  • Fermentation post-sterile additive delivery method and apparatus
    Publication number: 20020039781
    Abstract: A fermentation process post-sterile additive device and method of operation is detailed. The device is used to deliver additive as a heavy-drop mist. The mist covers the entire fermenting batch head surface of the vat broth. This improves mixing and reduces the amount of additive to appropriate introduction levels throughout log phase fermentation, preventing coating of cultivating cells and interference with cell respiration. A steady state growth rate is fostered.
    Type: Application
