Biological Control of Blue Stain in Pulpwood: Mechanisms of Control used by Phlebiopsis gigantea

摘要

Phlebiopsis gigantea, a white-rot fungus currently being tested in biological processing applications for the pulp and paper industry, was shown to effectively inhibit blue stain fungi in both laboratory and field trials. Inoculation of logs with P, gigantea shortly after cutting resulted in up to 86/100 colonization of logs in the laboratory and 100/100 in field studies. Colonization of logs by blue stain fungi such as Ophios- toma piliferum and O. piceae was greatly reduced or completely inhibited with prior inoculation by P. gigantea.
