Data are presented as the percentage of growth compared with the control, and represent the averages of three separate experiments, each with three replicates. The coefficients of variation (V = [s × 100]/X; V, coefficient of variation; s, sd; X, mean) ranged from 2% for the controls to 16% for the treatments in which growth was most strongly inhibited.
