Table 4 Suppression of secreted metabolites in dual cultures of Aspergillus niger (A.n.), Fusarium verticillioides (F.v.), and Clonostachys rosea (C.r.). Suppressed metabolites were defined as metabolites with normalized signal intensities in dual cultures at least 10-times lower as compared to single cultures. Metabolites transformed or catabolized by interacting species were not included
