摘要：A yellow-pigmented, rod-shaped, non-flagellated, aerobic and Gram-reaction-negative bacterium, designated strain SM1212(T), was isolated from intertidal sand of Kongsfjorden, Svalbard. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain SM1212(T) constituted a distinct lineage within the family Flavobacteriaceae. It shared highest 16S rRNA gene sequence similarities with the type strains of Bizionia echini (96.0 %), Lacinutrix jangbogonensis (95.8 %) and Psychroserrpens damuponensis (95.7 %) and <95.6 % sequence similarity with other recognized species in the family Flavobacteriaceae. The strain grew at 4-35 degrees C and with 0-6.0 % (w/v) NaCl. It hydrolysed gelatin, DNA, starch and Tween 80 but did not reduce nitrate to nitrite. The major cellular fatty acids were anteiso-C-15:0, iso-C-15:0, iso-C-15:1 G, anteiso-C-15:1 A, iso-C-15:0 3-OH, C-17:0 2-OH and iso-C-17:(0) 3-OH and the major respiratory quinone was menaquinone MK-6. Polar lipids included phosphatidylethanolamine, one unidentified phospholipid, one unidentified aminophospholipid, three unidentified aminolipids and nine unidentified lipids. The genomic DNA G+C content of strain SM1212(T) was 36.6 mol%. On the basis of data from this polyphasic study, strain SM1212(T) represents a novel species in a new genus in the family Flavobacteriaceae, for which the name Arcticiflavibacter luteus gen. nov., sp. nov. is proposed. The type strain of Arcticiflavibacter luteus is SM1212(T) (=MCCC 1K00234(T)=KCTC 32514(T)).
