Antifungal effect of the cell-free supernatant (CFS) of Bacillus velezensis CMRP 4489. (a) Evaluation of antifungal activity against Sclerotinia sclerotiorum (SS), Macrophomina phaseolina (MP), and Botrytis cinerea (BC) by metabolites produced in CM1 and CM2 media. (b) Scanning electron microscopy images of the antifungal effect of the CFS against Sclerotinia sclerotiorum. The control refers to the untreated fungal spot and CFS-CM2 refers to the transition area between fungal growth and the inhibition region.
