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

    Author : Ola Johnsson; Institutionen för reglerteknik; []
    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

  5. 3. Tools and applications to assess yeast physiology and robustness in bioprocesses: Lab-scale methods from single cells to populations

    Author : Luca Torello Pianale; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Scale-up; fluorescence; scale-down; Saccharomyces cerevisiae; biosensors; microfluidics; bioproduction;

    Abstract : Bioprocesses enable the efficient production of valuable chemicals by microorganisms such as the yeast Saccharomyces cerevisiae . Predictable and stochastic perturbations affect microbial performance in an industrial-scale bioreactor. READ MORE

  6. 4. Robustness quantification in yeast: A methodology to study phenotypic, evolutionary, and genomic aspects of microbial robustness

    Author : Cecilia Trivellin; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; bioproduction; Saccharomyces cerevisiae; adaptive laboratory evolution; High-throughput; fluctuating conditions; perturbations;

    Abstract : Bioprocesses contribute to the shift towards a more sustainable economy. In bioprocesses, valuable chemicals can be generated from renewable resources while, at the same time, reducing carbon emissions. A major hurdle in bringing bio-based products to market is the time and cost involved in designing efficient cell factories. READ MORE

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

    Author : Tarek Dishisha; Bioteknik; []
    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
