Abstract

Two Gram-stain-positive strains, YIT 12363 and YIT 12364, were isolated from human faeces. They were rod-shaped, non-motile, asporogenous, facultatively anaerobic and did not exhibit catalase activity. Comparative analyses of 16S rRNA, and gene sequences demonstrated that the novel strains were members of the genus . On the basis of 16S rRNA gene sequence similarity, the type strains of (95.3 % similarity), subsp. (95.6 %), subsp. (95.3 %) and (95.4 %) were the closest neighbours to strain YIT 12363. For strain YIT 12364, the highest similarity values were observed with the type strains of , and (95.8, 96.0 and 96.0 %, respectively). Phenotypic and genotypic features demonstrated that these strains each represent a separate novel species of the genus , and the names sp. nov. (type strain YIT 12363 = JCM 17471 = DSM 24301) and sp. nov. (type strain YIT 12364 = JCM 17472 = DSM 24302), respectively, are proposed.
