Inhibitory effect of strains SC3, SC11 and 3-10 and their metabolites on the growth of D. zeae MS2. (A) Inhibitory activities of the SC3, SC11 and 3-10 supernatants (up panel) and 1 µL of overnight cultures (bottom panel) against MS2 growth; (B) Inhibitory activity of SC3 supernatant (SSC3) and its Trypsin enzymatic hydrolysate (SSC3 + Trypsin) against MS2 growth; (C) MS2 (OD600 = 1.5) dilutions respectively grown on the LB agarose, SC3, SC11 and 3-10 metabolite strips; (D) MS2 (OD600 = 1.5) dilutions respectively grown on the LB agarose, and microwave melted SC3, SC11 and 3-10 metabolite strips.
