  • Patent number: 5707833
    Abstract: This invention relates to a .gamma.-cyclodextrin glucanotransferase having novel properties, to a process for the production of the .gamma.-cyclodextrin glucanotransferase which comprises culturing a strain belonging to the genus Brevibacterium capable of producing cyclodextrin glucanotransferase, thereby allowing the strain to produce the .gamma.-cyclodextrin glucanotransferase in a culture medium, and subsequently collecting the enzyme, to a process for the production of cyclodextrin which comprises allowing the cyclodextrin glucanotransferase to react with substrate dissolved in a solution, thereby effecting formation of .gamma.-cyclodextrin as a main product, and to a method for increasing .gamma.-cyclodextrin yield without accompanying yield increase of total cyclodextrin, which comprises adding ethyl alcohol to a reaction solution in which .gamma.-cyclodextrin and .beta.-cyclodextrin are formed from starch by the action of .gamma.

    Date of Patent: January 13, 1998
    Assignee: Amano Pharmaceutical Co., Ltd.
    Inventors: Shigeharu Mori, Tamio Mase, Takaichi Ohya
  • Patent number: 5270188
    Abstract: A glyceride produce free from triglycerides and containing mostly monoglycerides is made by mixing glycerol and fatty acids with a lipase which is isolated from Penicillium cyclopium ATCC 34613.
    Type: Grant
    Filed: November 12, 1991
    Date of Patent: December 14, 1993
    Assignee: Amano Pharmaceutical Co., Ltd.
    Inventors: Shotaro Yamaguchi, Tamio Mase, Satoru Asada
  • Patent number: 5219744
    Abstract: A process for modifying fats and oils which comprises applying partial glyceride lipase to fats and oils containing partial glycerides and fatty acids to synthesize triglycerides from the partial glycerides by esterification.The lipase is preferably an immobilized lipase and this process is preferably carried out under a water concentration of 1500 ppm or less.By using partial glyceride lipase according to the present invention, there can be obtained modified fats and oils having a low content of diglycerides without changing triglyceride composition.
    Type: Grant

    Date of Patent: June 15, 1993
    Assignees: Ajinomoto Co., Inc., Amano Pharmaceutical Co., Ltd.
    Inventors: Jun Kurashige, Narihide Matsuzaki, Tamio Mase, Shotaro Yamaguchi
  • Patent number: 5061498
    Abstract: The present invention relates to a method for reforming fats and oils which comprises treating the fats and oils containing partial glycerides with two or more kinds of lipases which are different in a fatty acid specificity and/or a position specificity in the presence of a small amount of water to obtain fats and oils containing partial glycerides in a low content in a high yield. According to the invention, a reaction rate and a yield are improved.
    Type: Grant
    Filed: June 14, 1989
    Date of Patent: October 29, 1991
    Assignee: The Japanese Research & Development Association for Bioreactor System in Food Industry
    Inventors: Narihide Matsuzaki, Jun Kurashige, Tamio Mase, Shotaro Yamaguchi
  • Patent number: 3983002
    Abstract: Aeromonas sp. No. 212 is cultured to allow it to produce a novel cellulase 212 and/or novel hemicellulase in a culture medium, and the so produced cellulase 212 and/or hemicellulase 333 is separated from the culture medium.The so separated novel cellulase 212 and/or novel hemicellulase 333 is used as a cellulosic material-decomposing agent in purifying tanks, plants for treatment of industrial waste waters, excrement treatment plants, drainage disposal treatment plants and the like.
