摘要 |
This invention relates to methods for monitoring and controlling bioprocesses. Specifically, it describes using quasi-real-time analytical and numerical techniques to analyze optical loss measurements calibrated to indicate cell viability, whereby it is possible to reveal process changes and/or process events such as feeding or induction. Additionally, the present invention makes it possible to accurately estimate the onset of a decrease in cell viability and/or a suitable time for cell harvesting for a cell culture growth process. Pattern recognition methods for identifying specific process events such as batch feeding, cell infection, and product precipitation are also described.
