Flagellimonas maritima sp. nov., isolated from surface seawater.

An aerobic, non-motile, rod-shaped and Gram-stain-negative marine bacterium, designated as HME9304T, was isolated from surface seawater of the Yellow Sea. Growth was observed at 10-35 °C (optimum, 30 °C), pH 6-8 (pH 7) and with 1-5 % NaCl (2 %). The major fatty acids of strain HME9304T were iso-C15 : 1 G, iso-C15 : 0, iso-C17 : 0 3-OH and summed feature 3 (C16 : 1 ω7c and/or C16 : 1 ω6c). The only respiratory quinone was menaquinone-6. The major polar lipids were phosphatidylethanolamine, two unidentified aminolipids, one unidentified glycolipid and five unidentified polar lipids. Results of phylogenetic analysis based on the 16S rRNA gene sequence indicated that strain HME9304T was affiliated with the genus Flagellimonas. Its closest type strains were Flagellimonas aquimarina ECD12T (95.5 % sequence similarity), Flagellimonas flava A11T (95.4 %), Flagellimonas pacifica SW169T (94.9 %) and Flagellimonas eckloniae DOKDO 007T (94.6 %). The DNA G+C content of the genomic DNA was 38.1 mol%. Phylogenetic, phenotypic and chemotaxonomic characteristics suggested that strain HME9304T represents a novel species of the genus Flagellimonas within the family Flavobacteriaceae, for which the name  Flagellimonas maritima sp. nov. is proposed. The type strain is HME9304T (=KCTC 32464T=KACC 17618T=CECT 8418T).
