Abstract

In this study, the antifungal activity of cell-free supernatant (CFS) of Lactobacillus spp. (Lactobacillus plantarum CCM 1904; L81, Lactobacillus fermentum; 2I3, Lactobacilus reuteri; 2/6, L26;) and Bacillus spp. (Bacillus subtilis CCM 2794, Bacillus licheniformis CCM 2206) against two strains of Fusarium graminearum CCM F-683 and Fusarium graminearum CCM 8244 were investigated in vitro. All tested CFS of Lactobacillus spp. were able to inhibit the growth of both strains of Fusarium graminearum. The highest inhibitory effect (IE) (56.5 %) against F. graminearum CCM F-683 was observed for CFS Lactobacillus fermentum (2I3) at the minimum inhibitory concentration (MIC) (2.25 ± 0.56 mg.ml–1). CFS of Lactobacillus reuteri (2/6) showed the best IE (40.0 %) against F. graminearum CCM 8244 (2/6) at the MIC 1.25 mg.ml–1. However, no inhibitory effect of Bacillus subtilis and Bacillus licheniformis CFS against both strains of F. graminearum were observed, even at the highest tested concentration of 5.0 mg.ml–1.
