Figure 1. Phylogenetic relationship between the 16S rRNA gene sequences from the soil isolates with high Mn(II)-oxidizing activities (labeled with “□”) and their closest GenBank sequences with 16S rRNA gene from the known Mn(II)-oxidizing bacterial strains (labeled with “▪”) reported previously.

The GenBank accession numbers of these sequences are shown in brackets. Bootstrap values ≥50% with 1,000 replicates are indicated at the branch points.
