Using the culturomics approach, the previously unknown strain Marseille-P8953ᵀ, was isolated and classified within the Weizmannia genus. Strain Marseille-P8953ᵀ was isolated from the faeces of a healthy subject and consisted of Gram-stain positive, spore-forming, motile rod-shaped cells. A 99.2% similarity was observed between the 16S rRNA gene of strain Marseille-P8953ᵀ (accession number LR735539) and that of Weizmannia coagulans strain NBRC 12583ᵀ (accession number KX261624), its closest phylogenetic relative, while the genome of strain Marseille-P8953ᵀ (3.5 Mpb long, 46.5% GC content) shared the average nucleotide identity by Orthology and digital DNA-DNA Hybridisation values of 95 and 60.4%, respectively. Given the phylogenetic classification and phenotypic characteristics of strain Marseille-P8953ᵀ, we propose the creation of a new species within the Weizmannia genus named Weizmannia faecalis (= CSUR P8953ᵀ = CECT 9904 ᵀ).
