Three Gram-negative, rod-shaped, non-spore-forming eubacterial strains were isolated in western Montana, USA, and subjected to taxonomic studies. Strains NWG-II14 and NWER-II11 were isolated from hyporheic sediments of a large alluvial flood plain, whereas strain G-1 was isolated from a conifer forest soil. On the basis of 16S rRNA gene sequence similarity, strains NWG-II14, NWER-II11 and G-1 were shown to belong to the family and are most closely related to various species of the genus . The results of molecular, physiological and biochemical tests allowed genotypic and phenotypic differentiation of these three strains from 23 species with validly published names. The three isolates therefore represent novel species, for which the names sp. nov. (type strain NWG-II14 =DSM 19625 =LMG 24260), sp. nov. (type strain NWER-II11 =DSM 19624 =LMG 24258) and sp. nov. (type strain G-1 =DSM 19626 =LMG 24259) are proposed.
