  • Patent number: 12252681
    Abstract: Disclosed herein are systems, devices, and methods for sterilization. In some variations, a method of sterilizing a bioreactor system may comprise circulating a sterilant in a bioreactor and an enclosed vessel in fluidic communication with the bioreactor. The enclosed vessel may comprise cell culture media. The sterilant may be circulated for a dwell time sufficient to sterilize at least one of the bioreactor, the vessel, and the cell culture media.

  • Publication number: 20230203446
    Abstract: This disclosure relates to methods of washing cells from a grown cell mass to remove cell culture media and enriching the cells with a finishing media. The disclosed method includes growing a cell mass in cell culture media and then collecting and washing the grown cell mass with a series of wash buffers or a gradient wash buffer that changes over time. While the cell culture media contains nutrients and components beneficial for cell growth, cells grown in cell culture media often have off flavors, off aromas, poor color, poor salt/minerality compositions, and other shortcomings. Accordingly, the disclosed method comprises removing cell culture media remnants from a grown cell mass using a single or a series of wash media. The grown cell mass is further washed with a finishing or enrichment buffer to further improve sensory aspects and nutritional composition of the grown cell mass.
