A novel cold-living, Gram-stain-negative, yellow-pigmented and obligately aerobic bacterium designated strain 0563T was isolated from the China No. 1 glacier. Phylogenetic analysis showed that strain 0563T was a member of the genus Flavobacterium, sharing the highest 16S rRNA gene sequence similarities with Flavobacterium limicola JCM 11473T (98.5 %) and Flavobacterium psychrolimnae NBRC 102679T (98.2 %). The genomic DNA G+C content was 34.8 mol%. Strain 0563T displayed the common phenotypic and chemotaxonomic features of the genus Flavobacterium, containing menaquinone-6 (MK-6) as the major quinone and iso-C15 : 0, iso-C15 : 0 3-OH, summed feature 3 (comprising C16 : 1 ω7c and/or C16 : 1 ω6c), C15 : 1 ω6c, iso-C15 : 1 G and iso-C16 : 0 3-OH as the major fatty acids. On the basis of phenotypic characteristics, phylogenetic analysis and DNA–DNA relatedness data, the novel species Flavobacterium tiangeerense sp. nov. is proposed; the type strain is 0563T (=CGMCC 1.6847T =JCM 15087T).
