Figure Lengend Snippet: FIG. 3. Phylogenetic tree showing the position of strain R15 among other species of the genus Methanolobus. Based on a consensus 1,378 bp of the 16S rRNA gene, the tree was constructed by the neighbor- joining method. The topology of the tree was estimated by bootstraps based on 1,000 replications. The number on each branch node is the percentage supported by bootstraps. GenBank accession numbers of 16S rRNA sequences are given in parentheses. Bar, 1% sequence divergence.
