摘要： Ascospores of wood-penetrating, pitch-grading fungi of the class of Ascomycotina and Deuteromycotina, eg. 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, eg. logs and wood chips. A new and improved method of isolating such ascospores involving effective suspension in an oil consumable by the fungus, eg. a vegetable oil, and then treatment of the oil with a dispersing agent is also disclosed.

摘要： The bacteria Pseudomonas fluorescens and Xanthomonas campestris are useful in reducing the pitch content of pulps and pulpwoods used in making cellulosic products. Such bacteria are also useful in reducing the color staining by staining fungi of structural wood by inoculating the structural wood or log sources from which it is to be cut.

摘要： This invention relates to fungi having particularly desirable overall properties for reducing the pitch content of pulpwoods and pulps, and to the preparation and use of such fungi. In particular, the present invention provides a biologically pure cultures of the fungus Ophiostoma piliferum which are characterized by not only growing white or colorless and by having good growth virulence, but which also exhibit exceptional pitch degradation properties.

摘要： The white rot fungus Scytinostroma galactinum strain F361 and mutants thereof are particularly effective in selectively grading the lignin component of lignin-containing materials, particularly processed wood pulps including chemical pulps, and also particularly effective in degrading lignin degradation products such as chlorinated degraded lignin by-products as found, for example, in E-1 effluents, and also in degrading chlorine-containing aromatic compounds generally as found in aqueous waste streams containing the same.

摘要： The subject invention concerns a novel enzymatic process for bleaching kraft pulp. Specifically, novel enzymes, designated rLDM.TM., and other ligninolytic enzymes present in the extracellular growth medium from a fermentation of Phanerochaete chrysosporium, are used to bleach kraft pulp to a desired lighter color.

摘要： The bacteria Pseudomonas fluorescens, Pantoea (Enterobacter) agglomerans, Bacillus cereus, and Xanthomonas campestris are useful in reducing the pitch content of pulps and pulpwoods used in making cellulosic products. Such bacteria are also useful in reducing the color staining by staining fungi of structural wood by inoculating the structural wood or log sources from which it is to be cut.
