  • Patent number: 4942032
    Abstract: A method for producing a novel antifungal product from a Pediococcus species is described. The preferred product (AFP) comprises a compound which contains valine and lactic acid and has a molecular weight of less than about 500 daltons. The product (AFP) is particularly useful in retarding fungal growth in foods and other materials in need thereof.
    Type: Grant

    Assignee: Microlife Technics, Inc.
    Inventors: Peter A. Vandenbergh, Blair S. Kunka
  • Patent number: 4933191
    Abstract: A novel dextran having a slushy, applesauce-like appearance with a particulate gel-like structure in crude form is described. The dextran is particularly produced by Leuconostoc dextranicum NRRL-B-18242. The dextran in particulate or dried form is used in foods and other applications where texture is important.

  • Patent number: 4877634
    Abstract: Novel dried compositions containing polysaccharides (dextrans and levans) derived using a Leuconostoc to ferment sucrose to produce the polysaccharides are described. In particular, dried compositions incorporating milk solids or other drying aids to facilitate drying and rehydration of the polysaccharides are described. The compositions are useful as quality (e.g. texture, stability or thickness) improvers for foods.

  • Patent number: 4853334
    Abstract: A process for degrading volatile halogenated aliphatic hydrocarbons containing 1 to 3 carbon atoms using Pseudomonas fluorescens NRRL-B-18296 is described. The method preferably uses a carbon source, such as glucose or molasses, which stimulates the bacterium to degrade the hydrocarbons and which is readily degraded in the environment so that the halogenated aliphatic hydrocarbon is degraded to carbon dioxide, water and hydrochloric acid so that no toxic residues are produced.
