  • Humectant, antistatic agent, dispersant and film-forming agent having polysaccharide as active principle, preparation process of polysaccharides, and Kliebsiella ocytoca TNM-3 strain
    Patent number: 5989874
    Abstract: The disclosure describes a humectant, antistatic agent, film-forming agent or dispersant comprising an effective amount of a polysaccharide produced by two strains of Kliebsiella composed of D-glucuronic acid, L-rhamnose, D-galactose and D-glucose in a molar ratio of D-glucuronic acid:L-rhamnose:D-galactose:D-glucose=0.8-1.2:2.4-3.6:0.8-1.2:0.8-1.2.
    Type: Grant
    Filed: March 22, 1996
    Date of Patent: November 23, 1999
    Assignee: Tayca Corporation
    Inventors: Osamu Nakanishi, Yoichi Ooiso, Takeshi Okumiya, Ryosuke Sugihara, Kaoru Kawashima
  • Immunoactivating agent
    Patent number: 5760213
    Abstract: An immunoactivating agent comprising a polysaccharide consisting essentially of glucuronic acid, rhamnose, galactose and glucose in a molar ratio of glucuronic acid:rhannose:galactose:glucose=0 to 1.2:2.4 to 3.6:0.8 to 1.2:0.8 to 2.4. This immunoactivating agent has an excellent immunoactivating activity, and the polysaccharide is a microbially produced acidic heteropolysaccharide having higher productivity than the basidiomycete-derived polysaccharides such as krestin and lentinan.

  • Polysaccharide, process for production thereof, use thereof, and agrobacterium radiobacter TNM2 strain
    Patent number: 5739014
    Abstract: A polysaccharide having a molecular weight of about 5.times.10.sup.3 to 10.times.10.sup.6 as measured by gel permeation chromatography and composed of 5 saccharides, viz. D-glucose, D-galactose, D-glucuronic acid, D-ribose and D-riburonic acid, in a molar ratio of D-glucose:D-galactose:D-glucuronic acid:D-ribose:D-riburonic acid=10:1.8-2.9:1.8-2.6:0.5-1.7:0.5-1.7, with the content of o-acetyl groups in the polysaccharide being 0-10% by weight.

  • Polysaccharides, process for producing polysaccharides, uses of polysaccharides and Azotobacter beijerinckii TNM1
    Patent number: 5527904
    Abstract: Disclosed are novel polysaccharides having the following physicochemical properties: (1) a molecular weight determined by gel filtration chromatography is about 5.times.10.sup.3 to 10.times.10.sup.6, (2) the constituent glycoses are D-galacturonic acid, L-rhamnose and D-glucose, (3) the constituent glycoses are joined substantially by 1,3-linkages, and (4) a configuration of D-galacturonic acid is .alpha., that of L-rhamnose is .beta. and that of D-glucose is .alpha.. A process for producing polysaccharides composed of D-galacturonic acid, L-rhamnose and D-glucose, use of the polysaccharides and a strain for producing the polysaccharides are also disclosed.
