  • White-rot fungus and uses thereof
    Patent number: 5554535
    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.
    Type: Grant
    Filed: October 28, 1994
    Date of Patent: September 10, 1996
    Assignee: Clariant Finance (BVI) Limited
    Inventors: Robert A. Blanchette, Theresa S. Brush, Roberta L. Farrell, Keith A. Krisa, Chittra Mishra

    Assignees: Sandoz Ltd., The Regents of the Univ. of Minnesota
    Inventors: Robert A. Blanchette, Theresa S. Brush, Roberta L. Farrell, Keith A. Krisa, Chittra Mishra
  • Melanin compositions and uses thereof and resulting products
    Patent number: 5538752
    Abstract: Compositions comprising melanin or melanin precursors are useful for preventing or controlling decay of substrates such as cellulosic and other porous organic substrates. The compositions provide useful wood preservatives, wound dressings, and the like. In one embodiment, the compositions comprise melanin complexed with metal ions, particularly copper. The compositions may be applied as penetrating or surface treatments. Certain melanins are also particularly useful for removing metal ions from liquids.
