  1. *Mutants observed after 24 h. 5 μl of each bacteriocin at 1 mg/ml was used in the spot-on-lown assay. Average Inhibition score (n = 3) indicates: “−” = No inhibition; “+” = Unclear zone; “++” = zone < 1 cm, and “+++” = zone ≥ 1 cm.
  2. **Strains where H1 resistant mutants where isolated from 1 mg/ml spot-on-lawn inhibition zone.
