A U.S. Patent Application for “Growth Control of Eukaryotic Cells” was published by Roche on February 27th, 2020. The present invention is a system configured to receive a target cell density and a target time and for each of a plurality of time intervals; receive a measured cell density of the eukaryotic cells in the culture medium of the first tank; compute a predicted cell density at target time as a function of at least the measured cell density; compare the predicted cell density and the target cell density; adjusting the temperature of the culture medium in the first tank if the predicted cell density deviates from the target cell density by increasing the temperature by 0.1.degree… Learn More
