Fig. 1c shows the more intense inhibition caused by ERY. Inhibition in the intact sludge was 19.7% and 42.6% (acetate and
ethanol respectively) at ERY concentrations of 400 mg L1. For the disrupted sludge, the inhibitory effect increased to 34.2% and 45.7% (acetate and ethanol respectively) at 400 mg L1and intact granules again exhibited higher antimicrobials tolerance
