  • Microbial process for producing hydrogen
    Patent number: 6395521
    Abstract: In hydrogen production with microorganisms, cultivation of a microalga under light and aerobic conditions and/or hydrogen production by a photosynthetic bacterium under light and anaerobic conditions are performed with a transparent tower-type air-lift culture tank. Hydrogen can be produced more efficiently with a dual cylindrical structure and a helical flow promoter.
    Type: Grant

    Date of Patent: May 28, 2002
    Inventor: Yoshiharu Miura
  • Reformer seal plate arrangement
    Patent number: 4921680
    Abstract: A stepped support and seal plate (44) is sealed to firing tube (18) with an axially compressed seal (62). It carries sleeves (24) and is sealed thereto by gasket seals (55). A diagonal movement seal (69) seals plate (44) to the wall of pressure vessel (10). Bellows (76) has a straight portion (77) at the hot end. Insulation (14) is tapered to provide variations in heat transfer from the bellows to provide a uniform strain pattern in the bellows.

  • Use of an organ culture of Catharanthus roseus to produce vincristine and vinblastine
    Patent number: 4910138
    Abstract: A method of preparing an organ culture from branched tissue of a Catharanthus roseus seedling is disclosed. The indole alkaloids vincristine and vinblastine can be recovered from the organ culture tissue via extraction.

    Date of Patent: March 20, 1990
    Assignee: Yoshiharu Miura
    Inventors: Yoshiharu Miura, Kazumasa Hirata
  • Process for producing hydrogen by alga in alternating light/dark cycle and environmental aerobic/microaerobic conditions
    Patent number: 4532210
    Abstract: Hydrogen is biologically, effectively produced by an alga in an alternating light/dark cycle which comprises alternating a step for cultivating the alga in water under aerobic conditions in the presence of light to accumulate photosynthetic products in the alga and a step for cultivating the alga in water under microaerobic conditions in the dark to decompose accumulated material by photosynthesis to evolve hydrogen.

  • Production of microbial cells from methanol
    Patent number: 4368271
    Abstract: Microbial cells are produced in great quantities and good yield, and economically by cultivating a bacterium belonging to species selected from the group consisting of Flavobacterium tosaensis, Pseudomonas wakayamaensis, Flavobacterium methanolicola, Corynebacterium yamanasiensis, in a culture medium containing methanol as a major carbon source. Methanol is abundantly available from the chemical industry. The resultant microbial cells have a high protein content and can be utilized as feed, food, medical and industrial materials.
