Composition containing strains of Ophiostoma piliferum and a method of using the composition to reduce the pitch content of pulpwood or pulp |
摘要 |
Ascospores of wood-penetrating, pitch-grading fungi of the class of Ascomycotina and Deuteromycotina, e.g. Ophiostromas, may be screened to provide fungi combining the properties of good growth on non-sterile wood substrates and minimized or even enhanced brightness effects for use in pitch reduction of wood substrates, e.g. logs and wood chips. A new and improved method of isolating such ascospores involving effective suspension in an oil consumable by the fungus, e.g. a vegetable oil, and then treatment of the oil with a dispersing agent is also disclosed.
