Ribosomal protein-based tree of the members of Peptostreptococcaceae. A maximum-likelihood tree was built using the PhyML program (Guindon et al., 2010) from a concatenated alignment of 50 ribosomal proteins (L1–L7, L9–L11, L13–L24, L27–L29, L31–L36 and S2–S20), with a total of 6269 aligned positions, as described previously (Yutin et al., 2012; Yutin & Galperin, 2013). The organisms proposed for renaming are indicated in boldtype. The names of the organisms that have not been validly published are in quotation marks. The tree was rooted using sequences from C. butyricum and C. botulinum.
