Reclassification of [Flavobacterium] ferrugineum as Terrimonas ferruginea gen. nov., comb. nov., and description of Terrimonas lutea sp. nov., isolated from soil

Strain DY T , 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 T 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 T could be clearly differentiated from other members of the genus Flavobacterium . Strain DY T 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 DY T 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 DY T =IAM 15284 T =CCTCC AB205006 T ), respectively.
