A novel Gram-stain-negative, rod-shaped, non-flagellated, strictly aerobic strain with gliding motility, designated XH134(T), was isolated from surface seawater of the South Pacific Gyre (45 degrees 58' S 163 degrees 11' W) during the Integrated Ocean Drilling Program Expedition 329. The major respiratory quinone of strain XH134(T) was MK-6. The dominant fatty acids of strain XH134(T) were iso-C-15:0, iso-C-15:1 G, C-16:1 omega 6c and/or C-16:1 omega 7c, iso-C-17:0 3-OH, iso-C-(15:0) 3-OH and 10-methyl C-16:0 and/or iso-C-17:1 omega 9c. The polar lipids of strain XH134(T) comprised phosphatidylethanolamine, one unknown aminolipid and three unknown polar lipids. The DNA G+C content of strain XH134(T) was 32.4 mol%. Phylogenetic analyses based on 16S rRNA gene sequences showed that the novel strain was related most closely to Aquimarina macrocephali JAMB N27(T) with 96.9% sequence similarity. A number of phenotypic characteristics distinguished strain XH134(T) from described members of the genus Aquimarina. On the basis of combined phenotypic and phylogenetic analyses, strain XH134(T) represents a novel species of the genus Aquimarina, for which the name Aquimarina megaterium sp. nov. is proposed. The type strain is XH134(T) (=CGMCC 1.12186(T)=JCM 18215(T))
