Phylogenetic tree based on 16S rRNA gene sequences from Kam1 and representatives from the Verrucomicrobia phylum. Sequences were retrieved from the Ribosome Database (http://rdp.cme.msu.edu), and the Kam1 sequence was added to this alignment. The tree was constructed by using the neighbor-joining algorithm with the Kimura two-parameter correction based on 1,211 positions. Nodes supported by bootstrap values >50% after 100 resamplings of neighbor-joining, and maximum-likelihood (in brackets) analyses are indicated. The 16S rRNA gene sequence of Methylococcus capsulatus was used as an outgroup. Subdivisions are indicated by encircled numbers. The scale bar represents 0.1 nucleotide changes per position.
