Summary of "Arcticiflavibacter luteus gen. nov., sp. nov., a novel member of the family Flavobacteriaceae isolated from Arctic intertidal sand."

A yellow-colored, rod-shaped, non-flagellated, aerobic and Gram-negative bacterium, designated strain SM1212T, was isolated from intertidal sand of Kongsfjorden, Svalbard. Phylgenetic analysis based on the 16S rRNA gene sequences revealed that strain SM1212T constituted a distinct lineage within the family Flavobacteriaceae. It shared the highest 16S rRNA gene sequence similarities with Bizionia echini (96.0 %), Lacinutrix jangbogonensis (95.8 %) and Psychroserpens damuponensis (95.7 %) and < 95.6 % sequence similarities with other recognized species in the family Flavobacteriaceae. The strain grew at 4-35°C and with 0-6.0 % (w/v) NaCl. It hydrolyzed gelatin, DNA, strach and tween 80 but did not reduce nitrate to nitrite. The major cellular fatty acids were anteiso-C15:0, iso-C15:0, iso-C15:1 G, anteiso-C15:1 A, iso-C15:0 3-OH, C17:0 2-OH and iso-C17:0 3-OH and the major respiratory quinone was MK-6. Polar lipids included phosphatidylethanolamine, one unidentified phospholipid, one unidentified aminophospholipid, three unidentified aminolipids and nine unidentified lipids. Genomic DNA G+C content of strain SM1212T was 36.6 mol%. On the basis of the polyphasic evidence presented in this study, strain SM1212T 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 SM1212T (=MCCC 1K00234T= KCTC 32514T).
