  • Patent number: 7473540
    Abstract: A method of producing an organic acid by staining a yeast population with a stain capable of internal pH (pHi)-dependent fluorescence, to yield a stained yeast population; determining a gate pH and a corresponding fluorescence parameter of the stained yeast population; and sorting the cells of the stained yeast population such that the cells having a pHi above the gate pH are retained and the cells having a pHi below the gate pH are discarded, to yield a yeast population for the production of the organic acid. Also, a method of producing an organic acid by performing the above steps, followed by isolating individual cells of the yeast population, to yield individual yeast cells for the production of an organic acid; culturing an individual yeast cell, to yield a cloned yeast population for the production of an organic acid; and incubating the cloned yeast population for the production of an organic acid in a medium containing an organic acid precursor, to produce the organic acid.

  • Publication number: 20070065905
    Abstract: Herein is disclosed a method for the production of proteins. The protein is expressed by a yeast belonging to the species Zygosaccharomyces bailii. The yeast secretes the protein produced into the culture medium from where it is isolated, thereby simplifying the isolation process. Preferably the yeast is cultivated in chemically defined medium, thereby further simplifying the isolation process significantly.
