| Cyanobacteria | 13 | ||||
| Thermotogae | 8 | ||||
| Planctomycetes | 6 | ||||
| Bacteroidetes/Chlorobi | 6 | ||||
| Nitrospirae | 5 | ||||
| Aquificae | 2 | ||||

The taxonomic groups (phyla for Bacteria and Archaea, kingdoms for Eukarya) are grouped by domain and are ordered within each domain based on the number of pathways associated with the taxon. Euglenozoa are listed separately as this group does not belong to any of the other eukaryotic kingdoms. A pathway may be associated with multiple organisms.
