids found to be present included diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, four unidentified phospholipids and five unidentified lipids. The genomic DNA G+C content of Hb8T and Hb20 was 54.5 mol%. Polyphasic analysis indicated that the two isolates are representatives of a novel species of the genus Marinobacte , for which the name Marinobacter salinus sp. nov. is proposed. The type strain is Hb8T (=KCTC 52255T=JCM 31416T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.001587
