  • Method of producing a compound by fermentation
    Patent number: 7459294
    Abstract: During the production of a product compound by fermentation, the concentration of a precursor compound is maintained within a pre-selected concentration range by having an adsorbent resin in contact with the culture medium. The adsorbent resin reversibly adsorbs precursor compound and, as un-adsorbed precursor compound is converted to product compound, adsorbed precursor compound is released from the resin, thus maintaining the concentration of precursor compound within the pre-selected range.
    Type: Grant
    Filed: August 6, 2004
    Date of Patent: December 2, 2008
    Assignee: Kosan Biosciences Incorporated

  • Method for production of polyketides
    Patent number: 7067290
    Abstract: A method for the production of a polyketide by fermentation comprising the steps of growing a culture of a polyketide-producing organism at a pH value conducive to cell growth for a time sufficient to generate the producing culture, lowering the pH of the culture to a value conducive to polyketide product stability, continuing the fermentation until a maximal titer of polyketide is achieved, and optionally extracting the polyketide from the culture.
    Type: Grant
    Filed: November 12, 2003
    Date of Patent: June 27, 2006
    Assignee: Kosan Biosciences Incorporated
    Inventors: Rika Regentin, Ruchir P. Desai
