| Abstract |
A Gram-positive-staining, coccoid-shaped, non-motile, asporogenous, obligately anaerobic and butyrate-producing bacterium was recovered from a healthy human's faeces. The organism was isolated by the enrichment culture technique using yeast extract-casein hydrolysate-fatty acids broth supplemented with 0.5 % mucin. Phylogenetic analysis of 16S rRNA gene sequences demonstrated that the novel strain should be classified as a member of the Eubacterium desmolans-related cluster in the family Ruminococcaceae. Furthermore, this analysis demonstrated that the type strains of Butyricicoccus pullicaecorum (95.6 %) and Eubacterium desmolans (94.7 %) were the closest phylogenetic neighbours to strain YIT 12789T. However, DNA‒DNA reassociation values with these closest strains were less than 20 %. On the basis of the phenotypic, genotypic and chemotaxonomic features, the novel coccoid-shaped bacterium should be designated as a representative of a novel species of the genus Butyricicoccus, for which the name Butyricicoccus faecihominis sp. nov. is proposed. The type strain is YIT 12789T (=JCM 31056T=DSM 100989T). It is also proposed that Eubacterium desmolans be reclassified in the genus Butyricicoccus as Butyricicoccus desmolans comb. nov.
