Epsilonproteobacteria phylogenetic tree. Neighbor-joining trees were constructed from aligned, full-length clone 16S rRNA sequences of OTUs detected more than once, based on 1,197 homologous positions filtered by base frequency (50%) using MEGA6. Tag sequences that were identical to a clone sequence were identified. Bootstrap values were calculated in MEGA6, and nodes with >50% support, based on 1,000 replicates are displayed. Hydrogenobacter hydrogenophilus (Z30242) and Thermosulfidicus takaii (AB282756) were used as outgroups.
