3.1.4. Assessment of Fungal Activity

Using previously prepared test cultures of Coniophora puteana, the fungal activity of the specimens was verified. Specimens of Scots pine wood (15 × 25 × 50 mm) were placed in Kolle flasks on medium covered by the mycelium. The flasks were stored in an incubating chamber at 22 ◦C and 70% humidity for 16 weeks. After removal of the mycelium, the wood specimens were weighed and the mass loss was determined. It was confirmed that they achieved the required loss in mass over 20%.
