Figure 2

Phylogenetic tree based on DNA sequences of 16S rRNA gene using neighbor-joining method. Klebsiella sp. strain FH-1 is shown in bold. Belliella pelovolcani is used as the outgroup. GenBank accession numbers are given in parentheses following the species names. Bootstrap values based on 1000 replicates are given next to the branches. The bar indicates 0.020 base difference per nucleotide position.
