title: Chelatococcus reniformis sp. nov., isolated from a glacier.
abstract: A Gram-stain-negative, non-motile, reniform bacterial strain, B2974T, was isolated from an ice core of the Muztagh Glacier, on the Tibetan Plateau, China. Strain B2974T grew optimally at pH 7.0-7.5 and 25-30 °C in the presence of 0-2.0 % (w/v) NaCl. 16S rRNA gene sequence similarity analysis indicated that strain B2974T was closely related to Chelatococcus asaccharovorans LMG 25503T at a level of 97.1 %. The major quinone of strain B2974T was ubiquinone Q10. The predominant fatty acids were summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c) and C19 : 0 cyclo ω8c. sym-Homospermidine was the major polyamine. The genomic DNA G+C content of the strain was 64 mol%. In DNA-DNA hybridization tests, strain B2974T shared 49.32 % DNA-DNA relatedness with the type strain of Chelatococcus asaccharovorans LMG 25503T. Based on the results of phenotypic and chemotaxonomic characteristics, strain B2974T was considered as a novel species of the genus Chelatococcus, for which the name Chelatococcus reniformis sp. nov. is proposed. The type strain is B2974T (=JCM 30308T=CGMCC 1.12919T).
