16S rRNA gene neighbor-joining tree showing relationship of representative sequences from SIP-derived OTUs in this study (in bold) to nearest relatives. The total number of clones represented by each sequence is indicated in brackets. GenBank accession numbers are displayed in parentheses. A sequence representing AG1 from SIP of the untreated soil is underlined. The tree was bootstrapped 1,000 times and circles at nodes indicate either ≥95% (open circles) or ≥50% (closed circles) bootstrap support. The 16S rRNA gene sequence of Mycobacterium vanbaalenii was used as an outgroup. OTUs, operational taxonomic units; SIP, stable-isotope probing.
