Cells of strain HSLHS2T were found to be aerobic, Gram-stain-negative, non-flagellated, non-motile, short rods. Oxidase- and catalase-positive. Growth was observed at 5–40 °C (optimum, 35 °C), at pH 6.0–10.0 (optimum pH 8.0) and in 0–10 % NaCl (optimum 2 %, w/v). Strain HSLHS2T shared highest 16S rRNA gene sequence similarity with Celeribacter halophilus ZXM137T (95.4 %), but formed a distinct phyletic lineage and coherent phylogenetic cluster associated with Marivivens donghaensis AM-4T (95.1 %). The dominant fatty acids were summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c) and C16 : 0. The respiratory quinone was determined to be Q-10. The polar lipids comprised phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol, three unidentified aminolipids, four unidentified lipids, five unidentified phospholipids. The DNA G+C contents was 54.6 mol%. The combined genotypic and phenotypic data indicated that strain HSLHS2T represents a novel species of the genus Marivivens , for which the name Marivivens niveibacter sp. nov. is proposed. The type strain is HSLHS2T (=KCTC 52588T=MCCC 1A06712T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.002544
