FIGURE 4.
Growth inhibition assays in the presence of nisin A and the nisin H varants. The lantibiotic nisin A (black bars), the heterologous expressed nisin H (red bars) and the position 1 variant of nisin H F1I (blue bars) were used for growth inhibition (IC50) with the strains NZ9000Cm, NZ9000NisI, NZ9000NisFEG, NZ9000SaNSR, and NZ9000SaNsrFP. Values represent the average of at least five biological independent measurements and the errors report the standard deviation of the mean (SDM).
