2. 21. Innovative Bioreactors for the Degradation of Polycyclic Aromatic Hydrocarbons

   Author : Benoit Guieysse; Bioteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; Bioteknik; Biotechnology; PAH; degradation; aromatic; contaminant; pollutant; bioreactor; organic pollutant; kontroll av utsläpp; Miljöteknik; pollution control;

   Abstract : The development of biological reactors for the treatment of toxic and recalcitrant organic pollutants is a complex task. Firstly, microbial inoculation, acclimation and selection must be optimized to provide the best microflora possible. READ MORE

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

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

   Abstract : 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. READ MORE

5. 23. 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.

6. 24. Anaerobic digestion of crop residues at low temperatures

   Author : Irene Bohn; Bioteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioteknik; Biotechnology; kontroll av utsläpp; Miljöteknik; Environmental technology; pollution control; methanogens; low temperature; crop residues; Anaerobic digestion; farm-scale digestion; fluorescence in situ hybridization;

   Abstract : Biogas is a renewable source of energy. Residues from agriculture contain considerable energy potential and are suitable substrates for biogas production, but in Sweden the utilization of these residues is low. The economic feasibility of biogas production in general is low, and only limited subsidies are provided by the state. READ MORE

7. 25. Synthetic biology approaches for improving production of fatty acid-derived compounds in cyanobacteria

   Author : Ivana Cengic; Elton P. Hudson; Mathias Uhlén; Annegret Wilde; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cyanobacteria; metabolic engineering; surface display; CRISPRi; fatty alcohols; fatty acid synthesis; aldehyde deformylating oxygenase; Bioteknologi; Biotechnology;

   Abstract : The environmental consequences associated with the use of fossil-sourced fuels and chemicals have brought with it a realization that future development must move in a more sustainable direction. Currently available biofuels or renewably produced chemical, such as bioethanol or biodiesel, are produced from microbial fermentation of sugar-rich crops or by chemical conversion of natural oils or fats.
