Culturing cells in order to produce substances, comprises setting a glucose limitation in the culture solution. Culturing cells in order to produce substances comprises setting a glucose limitation in the culture solution. The extent of glucose limitation (DGL) equals qGlc/Glc max, where qGlc is the current observed specific glucose consumption rate, and qGlc max is the maximum known glucose consumption rate for the cells in question. DGL lies between 0-1, where 0 is a complete limitation, and 1 represents no limitation (i.e. a complete glucose surplus). According to the invention the DGL is greater than or equal to the DGL that leads to the exclusive preservation of the cell and is 0.5. |
