Impedimetric test for rapid determination of performic acid (PFA) biocidal activity toward Echerichia coli

摘要

Background. Performic acid has recently become available on a commercial scale for potential use in waste-water disinfection and can become an innovative biocide for various purposes in food processing. The aim of our study was: 1) to investigate the antimicrobial resistance of performic acid as high active and non toxic chemical disinfectant against Escherichi coli (hygiene indicator test? microorganism used in industrial micro- biology) and 2) to evaluate the electrical impedance measurement method usefulness for fast and high precise test of antibacterial activity.
