When applied within a low-strength electric field (+/- 12 V/cm) with a low current density (+/- 2.1 mA/cm2), several industrial biocides exhibited enhanced killing action against Pseudomonas aeruginosa biofilms grown on stainless steel studs. Biocide concentrations lower than those necessary to kill planktonic cells of P. aeruginosa (1, 5, and 10 ppm of the active ingredients of kathon, glutaraldehyde, and quaternary ammonium compound, respectively) were bactericidal within 24 h when applied within our electrified device.
当在低电流密度（±2.1 mA/cm²）的低强度电场（±12 V/cm）中应用时，几种工业杀菌剂对生长在不锈钢柱上的铜绿假单胞菌生物膜表现出增强的杀灭作用。当在我们的带电装置中应用时，低于杀灭铜绿假单胞菌浮游细胞所需浓度（卡松、戊二醛和季铵化合物的活性成分分别为1、5和10 ppm）的杀菌剂在24小时内具有杀菌作用。
