  1. 1. Development of soft sensors for monitoring and control of bioprocesses

    Författare :Robert Gustavsson; Carl-Fredrik Mandenius; Johan Hyllner; Carl Johan Franzén; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In the manufacture of bio-therapeutics the importance of a well-known process is key for a high product titer and low batch to batch variations. Soft sensors are based on the concept that online sensor signals can be used as inputs to mathematical models to derive new valuable process information. LÄS MER

  3. 2. Operator Training Simulators towards Industrial Biotechnology

    Författare :Inga Gerlach; Carl-Fredrik Mandenius; Volker C. Hass; Carl Johan Franzén; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Biotechnological processes are carried out by applying advanced and demanding process strategies. Thus, fundamental understanding and knowledge about the applied microorganism is required to achieve high productivity and profitability. LÄS MER

  5. 4. Analysis and Control of Continuous Microaerobic Ethanol Production by Yeast

    Författare :Carl Johan Franzén; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nitrogen limitation; ethanol; Saccharomyces cerevisiae; glycerol; metabolic flux analysis; oxygen limitation; stoichiometric model; yeast physiology; RQ control;

    Sammanfattning : Glucose fermentation by Saccharomyces cerevisiae, and xylose fermentation by Candida utilis and Pichia stipitis, were investigated under microaerobic conditions. A dynamic experimental method named oxygen programmed fermentation (OPF), and a method for microaerobic RQ control in continuous culture have been developed. LÄS MER
