Microbial Community Structures in Two Membrane Bioreactors: Sequential and continuous modes

摘要：

A sequential membrane reactor (SMBR) and a continuous membrane reactor (CMBR) were developed with focus on reactor performance and microbial community structure. The two MBRs all showed better removal of chemical oxygen demand (COD) and ammonia-nitrogen (NH4+-N) treating synthetic wastewater, but the SMBR system showed markedly low membrane fouling rate because of sufficient relaxation of membranes. The results of denaturing gradient gel electrophoresis (DGGE) demonstrated the diversity of total bacteria and and β-proteobacteria ammonia-oxidizing bacteria (β-AOB) in CMBR was more complex than that of SMBR. Real-time PCR analysis indicated the number of β-AOB in CMBR was larger than that of SMBR, which resulted in high NH4+-N removal.
