Phylogenetic positions of Tenericutes families in Bacilli. Representative genomes from orders of Bacilli were used to construct the phylogenomics tree using concatenated conserved proteins by IQ-TREE and RAxML. The bootstrap values were shown as triangles (50–90) and dots (> 90) with a red color for the results of RAxML and deep blue for those of IQ-TREE, respectively. The red clades represent the orders of Tenericutes. The Bacilli genomes for Erysipelotrichales and the other orders in purple were selected from GTDB. RFN20, RF39, ML615 were environmental clades named in GTDB and were phylogenetically placed within the NCBI clades consisting of human gut lineages 1, 2 and bioreactor group, respectively
