Streptacidiphilus toruniensis sp. nov., isolated from a pine forest soil

Two acidophilic actinobacteria, isolates NA14 and NF37(T), were the subject of a polyphasic taxonomic study. Chemotaxonomic and morphological properties of the isolates were characteristic of the genus Streptacidiphilus. The isolates were shown to have identical 16S rRNA gene sequences and to be closely related to Streptacidiphilus neutrinimicus DSM 41755(T) (>99.9 %). However, DNA:DNA relatedness between isolate NF37(T) and the type strain of S. neutrinimicus was found to be low at 11.1 (±3.5) %. A broad range of phenotypic features were shown to distinguish the isolates from their close phylogenetic neighbours. These data shown that the isolates form a novel species of Streptacidiphilus for which the name Streptacidiphilus toruniensis sp. nov. is proposed. The type strain is NF37(T) (= DSM 102291(T) = NCIMB 15025(T)).
