The profile of 16S rDNA PCR-DGGE for (a) bacteria and (c) archaea in Hf-MBfR.

<p>The line number indicates the sampling hour and ‘M’ represents a marker. This neighbor-joining tree shows the relationships between representative sequences and their related strains (b, bacteria; d, archaea). <i>Escherichia coli</i> K12 (CP009685) and <i>Sulfolobus acidocaldarius</i> DSM 639T (CP000077) were used as the outgroup for bacteria and archaea, respectively. Scale bar: 0.02 nucleotide substitutions per position for bacteria and 0.05 for archaea.</p>
