Degradation of β-lactam antibiotic ampicillin using sustainable microbial peroxide producing cell system

•Microbial Peroxide Producing Cell assisted degradation of ampicillin was achieved.•Electrochemical production of 36 ± 3.20 to 88 ± 2.90 mM H2O2 was seen.•Microbial electrofenton resulted into in-situ degradation of 96–98% of ampicillin.•Degraded ampicillin was found inactive for sensitivity assay against E.coli.•Simultaneous wastewater-treatment & mitigation of emerging contaminant was done.
