A novel psychrophilic, yellow-pigmented and obligate aerobic bacterium, strain 0499T, was isolated from the China No.1 glacier. Strain 0499T displayed the common phenotypic and chemotaxonomic features of the genus Flavobacterium, containing menaquinone-6 (MK-6) as the major quinone and C15 : 0, iso-C15 : 0, C17 : 1
6c and summed feature 3 (C16 : 1
7c/iso-C15 : 0 2-OH) as the major fatty acids. Optimal growth occurred at 21 °C. The genomic DNA G+C content was 36.5 mol%. Phylogenetic analysis based on 16S rRNA gene sequence similarity showed that strain 0499T was related to members of the genus Flavobacterium, sharing the highest sequence similarities with Flavobacterium succinicans (97.9 %), Flavobacterium granuli (97.4 %) and Flavobacterium hydatis (97.2 %). On the basis of phenotypic characteristics, phylogenetic analysis and DNADNA relatedness data, a novel species Flavobacterium glaciei is proposed with strain 0499T (=CGMCC 1.5380T=JCM 13953T) as the type strain.
A table detailing the cellular fatty acid contents of Flavobacterium glaciei sp. nov. and related taxa is available as supplementary material in IJSEM Online.
