Figure 6.

Unrooted maximum-likelihood tree of isolates belonging to the phylum Firmicutes, shown along with the closest related type strains and other relevant cultured and uncultured bacteria. Phylogenetic analysis is based on the unambiguous alignment (1306 sequence positions) of 16S rRNA gene sequences. GenBank accession numbers are included. Numbers at nodes indicate bootstrap values, based on 1000 replications. Identical isolates based on fingerprinting results (see Supplementary Figure S1) are marked with the same color.
