Phylogenetic neighbor-joining tree constructed on the basis of analysis of the 16S rRNA gene sequences of Archaea revealed in the DNA-derived clone library of formation water from near-bottom zone of injection well 1098-8 m3 sampled in December 2006 from the Kongdian bed. Designation: DA means DNA-based library of Archaea clones (115 clones). Scale bars show five (0.05) nucleotide substitution per 100 nucleotide base pairs. The numerals at the branching points show the significance of the branching order as determined by bootstrap analysis of 100 alternative trees (only bootstrap values above 85% were considered significant).
