Table 5 Secreted metabolites stimulated in dual cultures of Aspergillus niger (A.n.), Fusarium verticillioides (F.v.), and Clonostachys rosea (C.r.). Induced metabolites were defined as metabolites with normalized signal intensities at least 10-times larger in dual cultures as compared to single cultures
