Cells of CY02T were aerobic, coccus or short rods. Growth occurred at 5–42 °C (optimum, 35 °C), pH 6–10 (optimum, 8.0) and 0.5–9.0 % NaCl (optimum, 1.5–3.0 %). Phylogenetic analysis of 16S rRNA gene sequences revealed that CY02T was a member of the family Rhodobacteraceae and exhibited less than 95 % sequence similarities with the closely related type strains of the family Rhodobacteraceae . The genomic DNA G+C content of CY02T was 57.5 mol%. The major respiratory quinone was ubiquinone-10 (Q-10). The polar lipids consisted of phosphatidylcholine, phosphatidylglycerol, phosphatidylethanolamine, diphosphatidylglycerol, three unidentified lipids, one unidentified phospholipid and one unidentified aminolipid. The predominant cellular fatty acids were C18 : 1ω7c (57.6 %), 11-methyl C18 : 1ω7c (22.8 %) and C16 : 0 (10.6 %). Based on the results of morphological, physiological, biochemical, chemotaxonomic, genotypic and phylogenetic analyses, strain CY02T represents a novel species of a novel genus of the family Rhodobacteraceae , for which the name Neptunicoccus sediminis gen. nov., sp. nov. is proposed. The type strain of Neptunicoccus sediminis is CY02T (=CCTCC AB 2015430T=KCTC 42985T=NBRC 111872T=MCCC 1K03518)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.002728
