Analysis of aerobic granules under the toxic effect of ampicillin in sequencing batch reactors: Performance and microbial community
To study the change of the aerobic granules' microbial community in the present of antibiotics, ampicillin (AMP) was selected as a model component. With acetate as carbon source, different concentrations of AMP (5, 10 and 15 mg L.sup.-1) were applied to the inflow intermittently and the results showed that the stability of the aerobic granules was maintained below 10 mg L.sup.-1 AMP. Simultaneously, under exposure to 5 and 10 mg L.sup.-1 AMP, the COD removal efficiency in the batch reactors remained at 86% and AMP was degraded almost completely with a removal efficiency of 97%. However, the EPS concentration and dehydrogenase activity decreased constantly with increasing AMP dosage.
