title: Nocardioides glacieisoli sp. nov., isolated from a glacier.
abstract: A Gram-stain-positive, rod-shaped, non-spore-forming bacterium (strain HLT3-15T) was isolated from the ice tongue surface of the Hailuogou glacier in Szechwan Province, PR China. Phylogenetic analysis, based on 16S rRNA gene sequences, revealed that strain HLT3-15T belonged to the genus Nocardioides. The highest levels of sequence similarities were found with Nocardioides hwasunensis CGMCC 4.6881T and Nocardioides ganghwensis CGMCC 4.6875T (98.5 % and 98.3 %, respectively). However, DNA-DNA relatedness demonstrated that strain HLT3-15T was distinct from its closest phylogenetic neighbours. The major cellular fatty acids of strain HLT3-15T were C17 : 1ω8c and iso-C16 : 0. Strain HLT3-15T contained ll-2,6-diaminopimelic acid as the diamino acid in the cell-wall peptidoglycan and MK-8(H4) as the predominant menaquinone. On the basis of a polyphasic approach, a novel species, Nocardioides glacieisoli sp. nov., is proposed with HLT3-15T ( = CGMCC 1.11097T = NBRC 109781T) as the type strain.
