Gum Guaiac in Field Tests for Extracellular Phenol Oxidases, of Wood-Rotting Fungi and Other Basidiomycetes.
Abstract
One hundred ninety-two species of Basidiomycetes, mostly wood-decaying or wood-inhabiting, were tested in the field with gum guaiac reagent to determine if extracellular phenol oxidases were present. Of these, 79 gave negative reactions; 113, positive. Of those with positive reactions, 110 are white rot fungi; three species (Phaeolus schweinitizii (Fr) Pat., Tyromyces Fragilis (Fr.) Donk, and T. sub cartilagineus (Overh.) Dom.) that gave a positive reaction are brown-rot fungi. In field tests a negative reaction did not relate as conclusively; 38 white-rot fungi failed to give a positive test. (Author)
