| 摘要: | Gram-positive, rod-shaped bacteria, strains Hh8(T), Hh15(T) and Hh40-2, were isolated from the No. 1 glacier in Xinjiang, north-west China. Colonies of strain Hh8(T) were orange-yellow, convex and round on PYG plates. Strain Hh8(T) grew at 0-19 degrees C and pH 5.5-10.5. Colonies of strain Hh15(T), which was able to grow at 0-20 degrees C and pH 5.5-12, were lemon yellow, convex and round on PYG plates. Phylogenetic analysis based on 16S rRNA gene sequences showed that these three strains were related to members of the genus Cryobacterium. The major cellular fatty acids of the novel strains were anteiso-C-15:0, iso-C-16:0, iso-C-15:0 and anteiso-C-15:1 A. On the basis of phenotypic characteristics, phylogenetic analysis and DNA-DNA relatedness data, two novel species, Cryobacterium flavum sp. nov. (type strain Hh8(T)=CGMCC 1.11215(T)=NBRC 107879(T)) and Cryobacterium luteum sp. nov. (type strain Hh15(T)=CGMCC 1.11210(T)=NBRC 107880(T)), are proposed. |
