Abstract
A novel psychrophilic, yellow-pigmented and obligate aerobic bacterium, strain 0499(T), was isolated from the China No.1 glacier. Strain 0499(T) displayed the common phenotypic and chemotaxonomic features of the genus Flavobacterium, containing menaquinone-6 (MK-6) as the major quinone and C(15 : 0), iso-C(15 : 0), C(17 : 1)omega6c and summed feature 3 (C(16 : 1)omega7c/iso-C(15 : 0) 2-OH) as the major fatty acids. Optimal growth occurred at 21 degrees C. The genomic DNA G+C content was 36.5 mol%. Phylogenetic analysis based on 16S rRNA gene sequence similarity showed that strain 0499(T) 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 DNA-DNA relatedness data, a novel species Flavobacterium glaciei is proposed with strain 0499(T) (=CGMCC 1.5380(T)=JCM 13953(T)) as the type strain.
