Abstract
Evernia prunastri Ach., an epiphytic lichen growing on Quercus rotundifolia Lam., produces a β-1,4-glucanase (EC 3.2.1.4) and a polygalacturonase (EC 3.2.1.15). The activity of these polysaccharidases increases as a response to incubation of the lichen with carboxymethylcellulose or sodium polygalacturonate, respectively. This increase in activity is thought to be the result of enzyme induction because it is inhibited by both cycloheximide and 8-azaguanine. Both polysaccharide-degrading enzymes are partially secreted into the incubation media.
