Summary: A Gram-stain-negative, rod-shaped, non-flagellated, strictly aerobic bacterium with gliding motility, designated strain SW150T , was isolated from surface seawater of the South Pacific Gyre (39° 19 S 139° 48 W) during the Integrated Ocean Drilling Program Expedition 329. Optimal growth occurred in the presence of 2-4 % (w/v) NaCl, at pH 7-8 and at 28-30 6C. The dominant fatty acids were iso-C15: 0, iso-C17: 0 3-OH, iso-C15:1 G, C16: 1v6c and/or C16:1v7c and 10-methyl C16:0 and/or iso-C17: 1v9c. The polar lipids of strain SW150T comprised phosphatidylethanolamine, three unknown polar lipids and one unknown aminolipid. The major respiratory quinone was MK-6. The DNA G+C content of strain SW150T was 33.8 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that the novel strain was related most closely to Aquimarina macrocephali JAMB N27T and Aquimarina muelleri KMM 6020T with 97.8 and 96.8 % sequence similarities, respectively. The estimated DNA-DNA hybridization values were 21.00±2.33 % between strain SW150T and A. macrocephali JAMB N27T and 20.60±2.32 % between strain SW150T and Aquimarina megaterium XH134T . On the basis of polyphasic analyses, strain SW150T represents a novel species of the genus Aquimarina, for which the name Aquimarina pacifica sp. nov. is proposed. The type strain is SW150T (5JCM 18214T 5CGMCC 1.12180T ).
