Bactericidal activity of a phage mixture in pasteurized milk with standard deviations. The mean germ density (log10 cfu/mL) of the two S. aureus isolates 7142 and 10614, respectively, for the control culture without phages (blue: 7142; orange: 10614), the assays with the addition of 0.1 mL phage mixture at a final concentration of 1.2 × 108 pfu/mL (grey: 7142; violet:10614) and 1 mL phage mixture at a final concentration of 1.2 × 109 pfu/mL (yellow: 7142; green: 10614). Inoculation with S. aureus at a concentration of averagely 1.1 × 105 cfu/mL. Dilution series were limited at 3.0 × 106 cfu/mL for the investigation in pasteurized milk.
