The effects of AMQD4 on the degradation and microbial biomass in gentamicin sewage (SSWA, sterilized sewage without AMQD4; SSA, sterilized sewage +2.5% AMQD4; USWA, unsterilized sewage without AMQD4; (4) USA, unsterilized sewage +2.5% AMQD4). The mean values and SD (error bars) from triplicate trials are presented. Data bars having the same letter are not significantly different from each other at the 95% confidence level in the Duncan’s test (P < 0.05).
