Figure 2.

The antifungal activity of the cell-free filtrate of the antagonistic bacterial strains against Fusarium oxysporum f. sp. nevium (Fon). (A) Fon colonies were grown on potato dextrose agar supplemented with the cell-free filtrate of the antagonistic bacterial strains or with sterile Luria-Bertani medium as controls. (B) The inhibition rate (%) for the cell-free filtrate of the bacterial antagonists against Fon. The results in (A) are from an experiment that was performed independently three times with similar results. The data presented in (B) are the means ± standard deviation from three independent experiments. Different letters above the columns indicate significant differences at the p-value < 0.05 level according to the one-way the analysis of variance test.
