Trametes versicolor

and Schizophyllum commune). The third species was the brown-rot fungi Antrodia vaillantii, using three different strains of this species. Antrodia vaillantii substantially decreased the pH-value of impregnated and unimpregnated wood before any mass loss appeared. On the other hand, the white-rot fungus T. versicolor and S. commune caused a slight increase of the pH of impregnated and unimpregnated wood. It is suggested that a decrease of pH of wood may indicate early stages of decay by brown rot fungi.

Trametes versicolor

und Schizophyllum commune). Die dritte Art war vom Braunfäuletyp (Antrodia vaillantii), wovon drei verschiedene Stämme eingesetzt wurden. Antrodia vaillantii senkte den pH deutlich in imprägnierten und unbehandelten Proben, noch bevor ein Massenverlust auftrat. Die beiden Weissfäuleerreger T. versicolor und Sch. commune ließen den pH dagegen ansteigen. Anhand des pH-Abfalls konnte man schon frühe Stadien eines Braunfäuleabbaus erkennen.
