  1. 1. Perturbation-based Control of Industrial Fed-batch Bioprocesses

    University dissertation from Department of Automatic Control, Lund Institute of Technology, Lund University

    Author : Ola Johnsson; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; perturbation-based control; process control; fed-batch control; industrial bioprocesses;

    Abstract : The topic of this thesis is bioprocess control, more specifically control of industrial-scale microbial fed-batch bioprocesses. Its focus is therefore on methods which are easy to implement in an industrial setting, which gives certain limitations on sensors, actuators and control systems. READ MORE

  3. 3. Microbial Production of Bio-Based Chemicals: A Biorefinery Perspective

    University dissertation from Department of Automatic Control, Lund Institute of Technology, Lund University

    Author : Tarek Dishisha; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biorefinery; platform chemical; organic acid; propionic acid; 3-hydroxypropionic acid; 3-hydroxypropionaldehyde; methacrylic acid; 1; 3-propanediol; Propionibacterium acidipropionici; Lactobacillus reuteri; Gluconobacter oxydans; high cell density fermentation; biotransformation; product inhibition; cell recycle; immobilized cells; chemical catalysis; pdu operon;

    Abstract : A shift from fossil- to renewable biomass feedstock for the emerging bio-based economy requires the development and adoption of new sustainable technologies that are more suited for transformation of biomass components to chemicals, materials and energy. This thesis presents investigations on the development of processes based on industrial biotechnology as a key element for the production of chemicals from agro-/industrial by-products. READ MORE

  4. 4. Growth rate control of periplasmic product retention in Escherichia coli

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Emma Bäcklund; Gen Larsson; Stefan Schmidt; Amelie Eriksson Karlström; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Escherichia coli; fed-batch; outer membrane proteins; recombinant proteins; specific growth rate; periplasmic retention; phosphotransferase system; high cell density cultivation; acetate formation; TECHNOLOGY Bioengineering; TEKNIKVETENSKAP Bioteknik;

    Abstract : The recombinant product is secreted to the periplasm in many processes where E. coli is used as host. One drawback with secretion is the undesired leakage of the periplasmic products to the medium.The aim of this work was to find strategies to influence the periplasmic retention of recombinant products.

  5. 5. Improving selectivity in protein extraction by subtle interactions and environmental changes

    University dissertation from Department of Biotechnology, Lund University

    Author : Sheryl Fernandes; [2001]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Difference Spectroscopy; Circular dichroism; Biotechnology; Bioteknik; Chemical technology and engineering; Kemiteknik och kemisk teknologi; Fluorescence spectroscopy; Metal ions; Cibacron blue; Polyvinylpyrrolidone; Polyethylene glycol; Triton X-114; His 6 tag; Cold-active ß-lactamase; Cold-active ß-galactosidase; Lactate dehydrogenase; Cutinase; Affinity Extraction; Conformational change; Partial Denaturation; Molecular interaction; Aqueous two-phase systems; Detergent foam;

    Abstract : The challenges for efficient bioprocesses lie in developing and adapting further current technologies or in creating innovative separation technologies. The thesis is based on the studies on protein recovery from crude feedstocks by extraction in aqueous two-phase systems and detergent foam, respectively. READ MORE
