Effects of monoterpenes on Fomes annosus (Fr.) Cooke and its phenol oxidase activity

Fomes annosus was cultivated subject to vapours of monoterpenes. Three monoterpenes were tested separately: α-pinene, β-pinene and 3-carene. The terpenes inhibited the dry matter production of the fungus but extracellular phenol oxidase activity was increased, particularly when the fungus was exposed to vapours of β-pinene and 3-carene.
