Analyzing Microbial Community Changes of Activated Sludge in Bioaugmentation Reactor by DGGE-PCR

In this study, effluent of 4,5-Diamino-1-pyrazole sulfate were continuously monitored in the a strain L-1 bioaugmented SBR wastewater treatment reactor. It was found that the decolorization rate of the bioaugmented SBR reactor with strain was higher than that of the control, even those under long-time operation in the reactor B whithout adding degrading strain L-1, at the first 2 weeks of almost no degradation during the operation 4,5-Diamino-1-pyrazole sulfate, but a slight increase in degradation rate after 21d. In the reactor A, number of DGGE profiles of activated sludge was found similar bands with L-1 strain's boands.
