Abstract
A Gram-stain-negative, non-motile, rod-shaped bacterial strain, AH-M5T, which was isolated from a tidal flat sediment at Aphae Island in South Korea, was characterized taxonomically. Strain AH-M5T grew optimally at 25 °C, at pH 7.0-8.0 and in presence of 2.0 % (w/v) NaCl. Phylogenetic trees based on 16S rRNA gene sequences revealed that strain AH-M5T clustered coherently with the type strains of Mangrovimonas yunxiaonensis and Meridianimaribacter flavus, showing 93.4-94.3% sequence similarity. The novel strain exhibited 16S rRNA gene sequence similarity values of less than 93.4% to the type strains of other recognized species. Strain AH-M5T contained MK-6 as the predominant menaquinone and iso-C15:1 G, iso-C15:0, iso-C17:0 3-OH and summed feature 3 (C16:1ω7c and/or C16:1ω6c) as the major fatty acids. The polar lipid profile of strain AH-M5T containing phosphatidylethanolamine and one unidentified lipid as major components was differentiated from those of the type strains of Mangrovimonas yunxiaonensis and Meridianimaribacter flavus. The DNA G+C content of strain AH-M5T was 34.8 mol%. Differential phenotypic properties, together with the phylogenetic and chemotaxonomic data, demonstrated that strain AH-M5T is distinguished from Mangrovimonas yunxiaonensis and Meridianimaribacter flavus. On the basis of the data presented, strain AH-M5T is considered to represent a novel genus and species within the family Flavobacteriaceae, for which the name Seonamhaeicola aphaedonensis gen. nov., sp. nov. is proposed. The type strain of the type species is AH-M5T (= KCTC 32578T = CECT 8487T).
