  1. 1. Strain- and bioprocess-design strategies to increase production of (R)-3-hydroxybutyrate by Escherichia coli

    Författare :Mónica Guevara-Martínez; Gen Larsson; Antonius J. A. van Maris; Pau Ferrer; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; E. coli; R -3-hydroxybutyrate; metabolic engineering; bioprocess design; NADPH; acetic acid; thioesterase; BAC; Bioteknologi; Biotechnology;

    Sammanfattning : Microbial bio-based processes have emerged as an alternative to replace fossil-based processes for the production of fuels and chemicals. (R)-3-hydroxybutyrate (3HB) is a medium-value chemical that has gained special attention as a precursor of antibiotics and vitamins, as a monomer for the synthesis of tailor-made polyesters and as a nutritional source for eukaryotic cells.

  3. 2. Engineering and applications of surface displayed tyrosinase on Escherichia coli

    Författare :David Hörnström; Antonius J. A. van Maris; Joachim José; KTH; []
    Nyckelord :Bioteknologi; Biotechnology;

    Sammanfattning : The rise of biotechnology has provided a toolbox to deal with major challenges related to pollution and health. Microbial enzymes constitute powerful macromolecules with applications in environmental technology, and industrial and medical production. LÄS MER

  4. 3. Metabolic engineering and cultivation strategies for recombinant production of (R)-3-hydroxybutyrate

    Författare :Mariel Perez-Zabaleta; Gen Larsson; Antonius J. A. van Maris; Diethard Mattanovich; KTH; []
    Nyckelord :Escherichia coli; R -3-hydroxybutyrate; nitrogen limitation; nitrogen depletion; lignocellulose; fed batch; acetate; β-ketothiolase; acetoacetyl-CoA reductase; Halomonas boliviensis.; Bioteknologi; Biotechnology;

    Sammanfattning : Metabolic engineering and process engineering are two powerful disciplines to design and improve microbial processes for sustainable production of an extensive number of compounds ranging from chemicals to pharmaceuticals. The aim of this thesis was to synergistically combine these two disciplines to improve the production of a model chemical called (R)-3-hydroxybutyrate (3HB), which is a medium-value product with a stereocenter and two functional groups.

  5. 4. Engineering short-chain carboxylic-acid metabolism in the model microorganism Escherichia coli

    Författare :Gustav Sjöberg; Antonius J. A. van Maris; Solange Mussatto; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; metabolic engineering; R -3-hydroxybutyrate; volatile fatty acids; bioprocess design; Escherichia coli; bacterial artificial chromosome; Bioteknologi; Biotechnology;

    Sammanfattning : The ever-increasing concern about carbon dioxide emissions has created an urgent need to develop alternative methods to cheaply and renewably produce materials, chemicals and fuels. The biorefinery is uniquely suited to deliver these products from sustainable biomass. LÄS MER

  7. 5. Pharmaceuticals – improved removal from municipal wastewater and their occurrence in the Baltic Sea

    Författare :Berndt Björlenius; Gen Larsson; Antonius J. A. van Maris; Hallvard Ødegaard; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Advanced wastewater treatment; WWTP; pilot plant; pharmaceutical residues; removal of pharmaceuticals; activated carbon; ozonation; nanofiltration; biomarker; Baltic Sea; Bioteknologi; Biotechnology;

    Sammanfattning : Pharmaceutical residues are found in the environment due to extensive use in human and veterinary medicine. The active pharmaceutical ingredients (APIs) have a potential impact in non-target organisms. Municipal wastewater treatment plants (WWTPs) are not designed to remove APIs. LÄS MER
