Abstrakt: Protease activities from 10 homokaryotic isolates of Heterobasidion annosum, two isolates of Grern-rneniella abietina and six isolates of Endocronartium pini were studied. All the fungi showed in vitro protease activity with denatured casein. The greatest caseinolytic activity was at acidic pH, but Heterobasidion annosum and Gremrneniella abietina showed caseinolytic activity at basic pH also. Protease preparations from Heterobasidion annosurn were able to degrade proteins from total phloem extracts of Pinus sylvestris, Picea abies, Betula pendula and Juniperus cornmunis.
