FIG. 2.

Monitoring the decomposition of BOA to HPMA using TLC. TLC profiles for F. verticillioides strains MRC 826 and NRRL 25059 are shown. Cultures were grown on PDA amended with either 0.5 or 1.0 mg of BOA per ml (see Materials and Methods). Agar plugs were taken from three regions of a 7- to 15-day-old culture and spotted onto the TLC sheet as indicated (mp, margin of plate; mc, margin of colony; and wc, within colony). The sheet was developed in toluene-ethyl acetate-formic acid (50:40:10), and the top of the image corresponds to the solvent front.
