  • Aspergillus niger which produces vanillic acid from ferulic acid
    Patent number: 6162637
    Abstract: Method for the production of vanillic acid and vanillin by bioconversion from ferulic acid in a medium containing phospholipids cultured with at least one microorganism from the classes Ascomycetes, Basidiomycetes or Actinomycetes. Vanillin is also produced by bioconversion of vanillic acid by at least one microorganism of the class Basidiomycetes in a medium containing cellobiose.
    Type: Grant
    Filed: December 18, 1998
    Date of Patent: December 19, 2000
    Assignee: Institut National de la Recherche Agronomique - I.N.R.A.
    Inventors: Laurence Lesage-Meessen, Michel Delattre, Mireille Haon, Marcel Asther

  • Filamentous fungus proteins for binding and transporting lipids, method for preparing them and their applications
    Patent number: 5717070
    Abstract: The present invention is directed to a family of phospholipid binding and transporting proteins, a method for preparing same from fungi, and their use in cosmeticology, the agri-foodstuffs industry and pharmacology Phospholipid proteins are capable of binding, transporting and/or rearranging lipids between membranes, optionally in combination with active principles. Furthermore, the phospholipid proteins are hydrophobic and acidic, have a molecular weight of under 50 kDa, and may be prepared from a non-toxic filamentous fungus capable of developing on a lipid-enriched medium, particularly from raw extracts of fungi.
