Abstract:
A yellow-coloured, rod-shaped, non-motile, Gram-stain-negative and facultative anaerobic bacterium, designated KYW499(T), was isolated from seawater collected at Suncheon Bay, Republic of Korea. The isolate required sea salts for growth. Flexirubin-type pigments were absent. Major cellular fatty acids (>10 % of total) were iso-C15 : 0, iso-C15 : 1 G, iso-C17 : 0 3-OH, iso-C15 : 0 3-OH. The main polar lipids were phosphatidylethanolamine and two unidentified polar lipids. The predominant isoprenoid quinone was MK-6. The genomic DNA G+C content was 31.7 mol%. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain KYW499(T) belonged to the family Flavobacteriaceae, and was related to the genus Flaviramulus. Data from a polyphasic taxonomy study suggested that the isolate represents a novel species of the genus Flaviramulus, for which the name Flaviramulus aquimarinus sp. nov. is proposed. The type strain is KYW499(T) ( = KCTC 23924(T) = JCM 18274(T)).
