摘要：
DC corona discharges in air were tested for the eradication of 48-hour Escherichia coli biofilms on glass slides. Thermostatic cultivation and confocal laser scanning microscopy of the biofilm stained with fluorescent dyes were used for biocidal efficiency quantification. Up to 5.7 log(10) reduction of bacterial concentration in the biofilm was measured after exposure to DC corona discharges for 15 min. CLSM showed that live/dead ratio in the biofilm was decreasing after plasma treatment and that the biofilm thickness was reduced for both corona polarities. The biofilm biomass loss was supported by crystal violet assay.
