Abstract

A Gram-stain-negative, orange-coloured, rod-shaped bacterium, designated strain Th68T, was isolated from the intestine of flounder (Paralichthys olivaceus). The isolate required sea salts for growth. Gliding motility was not observed. Flexirubin-type pigments were present. 16S rRNA gene sequence analysis indicated that strain Th68T represented a distinct phyletic line within the family Flavobacteriaceae with less than 96.1% similarity to members of the recognized genera of the family. The DNA G+C content was 33.0 mol%. The major fatty acids were iso-C15:0, iso-C15:1 G, iso-C17:0 3-OH and iso-C15:0 3-OH. The major polar lipids were phosphatidylethanolamine,twounidentifiedaminolipidsandtwounidentifiedpolarlipids.Menaquinone6(MK-6) was the only respiratory quinone. On the basis of the phenotypic, chemotaxonomic and phylogenetic data, strain Th68T represents a novel species of a new genus in the family Flavobacteriaceae, for which the name Flavirhabdus iliipiscaria gen. nov., sp. nov. is proposed. The type strain of Flavirhabdus iliipiscaria is Th68T (5JCM 18637T5KCTC 32141T).
