Phylogenetic relationship of the strain D25 and related taxa, based on 16s rDNA analysis. The evolutionary history was inferred using the Neighbor-Joining method [18]. The optimal tree with the sum of branch length = 0.19907131 is shown. The percentage of replicate trees in which the associated taxa clustered together in the bootstrap test (100 replicates) is shown next to the branches [19]. The evolutionary distances were computed using the p-distance method and are in the units of the number of base differences per site. The analysis involved 20 nucleotide sequences. All ambiguous positions were removed for each sequence pair. There were a total of 1574 positions in the final dataset. Evolutionary analyses were conducted in MEGA5 [14].
