An aerobic, Gram-negative, coccoid to short rod-shaped and non-flagellated marine bacterial strain S354ᵀwas isolated from seawater of Micronesia. The strain was capable to degrade agar-forming slight depression into agar plate. Growth occurred at a temperature range of 12–44 °C, a pH range of 5–9, and a salinity range of 1–7 % (w/v) NaCl. Phylogenetic analyses based on 16S rRNA gene sequences suggested that S354ᵀbelongs to the family Flammeovirgaceae. The novel strain was most closely related to Limibacter armeniacum YM 11-185ᵀwith similarity of 92.5 %. The DNA G+C content was 43.8 mol%. The major fatty acids (>10 %) were iso-C₁₅:₀and C₁₆:₁ω5c. The predominant isoprenoid quinone was determined to be MK-7. Polar lipid profile of S354ᵀconsisted of phosphatidylethanolamine, unknown polar lipid, and unknown glycolipids. Based on the phenotypic, phylogenetic, biochemical, and physiological tests conducted in this study, S354ᵀis proposed to represent a type strain of a novel genus and species. The 16S rRNA gene sequence of S354ᵀis registered in GenBank under the accession number JQ639084. The type of strain Algivirga pacifica gen. nov., sp. nov. is S354ᵀ(=KCCM 90107ᵀ=JCM 18326ᵀ).
