^aOne-milliliter samples of phage tail-like bacteriocin suspensions in TY broth were mixed with stock trypsin solutions (in H₂O) in prewarmed Eppendorf tubes and incubated at 37°C. Samples were serially diluted (2⁻¹ to 2⁻⁸) with TY broth, and drops of all dilutions were placed on agar plates (1.5% [wt/vol] nutrient agar no. 2; Imuna, Slovakia) overlaid with a corresponding indicator strain in soft agar 0.7% (wt/vol). AU, arbitrary units.
