The cultivation broth consisted of Potato Dextrose Broth (PDB), Difco (Potato Starch 4 g/L, Dextrose 20 g/L), completed with 30 g/L of XAD-16 resin. The Potato Dextrose Agar (PDA) consisted of PDB supplemented with agar at a final concentration of 20%. Prior to the cultivation step, Petri dishes were inoculated with a frozen mycelium sample for 5 days. Four milliliters of medium were then spread on the agar layer and scratched. The spores-mycelium mixture was used to inoculate 10 2 L Erlenmeyers containing 1 L of PDB medium. The strain was then allowed to grow 5 days in a rotary shaker at 27 C and 150 rpm. At the end of the incubation period, resin was recovered by filtration and separated from residual mycelium by decantation.
