  • Somatic hybrids of Rutaceae plants
    Patent number: 4940836
    Abstract: Somatic hybrids of Rutaceae plants were obtained by allowing the protoplasts from embryogenic cells of a Rutaceae plant, which are of the nucellar origin, resistant to fusion treatment, and have a high proliferation activity, to fuse with the protoplasts of another Rutaceae plant having no proliferation activity, and then cultivating the fused protoplasts in a medium not containing a phytohormone but containing a saccharide in a concentration suitable for the selective embryogenesis of the hybrid cells.
    Type: Grant

  • Novel pectin esterase, process for its production, and process for producing demethoxylated pectin by the use of said pectin esterase
    Patent number: 4200694
    Abstract: A novel pectin esterase which randomly hydrolyzes the methyl ester bond of pectin can be obtained by cultivating, on a medium, a mold strain belonging to Genus Aspergillus, Genus Penicillium, Genus Fusarium or Genus Sclerotinia and having an ability to produce said novel pectin esterase. A demethoxylated pectin having a uniform methoxyl group content can be obtained by adding said novel pectin esterase to pectin. The demethoxylated pectin thus obtained can be utilized as gelling agent, emulsifier or thickener for food processing.
