sp. nov., isolated from an ice core Open Access

Abstract

A Gram-stain-positive, rod-shaped and motile bacterium with lateral flagellum, designated T3246-1, was isolated from an ice core, which was drilled from Hariqin Glacier on the Tibetan Plateau, PR China. It grew optimally at 20 °C, pH 7–8 and in the presence of 3 % (w/v) NaCl. The major fatty acid of strain T3246-1 was anteiso-C. Major polar lipids were diphosphatidylglycerol, phosphatidylglycerol and phosphatidylinositol. MK-8 was the dominant isoprenoid quinone. The whole-cell sugars were rhamnose, xylose and mannose. The major cell-wall peptidoglycan was lysine. The genomic DNA G+C content of the strain was 71.4 mol%. Results of phylogenetic analysis based on 16S rRNA gene sequences showed that strain T3246-1 formed a lineage within the genus and was closely related to YIM 93306 with 95.99 % similarity. The average nucleotide identity value between strain T3246-1 and YIM 93306 was 76.65 %. Based on phenotypic and chemotaxonomic characteristics, strain T3246-1 was considered to represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is T3246-1 (=CGMCC 1.13535=JCM 32923).
