A Gram-stain-positive, non-motile, catalase-positive and cytochrome c oxidase-negative bacterium, designated strain S20-107T, was isolated from alpine forest soil. Growth occurred at 0–30 °C, at pH 6–9 and in the presence of 0–3 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain S20-107T was related to the genus Nakamurella and had the highest 16S rRNA gene sequence similarity with Nakamurella flavida DS-52T (96.1 %). Strain S20-107T showed <96.1% 16S rRNA gene sequence similarities to all other recognized members of the genus Nakamurella. The cell-wall peptidoglycan contained meso-diaminopimelic acid. The major whole-cell sugars were glucose, galactose, mannose, arabinose, ribose and rhamnose. The strain contained MK-8(H4) as the predominant menaquinone and diphosphatidylglycerol, phosphatidylethanolamine and an unidentified aminophospholipid as the major polar lipids. The major cellular fatty acids were anteiso-C15 : 0, C16 : 0, summed feature 3 (C16 : 1ω6c and/or C16 : 1ω7c and/or iso-C15 : 0 2-OH) and iso-C16 : 0. The genomic DNA G+C content was 70.5 mol%. Combined data of phylogenetic, phenotypic and chemotaxonomic analyses demonstrated that strain S20-107T represents a novel species of the genus Nakamurella, for which the name Nakamurella silvestris sp. nov. is proposed. The type strain is S20-107T (=DSM 102309T=LMG 29427T).
