Cells were Gram-stain-negative, facultative anaerobic, non-motile and rod-shaped. The temperature, pH and NaCl ranges for growth were determined as 4–40 °C, pH 6.5–9.5 and 0.5–15.0 % (w/v), respectively. Phylogenetic analysis based on the 16S rRNA gene sequences indicated that strain HJR7T belongs to the genus Marinobacter in the family Alteromonadaceae . The most closely related species were Marinobacter aromaticivorans (97.6 % 16S rRNA gene sequence similarity) and Marinobacter maritimus (97.3 % similarity). Ubiquinone 9 (Q-9) was the only respiratory quinone detected in strain HJR7T. The major fatty acids of strain HJR7T were C12 : 0, C16 : 0, C16 : 0 N alcohol, C18 : 1ω9c and C18 : 3ω6, 9, 12c. The major polar lipids were phosphatidylglycerol, phosphatidylethanolamine, and an unidentified phospholipid. The DNA G+C content of strain HJR7T was 53.7 mol%. On the basis of phylogenetic, genotypic, phenotypic, and chemotaxonomic analyses, strain HJR7T represents a novel species within the genus Marinobacter , for which the name Marinobacter salexigens sp. nov. is proposed. The type strain is HJR7T (=KCTC 52545T=MCCC 1H00176T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.002337
