An aerobic, Gram-negative, yellow-pigmented, gliding bacterial strain, designated R60T, was isolated from a marine sediment sample obtained from the Sea of Japan and was characterized by using a polyphasic approach. 16S rRNA gene sequence analysis showed that strain R60T belonged to the genus Winogradskyella, sharing <97 % sequence similarity with the type strains of recognized Winogradskyella species. The main fatty acids of strain R60T were iso-C15 : 0 3-OH, iso-C16 : 0 3-OH, iso-C17 : 0 3-OH, anteiso-C17 : 0 3-OH and iso-C15 : 0, consistent with its assignment to the genus Winogradskyella. On the basis of phenotypic distinctiveness and phylogenetic divergence, strain R60T is considered to represent a novel species of the genus Winogradskyella, for which the name Winogradskyella arenosi sp. nov. is proposed. The type strain is R60T (=KMM 3968T =NRIC 0748T= JCM 15527T).
