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

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

    Abstract : 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. READ MORE

    Abstract : 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. READ MORE

  3. 3. Analysis and Control of Continuous Microaerobic Ethanol Production by Yeast

    Author : Carl Johan Franzén; Chalmers University of Technology; []
    Keywords : nitrogen limitation; ethanol; Saccharomyces cerevisiae; glycerol; metabolic flux analysis; oxygen limitation; stoichiometric model; yeast physiology; RQ control;

    Abstract : 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. READ MORE
