Cells of strain FA028T were rod-shaped, 1–3 μm in length and 0.5 μm in width. The strain was able to grow at 13–37 °C, at pH 7.0–9.5 and in the presence of 1.0–4.0 % (w/v) NaCl. Optimal growth was observed at 28 °C, with 3.0 % NaCl and at pH 7.5–8.0. Nitrate was not reduced. The G+C content of the DNA was 43.4 mol%. The isoprenoid quinone was Q-9 and the main cellular fatty acids (>10 %) were C16 : 0, C16 : 1ω9c and iso-C15 : 0 2-OH/C16 : 1ω7c. The major polar lipids in strain FA028T were phosphatidylglycerol, phosphatidylethanolamine and diphosphatidylglycerol; phospholipid was present in moderate to minor amounts in the polar lipid profile. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain FA028T was affiliated with the phylum Proteobacteria. 16S rRNA gene sequence comparisons showed that this isolate is unique, sharing < 93 % similarity with species of the families Alteromonadaceae and Oceanospirillaceae. On the basis of the phenotypic and phylogenetic data, strain FA028T should be classified as representing a novel species of a new genus within the family Alteromonadaceae, for which the name Alkalimarinus sediminis gen. nov., sp. nov. is proposed. The type strain of Alkalimarinus sediminis is FA028T ( = CICC 10906T = KCTC 42258T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.000446
