    Abstract:
    A Gram-stain-negative, rod-shaped, bacterial strain, B448-2T, was isolated from an ice core from the Muztagh Glacier, on the Tibetan Plateau. B448-2T grew optimally at pH 7.0 and 20 °C in the presence of 0-1.0 % (w/v) NaCl. The results of 16S rRNA gene sequence similarity analysis indicated that B448-2T was closely related to Massilia eurypsychrophila CGMCC 1.12828T, Rugamonas rubra CCM3730T and Duganella zoogloeoides JCM20729T at levels of 97.8, 97.7  and 97.3 %, respectively. The predominant fatty acids of B448-2T were summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c) and C16 : 0. The predominant isoprenoid quinone was Q-8. The major polar lipids were phosphatidylethanolamine, phosphatidylglycerol and diphosphatidylglycerol. The genomic DNA G+C content of the strain was 66.1 mol%. In DNA-DNA hybridization tests, B448-2T shared 37.6 % DNA-DNA relatedness with Massilia eurypsychrophila CGMCC 1.12828T. On the basis of the results for phenotypic and chemotaxonomic characteristics, B448-2T was considered to represent a novel species of the genus Massilia, for which the name Massiliaglaciei sp. nov. is proposed. The type strain is B448-2T (=JCM 30271T=CGMCC 1.12920T).
