Interactions among filamentous fungi Aspergillus niger, Fusarium verticillioides and Clonostachys rosea: fungal biomass, diversity of secreted metabolites and fumonisin production

Table 6 Interaction-specific metabolic signals obtained from dual cultures of Aspergillus niger (A.n.), Fusarium verticillioides (F.v.), and Clonostachys rosea (C.r.). New metabolites were defined as signals found in dual cultures but not in single cultures
