• A red–pink, Gram-negative, rod-shaped, non-motile, non-spore-forming bacterium, designated strain DK6-37 was isolated from the permafrost region of Qilian Mountains in northwest of China. Phylogenetic analysis based on 16S rRNA gene sequencing indicated that this isolate represents a novel member of the genus Hymenobacter , with low sequence similarities (<97 %) to recognized Hymenobacter species. Optimum growth was observed at 28 °C, pH 7.0 and 0 % NaCl. The strain was found to contain MK-7 as the predominant menaquinone. The polar lipids were identified as phosphatidylethanolanmine, two unknown aminophospholipids, one unknown aminolipid and three unknown polar lipids. The major fatty acids were identified as summed feature 3 (C 16:1 ω 7 c /C 16:1 ω 6 c as defined by MIDI), summed feature 4 (anteiso-C 17:1 B/iso-C 17:1 I), C 16:1 ω 5 c , iso-C 17:0 3-OH, iso-C 15:0 and C 18:0 . The DNA G + C content was determined to be 67.4 mol %. On the basis of the polyphasic evidence presented, it is proposed that strain DK6-37 represents a novel species of the genus Hymenobacter , for which the name Hymenobacter qilianensis sp. nov. is proposed. The type strain is DK6-37 T (= CGMCC 1.12720 T  = JCM 19763 T ).
