Strain TSBY 67T was isolated during a study on the phylogenetic diversity of culturable bacteria from alpine permafrost in Tianshan Mountains, China. On the basis of 16S rRNA gene sequence analysis, strain TSBY 67T was closely related to members of the genus Chryseobacterium and exhibited 96.8 % 16S rRNA gene sequence similarity to Chryseobacterium aquaticum 10-46T and Chryseobacterium soldanellicola PSD 1-4T. Strain TSBY 67T grew aerobically, at 4–37 °C, with 0–2 % NaCl and at pH 6–8. Cells were Gram-staining negative, non-motile and non-spore-forming rods. The dominant cellular fatty acids were iso-C15 : 0 (26.9 %), iso-C17 : 0 3-OH (16.1 %) and iso-C17 : 1ω9c (15.4 %). The G+C content of the DNA was 33.5 mol%. Strain TSBY 67T was distinguishable from its closest phylogenetic neighbours by a combination of phenotypic characteristics. Therefore, strain TSBY 67T represents a novel species of the genus Chryseobacterium, for which the name Chryseobacterium xinjiangense sp. nov. is proposed. The type strain is TSBY 67T ( = NRRL B-51308T = CCTCC AB 207183T).
