Abstract:
This study aimed to evaluate the effects of quinoline on nitrogen removal performance and microbial community of an anaerobic biofilm reactor with anammox activity. Results showed that 20 mg L-1 quinoline addition leading the ammonia and nitrite removal efficiency of the ABR reduced from about 90% to 40%. Illumina MiSeq sequencing study indicated that microbial community structure and composition varied with the additive of quinoline. Planctomycetes and Bacteroidetes, decreased in abundance, suggested that quinoline adversely affects the anammox metabolism within the anammox reactor. The distribution of the anammox bacteria was affected by quinoline addition. Ca. Jettenia prevailed over the other two anammox bacteria (Brodica and Kuenenia) in the recovered phase.
