Abstract

A yellow-coloured, rod-shaped, Gram-reaction-negative, aerobic bacterial strain, designated JC2132, 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 JC2132 represented a distinct phyletic line that reflected a novel generic status within the family 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 , but overall phenotypic traits demonstrated that strain JC2132 was not closely affiliated with any previously described genera. Based on taxonomic data obtained using a polyphasic approach, it is proposed that strain JC2132 represents a novel species in a new genus belonging to the family , for which the name gen. nov., sp. nov. is proposed; the type strain of the type species is JC2132 ( = KACC 14152 = JCM 17111).
