Kordia periserrulae sp. nov., isolated from a marine polychaete Periserrula leucophryna, and emended description of the genus Kordia.

A Gram-negative, chemoheterotrophic, yellow-pigmented, non-motile, flexirubin-negative, facultatively anaerobic bacterium, designated strain IMCC1412(T), was isolated from a marine polychaete Periserrula leucophryna inhabiting a tidal flat of the Yellow Sea, Korea. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain IMCC1412(T) was most closely related to Kordia algicida, with a sequence similarity of 96.7 %, but only distantly related to other species in the family Flavobacteriaceae (<92 % similarity). The G+C content of the DNA was 37.3 mol%. The strain contained MK-6 as the major respiratory quinone and phosphatidylethanolamine, unidentified aminolipids and unidentified polar lipids as the major polar lipids. On the basis of phylogenetic distinctiveness and differential phenotypic characteristics, strain IMCC1412(T) ( = KACC 14311(T) = KCTC 22801(T) = NBRC 106077(T)) should be assigned to the genus Kordia as the type strain of a novel species, for which the name Kordia periserrulae sp. nov. is proposed. An emended description of the genus Kordia is also presented.
