Phylogenetic analysis based on comparative 16S rRNA gene sequencing showed that this strain clustered with species of the family ‘ Acidaminococcaceae ’, with 94.9 % similarity to Megamonas hypermegale DSM 1672 T and less than 91 % similarity with type strains of Pectinatus species. Sequence similarities of at least 98–99 % were observed with numerous sequences deposited in GenBank of uncultured strains from human and chicken caecal contents, but this strain is the first isolate of this taxon to be cultivated and described. On the basis of morphological, physiological and phylogenetic features, this strain should be assigned to a novel species in the genus Megamonas , for which the name Megamonas rupellensis sp. nov. is proposed. The type strain is strain FM1025 T (=DSM 19944 T =CIP 109788 T ). The GenBank/EMBL/DDBJ accession number for the 16S rRNA gene sequence of strain FM1025 T is EU346729 .
