  • Patent number: 5229290
    Abstract: A method is provided for the regeneration of an individual coconut plantlet. It comprises culturing a tissue explant of an undifferentiated male flower of a coconut tree in a culture medium, which contains 10-50 ppm of an auxin, 0.1-3% of a polysaccharide produced by a bacterium of Pseudomonas and 0.05-1% of activated carbon, in a dark place until a shoot-like structure appears; and then culturing under exposure to light of 3,000-20,000 luxes while repeating its subculture in a fresh culture medium.

  • Patent number: 5166196
    Abstract: A composition for curing autoimmune diseases is disclosed. The composition comprises as an effective component an acidic heteropolysaccharide which is secreted by a callus induced from a plant belonging to the genus Polianthes L. The acidic heteropolysaccharide can be prepared as a uniform product by the application of plant tissue culture methods and exhibits superior capability of removing immunocomplexes with the least side effects.

  • Patent number: 5032311
    Abstract: A novel acidic heteropolysaccharide which comprises as its structural units arabinose, mannose, galactose, glucuronic acid, and xylose, at a specific ratio. The polysaccharide can be prepared by culturing a callus induced from a plant belonging to the genus Polianthes L. in a culture medium containing plant hormones. The polysaccharide can be used as a component of agents for external application and detergents, and provides good moisturizing effects and a smooth, satisfying feeling upon use. When formulated in detergents, they produce remarkable improvement in a clean, rich feeling upon use.

  • Patent number: 4962030
    Abstract: Alkaline cellulases having an optimum pH in an alkaline range and being stable over a broad pH range are produced by microorganisms which belong to the genus Bacillus and grow in a neutral medium.These alkaline cellulases are rarely inhibited by ingredients ordinarily incorporated in detergents such as surface active agents, proteinases and chelating agents, so that they can be conveniently used in detergent compositions.

  • Patent number: 4945053
    Abstract: Novel alkaline cellulase K, CMCase I and CMCase II are obtained by isolation from a culture product of Bacillus sp KSM-635.These enzymes stably work in a wide range including an alkaline side, and their activity is shown even at low temperatures. Further, they have a strong resistance to surface active agents, chelating agents and proteinases. Therefore, they can be effectively utilized not only as an additive for clothing detergents, but also as a biomass and in other fields.

  • Patent number: 4943532
    Abstract: Novel alkali-resistant cellulases which have an optimum pH at a neutral region and have a high relative activity in an alkaline region are produced by microorganisms belonging to the genus Bacillus and growing in neutral medium.The cellulases suffer little inhibition by means of detergent ingredients such as surface active agents, proteinases and chelating agents. Therefore, they can be conveniently used as one of ingredients for detergent compositions.
