Abstract

Strain DY, which was isolated from garden soil in Japan, was subjected to a polyphasic taxonomic study. Sequence analysis of the 16S rRNA gene and the GyrB protein revealed that the closest relative of strain DY was [] Sickles and Shaw 1934, with 94.8 and 90.1 % similarity, respectively. The two strains had similar chemotaxonomic characteristics, with menaquinone 7 as the major quinone system, 47.2–48.9 mol% DNA G+C content and 15 : 0 iso, 15 : 1 iso, 17 : 0 iso 3-OH and summed feature 3 as the major fatty acids. Based on genotypic and phenotypic characteristics, [] IAM 15098 could be clearly differentiated from other members of the genus . Strain DY and [] IAM 15098 could be easily distinguished from neighbouring taxa by morphological features (non-motile, non-gliding and non-filamentous single cells). Therefore, it is proposed that [] IAM 15098 and strain DY represent two separate species of a new genus, gen. nov., with the names comb. nov. (type species; type strain IAM 15098=ATCC 13524) and sp. nov. (type strain DY=IAM 15284=CCTCC AB205006), respectively.
