FIG. 3.

Phylogenetic analysis of bacterial 16S rRNA gene fragments ca. 600 to 620 bp in length from enrichments originating from A. caliginosa and L. terrestris. The tree was constructed by the neighbor-joining method. Clones sequenced in this work are in bold. Sequences with identities of >99.5% were taken as belonging to a single OTU and are shown as one ID number. Values in parentheses are numbers of clones. Numbers at nodes are bootstrap values greater than 50% and were calculated by the Kimura two-parameter, maximum-likelihood, and Bayesian treeing methods, respectively; branching topologies that are not supported by either method are marked by a dash at the corresponding node.
