摘要: 

Inactivation and microbial regrowth of penicillin-,ampicillin-,cefalexin-,tetracycline-,chloramphenicol-,and rifampicin-resistant bacteria were studied to explore risks associated with selection and regrowth of antibiotic-resistant bacteria after PAA disinfection.The results showed that after exposure to 20 mg/L PAA for 10 min,inactivation of ampicillin-resistant bacteria reached 2.3-log,which was significantly higher than that of total heterotrophic bacteria with a decrease of 2.0-log.In contrast,inactivation of tetracyclineresistant bacteria was significantly less efficient,reaching only 1.1-log.Chloramphenicol-and tetracycline-resistant bacteria,as well as total heterotrophic bacteria regrew more than 10 fold compared to those in the untreated wastewater sample with 22 h stilling culture after exposure to 2 or 5 mg/L PAA as for 10 min.Selection and potential regrowth of tetracycline-and chloramphenicol-resistant bacteria are potential risks when utilizing PAA disinfection,which may induce the spread of specific antibiotic-resistant bacteria in reclaimed water.
