Winogradskyella thalassocola gen. nov., sp nov., Winogradskyella epiphytica sp nov and Winogradskyella eximia sp nov., marine bacteria of the family Flavobactefiaceae

Three novel heterotrophic, Gram-negative, yellow-pigmented, aerobic, gliding, oxidase- and catalase-positive bacteria were isolated from algae collected in the Gulf of Peter the Great, Sea of Japan. 16S rRNA gene sequence analysis revealed that the strains studied represented members of the family Flavobacteriaceae and showed 93(.)5-93(.)8% similarity with their closest relative, Psychroserpens burtonensis. The DNA G + C content of the strains was 34-37 mol%. The major respiratory quinone was MK-6. The predominant fatty acids were iso-C-15:0, anteiso-C-15:0, iso-C-15:1, iso-C-16:0 and iso-C-17:0-30H. On the basis of their phenotypic, chemotaxonomic, genotypic and phylogenetic characteristics, the newly described bacteria have been assigned to the new genus Winogradskyella gen. nov., as Winogradskyella thalassocola sp. nov. (type strain, KMM 3907(T)=KCTC 12221(T)=LMG 22492(T)=DSM 15363(T)), Winogradskyella epiphytica sp. nov. (type strain, KMM 3906(T) =KCTC 12220(T)=LMG 22491(T)=CCUG 47091(T)) and Winogradskyella eximia sp. nov. (type strain, KMM 3944(T) (= KCTC 12219(T)=LMG 22474(T)).
