Abstract:
A Gram-stain-negative, rod-shaped, yellow-pigmented, gliding bacterial strain, designated S5-23-3T, was isolated from a sediment sample of the Yellow Sea in China. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain S5-23-3T was related to the genus Winogradskyella and had highest 16S rRNA gene sequence similarities with Winogradskyella arenosi JCM 15527T (97.6 %), Winogradskyella rapida CECT 7392T (97.4 %) and Winogradskyella undariae KCTC 32261T (97.2 %). The predominant cellular fatty acids were iso-C15 : 0, iso-C15 : 1 G, iso-C15 : 0 3-OH and iso-C17 : 0 3-OH. Strain S5-23-3T contained MK-6 as the predominant menaquinone. The polar lipid profile contained phosphatidylethanolamine, two aminolipids, one aminoglycolipid, one aminophospholipid, one unidentified phospholipid and seven unidentified polar lipids. The genomic DNA G+C content of strain S5-23-3T was 36.1 mol%. Combined data from phenotypic, chemotaxonomic, phylogenetic and DNA-DNA relatedness studies demonstrated that strain S5-23-3T is a representative of a novel species of the genus Winogradskyella, for which the name Winogradskyellasediminis sp. nov. (type strain S5-23-3T=LMG 28075T=DSM 28134T) is proposed.
