Average nucleotide identity (ANI) and dDDH values (%) obtained by pairwise comparison of the nine studied genomes. Compared genomes: 1, Peptostreptococcus faecalis Marseille-P4308T; 2, Peptostreptococcus anaerobius ATCC 27337T; 3, Peptostreptococcus canis CCUG 57081T; 4, Peptostreptococcus russellii RT-10BT; 5, Peptostreptococcus stomatis W2278T; 6, Asaccharospora irregularis DSM 2635T; 7, Clostridioides difficile DSM 1296T; 8, Clostridioides mangenotii DSM 1289T; 9, Clostridium hiranonis DSM 13275T. OrthoANI values are shown on right bottom (in bolt) and dDDH values calculated using GGDC formula 2 software (DDH estimates based on HSP identities/length) shown on upper left. The empty boxes between them are 100%.
