Abstract Three sequencing batch reactors (SBRs) were
operated in parallel to study the effects of trace erythromy-
cin (ERY) and ERY-H2O on the treatment of a synthetic
wastewater. Through monitoring (1) daily effluents and (2)
concentrations of nitrogen (N) and phosphorous (P) in
certain batch cycles of the three reactors operated from
transient to steady states, the removal of carbon, N, and P
was affected negligibly by ERY (100g/L) or ERY-H2O
(50g/L) when compared with the control reactor. Howev-
er, through analyzing microbial communities of the three
steady state SBRs on high-density microarrays (Phylo-
