Biotransformation of secreted fungal metabolites by mycelium of a different fungus. Ethyl acetate extracts of supernatants of 10 and 20 days old culture of one species were incubated with mycelium of a second species to determine whether the metabolites of one fungus can be transformed by another fungus. The resulting metabolic profiles were subjected to cluster analysis by UPGMA using Jaccard’s similarity coefficients (coph. coeff = 0.944). Nodes denoted as ■ were supported by >75 % bootstraps for 2000 replicates. A_Mycel, F_Mycel, G_Mycel: metabolic profiles of supernatants of washed mycelium of Aspergillus niger (A.n.), Fusarium verticillioides (F.v.), Clonostachys rosea (C.r.), respectively; A_Meta, F_Meta, G_Meta: metabolic profiles of supernatants of single cultures A.n., F.v., and C.r., respectively; X_Mycel + Y_Meta: metabolic profile of the supernatant after incubation of mycelium X with metabolites extracted from supernatant of Y
