DNA was extracted using the MagNA Pure LC DNA Isolation Kit III (bacteria, fungi) (Roche Diagnostics, Mannheim, Germany). Fungal mycelium with a surface area of 2-4 cm2 was obtained, added to phosphate buffered saline, and samples were prepared according to the manufacturer's recommendations. Briefly, approximately 100 µL of sample was mixed with 130 µL of bacterial lysis buffer and 20 µL of proteinase K, incubated at 95℃ for 10 min and then cooled. After sample preparation DNA was isolated using magnetic-bead technology, according to the manufacturer's instructions.
