Summary: A Gram-stain-negative, strictly aerobic, non-flagellated, non-gliding, oxidase- and catalasepositive and rod-shaped yellow-pigmented bacterium, designated strain SW033T was isolated from a surface seawater sample collected from the South Pacific Gyre (GPS position: 26° 29' S 137° 56' W) during the Integrated Ocean Drilling Program, expedition 329. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain SW033T belonged to the genus Hyunsoonleella and showed the highest 16S rRNA gene sequence similarity with Hyunsoonleella jejuensis CNU004T (96.8%). It showed 94.7-95.8% 16S rRNA gene sequence similarity with respect to members of the genera Jejuia, Arenitalea and Algibacter in the family Flavobacteriaceae. Optimal growth occurred in the presence of 2-3 % (w/v) NaCl, at pH 8.0 and at 28°C. The genomic DNA G+C content of strain SW033T was 36.1 mol%. The major fatty acids were iso-C15 : 1 G, iso-C15 : 0, iso-C17: 0 3-OH, iso-C15 : 0 3-OH and summed feature 3 (comprising C16:1ω7c and/or C16:1ω6c). The major respiratory quinone was menaquinone-6. The major polar lipids were phosphatidylethanolamine, two unidentified aminolipids and four unidentified lipids. On the basis of the polyphasic analyses, strain SW033T is considered to represent a member of a novel species in the genus Hyunsoonleella, for which the name Hyunsoonleella pacifica sp. nov. is proposed. The type strain is SW033T (= CGMCC 1.11009T = JCM 17860T)
