The percentage viable and nonviable cells were determined by using a viability probe and an epi- Fluorescence microscope with image analysis. Pediocin PD-1 (3000 AU/mL) removed all cells in a biofilm of O.oeni that formed in acidic grape medium after five hours. Plantaricin 423 (3000 AU/mL) and nisin (3000 AU/mL) killed all viable cells in the biofilm. 收起
