FIG. 4.

Kinetics of growth, EH activities, and AAL toxin production by A. alternata f. sp. lycopersici grown in petri dishes containing 30 ml of medium with glucose as the carbon source and with (■) or without (●) 1 mM clofibrate. Clofibrate was added on the 2nd day of culture (arrow). A. alternata (black mold) (▾) was grown under the same conditions without any clofibrate added. (A) Fungal biomass; (B) EH specific activity with t-DPPO as a substrate; (C) concentration of AAL toxin expressed as TA equivalents.
