Winogradskyella arenosi sp. nov., a member of the family Flavobacteriaceae isolated from marine sediments from the Sea of Japan

An aerobic, Gram-negative, yellow-pigmented, gliding bacterial strain, designated R60(T), 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 R60(T) belonged to the genus Winogradskyella, sharing <97 % sequence similarity with the type strains of recognized Winogradskyella species. The main fatty acids of strain R60(T) were iso-C(15 : 0) 3-OH, iso-C(16 : 0) 3-OH, iso-C(17 : 0) 3-OH, anteiso-C(17 : 0) 3-OH and iso-C(15 : 0), consistent with its assignment to the genus Winogradskyella. On the basis of phenotypic distinctiveness and phylogenetic divergence, strain R60(T) 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 R60(T) (=KMM 3968(T) =NRIC 0748(T)= JCM 15527(T)).
