Figure 4: Detection of C. saccharolyticus DNA in the reactors after various times when a high organic loading rate was applied, that is, 8 g total organic solids L−1 day−1. PCR was carried out with the the EchA-F1 and EchA-R1 probes. The cellulase-specific celA-F1 and celA-R1 probes corroborated these findings and are therefore not shown.
