Abstract

A Gram-stain-negative, rod-shaped, aerobic, non-motile bacterium, designated Y620-1, was isolated from a glacier on the Tibetan Plateau, China. The 16S rRNA gene sequence of the novel isolate shared 93.6–95.1 % similarity with type strains of species of the genus . The major fatty acids of strain Y620-1 were summed feature 3 (Cω7 and/or iso-C 2-OH), iso-C, Cω5 and iso-C 3-OH. The predominant isoprenoid quinone and polar lipid were MK-7 and phosphatidylethanolamine (PE), respectively. The DNA G+C content was 44.4±0.3 mol% ( ). Flexirubin-type pigment was produced. The novel isolate was classified in the genus , but a number of phenotypic characteristics distinguished the novel isolate from type strains of species of the genus . From these genotypic and phenotypic data, it is evident that strain Y620-1 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is Y620-1 ( = JCM 18589 = CGMCC 1.12215).
