Cells of strain P-1 km-3T were Gram-stain-negative, aerobic, catalase- and oxidase-positive, dimorphic rods with a single polar prostheca or flagellum. The strain hydrolysed gelatin and grew at 6–40 °C (optimum, 30 °C) and with 0.5–12 % (w/v) NaCl (optimum, 2 %). Phylogenetic analysis of the 16S rRNA gene sequences revealed that strain P-1 km-3T belonged to the family Hyphomonadaceae in the class Alphaproteobacteria and represented a separate lineage, located between the genera Oceanicaulis and Woodsholea . Sequence similarities of strain P-1 km-3T with type strains of species of the genera Oceanicaulis and Woodsholea were 93.2–93.9 %. The predominant cellular fatty acids in strain P-1 km-3T were C18 : 1ω7c, C18 : 0, 11-methyl C18 : 1ω7c, C17 : 0 and C19 : 0 cyclo ω8c. The major respiratory quinone of strain P-1 km-3T was Q-10. The polar lipids of strain P-1 km-3T comprised glucuronopyranosyldiglyceride (GUDG), monoglycosyldiglyceride (MGDG), sulfo-quinovosyl diacylglycerol (SQDG), phosphatidylglycerol (PG), an unidentified phospholipid (PL) and an unidentified lipid (L). The genomic DNA G+C content of strain P-1 km-3T was 66.0 mol%. On the basis of the polyphasic data presented in this study, strain P-1 km-3T is proposed to represent a novel species in a new genus, Marinicauda pacifica gen. nov., sp. nov., within the family Hyphomonadaceae . The type strain of the type species is P-1 km-3T ( = KACC 16526T = CGMCC 1.11031T).", }
