  • Production of beta-1,3-glucan in Euglena
    Patent number: 5084386
    Abstract: Substantially pure, pyrogen-free beta-1,3-glucan is produced by cultivating Euglena cells in a defined growth medium and under specified conditions that provide a cell mass comprising 70% to 90% beta-1,3-glucan on a dry weight basis, separating the cell mass from the super-natant, extracting the cell mass with methanol and chloroform, acid-washing the extracted cell mass, and washing the acid-treated material with water.
    Type: Grant
    Filed: March 31, 1989
    Date of Patent: January 28, 1992
    Assignee: SRI International
    Inventors: Daniel Tuse, Leticia Marquez, Leslie A. Hokama
  • Flavor composition and method
    Patent number: 5057424
    Abstract: A vanilla flavor composition is produced by vanilla-plant callus cells suspended in tissue culture, under conditions which promote secretion of vanilla flavor components into the culture medium. The flavor components may be separated from the medium by adsorption resins. Also disclosed are methods for preparing callus cells capable of secreting flavor components in tissue culture, and callus cells produced thereby.

    Inventors: Mark E. Knuth, Om P. Sahai
  • Microtuber propagation of potatoes
    Patent number: 5047343
    Abstract: The production of potatoes by growing a large number of independent shoot axes, each of which will form one or more microtubers, from a single microtuber is disclosed. This system has three interconnected stages: (1) the formation of a microtuber shoot complex by inducing shoot tip necrosis in the apical shoot; (2) the elongation of the resulting multiple shoot axes, and (3) the tuberization of the multiple shoot axes.
