International Classification:

C12N 114
C12P 102
C02F 300

US Classification:

4352541

Abstract:

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.

Appl. No.:

8/646668

Assignee:

Clariant Finance (BVI) Limited - Tortola

International Classification:

C12N 114

US Classification:

4352533

Abstract:

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.

International Classification:

D21C 500
D21C 908
C12N 114
C12P 102

US Classification:

435278

Abstract:

The present invention relates to the use of certain fungi in the reduction of the pitch and/or lignin content of cellulosic materials. In particular, the white rot fungi Schizophyllum commune, Trichaptum biforme and Phanerochaete gigantea are useful in reducing pitch and/or lignin, or both, which saves electrical energy during the mechanical refining of pulps and pulpwoods used in making cellulosic products.
