Phylogenetic tree of selected Methanomicrobiales showing the distance between the three organisms for which complete genomes are available — Methanospirillum hungatei, Methanocorpusculum labreanum, and Methanoculleus marisnigri. The tree uses 16S ribosomal RNA sequences aligned within the Ribosomal Database Project (RDP), and the tree was constructed with the RDP Tree Builder [5]. Methanosarcina barkeri was used as the outgroup. The numbers on the branches represent bootstrap values based on 100 replicates.
