During a culturomics study of the human gut, strain 17EGHSPOS18-1\n                    <jats:sup>T<\/jats:sup>\n                    was isolated from the faeces of a healthy adult. Here, we conducted a taxonomic study of the strain. Phylogenetic analysis based on 16S rRNA gene sequences placed strain 17EGHSPOS18-1\u1d40 in the\n                    <jats:italic>Anaerostipes<\/jats:italic>\n                    cluster. This placement was supported by a core gene-based phylogenetic analysis. Strain 17EGHSPOS18-1\n                    <jats:sup>T<\/jats:sup>\n                    shared average nucleotide identity (ANI) values of &lt;80% and digital DNA\u2013DNA hybridization (dDDH) values of &lt;30% with known\n                    <jats:italic>Anaerostipes<\/jats:italic>\n                    spp., indicating that it does not belong to any known species of the genus\n                    <jats:italic>Anaerostipes<\/jats:italic>\n                    . Physiological and chemotaxonomic characteristics, including carbohydrate utilization patterns, enzyme activities, major cellular fatty acid profiles and major fermentation end-product profiles, further distinguished the strain from the known\n                    <jats:italic>Anaerostipes<\/jats:italic>\n                    spp. The novel strain was able to metabolize only a limited number of carbohydrates, consistent with its restricted repertoire of glycoside hydrolase family proteins. These findings indicate that 17EGHSPOS18-1\n                    <jats:sup>T<\/jats:sup>\n                    represents a novel species, for which the name\n                    <jats:italic>Anaerostipes stercorihominis<\/jats:italic>\n                    sp. nov. is proposed. The type strain is 17EGHSPOS18-1\n                    <jats:sup>T<\/jats:sup>\n                    (= JCM 38261\n                    <jats:sup>T<\/jats:sup>\n                    = DSM 121506\n                    <jats:sup>T<\/jats:sup>\n                    ). Furthermore, during this taxonomic study, we found that\n                    <jats:italic>Anaerostipes hominis<\/jats:italic>\n                    and\n                    <jats:italic>Anaerostipes faecis<\/jats:italic>\n                    share ANI and dDDH values above the species discrimination thresholds, indicating that they should be assigned to the same taxon.
