Fig. 4. Neighbor-joining phylogenetic tree based on 16S rRNA gene sequences showing the relationship between the strains isolated in this study and their closest relatives of the class Betaproteobacteria. The tree was reconstructed using neighbor joining (NJ), maximum likelihood (ML), and maximum parsimony (MP) algorithms. Filled circles indicate corresponding branches present in the phylogenetic tree generated using the three different tree construction methods. Bootstrap values (expressed as percentages of 1000 replications) of above 70% are shown at branch points. Bar, 0.02 substitutions per nucleotide position.
