Autotrophic Nitrogen Removal

PCR-DGGE was applied to analyze the relationship between pH and the microbial community structure of Sequence Batch Biofilm Reactor (SBBR) autotrophic nitrogen removal process. The reactor was possessed of a high nitrogen removal efficiency at pH=8.0 where the similarity of microbial community structure between active sludge and biofilm samples was the lowest about 84.6% and the richness of bacterial community was the most abundant in biofilm compared with other pH conditions. pH=7.0 was good for the microbes in active sludge but unfavorable for anaerobic bacteria. At pH=9.0, the effects were presented with both bacterial activities and microbial community structure and when pH=6.0 the amount of microbial types dramatically dropped
