Temperature limited fed-batch cultivation with a probing feeding strategy for Escherichia coli

In English A cultivation strategy combining the advantages of temperature limitedfed-batch and probing control is presented.This is a suitable way to produce recombinant proteins while minimizing therelease of endotoxins which complicates the downstream processing.The downside with the temperature limited fed-batch technique has been the difficulty to achieve a controlled excess of glucose inthe reactor without the accumulation of acetic acid when usingstandard sensors.A method using a probing feeding strategy withdown-pulses is here suggested. The technique is investigated insimulations and experiments.
