Taeania maliponensis gen. nov., sp. nov., a member of the family Flavobacteriaceae isolated from seawater

A Gram-strain-negative, rod-shaped, non-motile bacterial strain, designated MM-8^T, was isolated from seawater in the Korean peninsula. Strain MM-8^T was found to grow optimally at pH 7.0–8.0, at 30 °C and in the presence of 2% (w/v) NaCl. A neighbour-joining phylogenetic tree based on 16S rRNA gene sequences showed that strain MM-8^T falls within the clade comprising members of the genera Actibacter, Lutimonas and Namhaeicolain the family Flavobacteriaceae. Strain MM-8^T exhibited 16S rRNA gene sequence similarity values of 94.4–96.9% with respect to the type strains of members of the genera Actibacter, Lutimonas and Namhaeicola. Strain MM-8^T was found to contain MK-6 (90.0 %) and MK-7 (10.0 %) as the predominant menaquinones and iso-C_{15: 0} (32.4%), iso-C_{15: 1} G(11.4 %) and iso-C_{15: 0} 3-OH (10.1 %) as the major fatty acids. The major polar lipids were identified as phosphatidylethanolamine and an unidentified lipid. The DNA G+C content of strain MM-8^T was determined to be 40.7 mol%. Differential phenotypic properties, together with the phylogenetic distinctiveness, demonstrate that strain MM-8^T is distinguishable from the type strains of type species of the genera Actibacter, Lutimonas and Namhaeicola. On the basis of the data presented, strain MM-8^T is considered to represent a novel genus and species, for which the name Taeania maliponensis gen. nov., sp. nov. is proposed. The type strain is MM-8^T (=KCTC 52209^T=NBRC 112238^T).
