Snuella lapsa gen. nov., sp. nov., isolated from tidal flat sediment

Abstract

A yellow-coloured, rod-shaped, Gram-reaction-negative, aerobic bacterial strain, designated JC2132T, was isolated from a tidal flat sediment sample from Ganghwa Island, Korea. The isolate required sea salts for growth. Cells produced non-diffusible carotenoid pigments, but flexirubin-type pigments were absent. Gliding motility was observed. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain JC2132T represented a distinct phyletic line that reflected a novel generic status within the family Flavobacteriaceae with relatively low sequence similarities (<95 %) to members of other genera with validly published names. The predominant isoprenoid quinone (MK-6) and DNA G+C content (35 mol%) were consistent with assignment of the isolate to the family Flavobacteriaceae, but overall phenotypic traits demonstrated that strain JC2132T was not closely affiliated with any previously described genera. Based on taxonomic data obtained using a polyphasic approach, it is proposed that strain JC2132T represents a novel species in a new genus belonging to the family Flavobacteriaceae, for which the name Snuella lapsa gen. nov., sp. nov. is proposed; the type strain of the type species is JC2132T ( = KACC 14152T = JCM 17111T).
