Figure 4. Analysis of the DGGE profiles of the different reactors on days 0, 2，and 8，using partial bacterial 16S rRNA gene fragments, based on DNA and RNA. The gene fragments were obtained by using an AOB-specific PCR with primers CTOl89AB. CT0189C. and CT0653r (Table 1), followed by a second PCR with bacterial primers P338F and P5l8r (Table 1). Bands 3，4. and 5 were excised and sequenc'd for further analysis. Lanes: 1, reactors without inoculate and without 3.CA shock; 2. nonbioaugmented reactors with 3. CA shock load; 3. bioaugmented reactors with 3-CA shock load. The accession numbers of the most similar sequencecs in GenBank are mentioned in the text
