  • Oxygen permeable membrane in fermenter for oxygen enrichment of broth
    Patent number: 4649114
    Abstract: The growth of animal cells in a fermenter is promoted by enriching the liquid nutrient medium or broth with oxygen diffused into the liquid through a permeable membrane, such as one made of silicone rubber or polytetrafluoroethylene (Teflon). Superior cell growth in larger volumes is achieved by feeding in the oxygen in this way instead of bubbling it in.
