Fig. 5.
Neighbor-joining tree based on the alignment of approx. 750 bp 16S rRNA gene sequences of proteobacterial clones. Abbreviations for sampled year (deposit age, y) of clones: OY04, 2004 (3.5); OY05, 2005 (5.0); OY07, 2007 (6.6). After the representative clone, the number of similar sequences (based on a 1% cutoff) is given in parentheses. Bootstrap values from 50% to 75% and >75% are indicated by open and solid circles at the branches, respectively. Scale bar shows 0.02 substitutions per site. Acidobacterium capsulatum JCM7670T was used as an out-group for the dendrogram.
