  4. 17. The temperature-limited fed-batch technique for control of Escherichia coli cultures

    Author : Marie Svensson; Sven-Olof Enfors; John Villadsen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Endotoxin; Escherichia coli; fed-batch technique; glucose-limitation; mathematical model; Bioengineering; Bioteknik;

    Abstract : The objective of this study was to investigate the physiology and productivity in Escherichia colicultures with emphasis on the temperature-limited fed-batch (TLFB) culture. The TLFB techniquecontrols the oxygen consumption rate of the growing culture by a gradually declining temperaturefrom 37-35 °C down to 20-18 °C. READ MORE
