  • Publication number: 20240240133
    Abstract: The invention relates to an industrial bioreactor with a dual cycle-controlled optimization process providing an optimized cultivation process for cell cultures, cell components or metabolic products of the cells in a nutrient medium. The bioreactor comprises a reactor vessel providing controlled bioreactor conditions for the cultivation process, a control unit connected to sensory devices measuring sensory parameter values comprising at least measures related to the composition of the nutrient medium and/or concentration of the nutrient medium and/or oxygen and/or temperature and/or pH-value and/or sterility, and transmitting them to the control unit. The control unit controls and automatically optimizes the operational parameter of the cultivation process and operational parameters of a treatment process applied to the cells during the cultivation process by adjusting operational parameters of the bioreactor affecting the measured sensory parameter values.
