A novel Gram-positive, anaerobic, and coccus-shaped bacterium, designated as strain ChDC B134ᵀ, was isolated from a human postoperative infectious lesion in the right maxilla between the lateral incisor and canine and was characterized by polyphasic taxonomic analysis. 16S rRNA gene sequence analysis revealed that the strain ChDC B134ᵀbelonged to the genus Peptoniphilus, as it showed sequence similarities to Peptoniphilus indolicus KCTC 15023ᵀ(94.0 %) and Peptoniphilus asaccharolyticus KCTC 3321ᵀ(93.8 %). The prevalent fatty acids of of strain ChDC B134ᵀwere C16:0 (20.3 %), C18:1 cis 9 (34.3 %), and C18:0 (13.2 %). The DNA G+C content was 30.9 mol%. The cell wall diamino acid was D-ornithine, which is a property shared by other reference type strains of the genus Peptoniphilus. Based on the results of phenotypic, chemotaxonomic, and phylogenetic analysis, strain ChDC B134ᵀ(=KCOM 1628ᵀ = KCTC 15227ᵀ = JCM 30223ᵀ) should be classified as the type strain of a novel species of genus Peptoniphilus, for which the name Peptoniphilus mikwangii sp. nov. is proposed.
