Two aerobic bacterial strains, designated SP1PR4 T and SP1PR5, were isolated from tundra soil samples collected from Saana fjeld, North-western Finland (696 039 N 206 509 E). Cells of both strains were Gram-negative, non-motile rods. Phylogenetic analysis indicated that the strains belong to the genus Terriglobus in subdivision 1 of the phylum Acidobacteria. Strains SP1PR4 T and SP1PR5 shared identical BOX and ERIC fingerprints and 99.7% 16S rRNA gene similarity indicating that, together with their identical physiological features, these strains are members of the same species. The 16S rRNA gene sequence similarity of SP1PR4 T and SP1PR5 with Terriglobus roseus DSM 18391 T was 97.1%. A low DNA-DNA hybridization value (,20%) and rpoB gene sequence similarity (83.6%) with T. roseus DSM 18391 T indicated that the tundra soil isolates represent novel members of the genus Terriglobus. Strains SP1PR4 T and SP1PR5 grew at pH 4.5-7.5 and 4-30 6C. Sugars were the preferred growth substrates. The major cellular fatty acids were iso-C 15: 0, C 16: 1v7c, iso-C 13: 0 and C 16: 0. The DNA G+C content of strain SP1PR4 T was 57.3 mol%. Based on phylogenetic, chemotaxonomic and physiological analyses, the name Terriglobus saanensis sp. nov. is proposed to accommodate the two strains; the type strain is SP1PR4 T (5DSM 23119 T 5ATCC BAA-1853 T).
