Summary: In the present work, 11 bacteria previously identified as fungal pathogen antagonist were used. For the chemical characterization of potential antifungal metabolites, a screening was first performed through co-cultures to identify the best antagonists against seven agricultural pathogens. Of the 77 combinations tested, at least 44 (57%) showed potential antagonism, especially CMAA1398 and CMAA1399, inhibiting all tested fungi strains. Now, the CMAA1399 extract is under characterization by MS.
