Phylogenomic position of the 5 Desulfuromonas spp. strains in the reconstructed maximum likelihood (ML) tree based on the concatenated amino acid sequences deduced from 371 single-copy housekeeping genes. The branch length shows genetic distance with 1000 bootstrap replicates. Blue color font shows the anode-stimulated strains in the order Desulfuromonadales. Bold and normal fonts show the complete and incomplete genome sequences, respectively, of the strains. Number in brackets shows the count of deduced multiheme c-type cytochrome in the genomes. Pink circle shows the strain that had no gene cluster for flagellum biosynthesis, and the red, black and blue stars show the strains stimulated by using the crystalline Fe (III) oxide, elemental sulfur and anode as the electron acceptors, respectively
