2. 1. Pharmaceuticals – improved removal from municipal wastewater and their occurrence in the Baltic Sea

   Author : Berndt Björlenius; Gen Larsson; Antonius J. A. van Maris; Hallvard Ødegaard; KTH; []
   Keywords : 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;

   Abstract : 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. READ MORE

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

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

   Abstract : 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.

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

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

   Abstract : 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. READ MORE

6. 4. Analysis and engineering of central metabolism in Clostridium thermocellum

   Author : Teun Kuil; Antonius J. A. van Maris; Ruud Weusthuis; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Clostridium thermocellum; biofuels; ethanol; atypical glycolysis; pyrophosphate; phosphofructokinase; thermodynamic driving force; redox cofactor balancing; amino acid secretion; chaotropicity; hexose utilization; laboratory evolution; metabolic engineering; Biotechnology; Bioteknologi;

   Abstract : To mitigate climate change, greenhouse gas emissions must be reduced to net-zero in 2050 requiring a drastic transition in today´s energy sector. To achieve this goal, the use of biofuels produced from lignocellulosic feedstocks, including agricultural and forestry residues, is expected to play an important role. READ MORE

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

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

   Abstract : 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.
