- A pale yellowish pigmented non motile strain 022-2-26T was isolated from a starfish Stellaster equestris. Gram-negative, short rod-shaped, nonmotile bacterium was chemoorganotrophic, alkalitolerant, and mesophilic. The type strain 022-2-26T contained MK-6 as the predominant menaquinone. The major cellular fatty acids were iso-15:0, iso-15:1, 15:0, iso-15:0-2OH and iso-17:0-3OH (together representing 86.4% of the total fatty acids). The DNA base composition was 30.1 mol% GC. A 16S rRNA gene sequence of the type strain 022-2-26T was determined and phylogenetic analyses revealed that 022-2-26T formed a robust clade (confirmed by neighbor-joining, parsimony and maximum-likelihood algorithms and 95% of bootstrap replication) with species of the genus Winogradskyella. The closest related species was Winogradskyella poriferorum UST030701-295T showing a similarity of 96% (59 differences between sequences). On the basis of the phenotypic, chemotaxonomic characteristics and phylogenetic evidence, it is suggested that the bacteria be classified as a novel species, Winogradskyella exilia sp. nov. The type strain is 022-2-26T (KMM 6013T = CIP 109976T).
