Strain DYT, 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 DYT was [Flavobacterium] ferrugineum 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, [Flavobacterium] ferrugineum IAM 15098(Te) could be clearly differentiated from other members of the genus Flavobacterium. Strain DYT and [Flavobacterium] ferrugineum IAM 15098(T) Could be easily distinguished from neighbouring taxa by morphological features (non-motile, non-gliding and non-filamentous single cells). Therefore, it is proposed that [Flavobacterium] ferrugineum IAM 15098(T) and strain DYT represent two separate species of a new genus, Terrimonas gen. nov., with the names Terrimonas ferruginea comb. nov. (type species; type strain IAM 15098(T) = ATCC 13524(T)) and Terrimonas lutea sp. nov. (type strain DYT = IAM 15284(T) = CCTCC AB205006(T)), respectively.
