FIG. 3.

Rooted neighbor-joining phylogenetic tree of partial 16S rRNA gene sequences of clones that were recovered from wild sponges (prefixed W04ML, shown in blue) collected at the same time as 1-month-aquacultured sponges (prefixed 1m04AML, shown in green) from the recirculating aquaculture system. Bootstrap confidence values of >50% are shown at the nodes. The tree was constructed using ARB. The tetragons represent clones that are >99.5% similar (see Table S2 in the supplemental material); the numbers listed in bold before the group names indicate the numbers of clones. Thermatoga maritima was used as the outgroup in the analysis. Scale bar indicates 0.10 substitutions per nucleotide position. Reference sequences are shown with GenBank accession numbers listed after each sequence name. Major bacterial groups found in both libraries are indicated in bold on the right-hand side of the tree.
