|a The influence of different target pollutants and operation modes in sequencing batch bioreactors (SBRs) on sludge toxicity was compared in this study. Sludge toxicity was characterized by the inhibiting luminosity through using luminescent bacterium Photobacterium phosphoreum (P. phosphoreum) during either gradual acclimation or impaction processes with synthetic wastewater containing high-strength bisphenol A (BPA) or N, N-dimethylformamide (DMF). When the activated sludge was first acclimated with either 120 mg/L DMF or 20 mg/L BPA, and then respectively increased to 200 mg/L DMF and 40 mg/L BPA it was defined as gradual acclimation process, whereas when the activated sludge was, respectively, injected with 200 mg/L DMF and 40 mg/L BPA directly it was defined as impaction process. Results showed that the toxicity of the impacted sludge was greater than that of the gradual acclimated sludge, especially in the initial stage before 10 d. Activated sludge treating BPA synthetic wastewater exhibited higher toxicity due to the more inhibition of BPA to sludge activity compared to that of DMF. The proteomics analysis indicated that the stress responses of activated sludge to DMF and BPA stimulation were both significant. In turn, the secretions from two kinds of sludge under stress conditions contributed to sludge toxicity
