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

Table 7 Secreted fungal metabolites transformed by another fungus. Ethyl acetate extract of culture supernatant of fungus labeled as metabolite producer was incubated with washed mycelium of another fungus and the number of metabolic signals that disappeared was counted
