1. 21. Evaluating Sugar Signaling during Xylose Oxidation in Saccharomyces cerevisiae

   University essay from Lunds universitet/Teknisk mikrobiologi

   Author : Viktor Persson; [2020]
   Keywords : Saccharomyces cerevisiae; yeast; xylose oxidation; sugar signaling; biosensor; applied microbiology; teknisk mikrobiologi; Technology and Engineering;

   Abstract : The sugar signaling state of cells oxidizing xylose was investigated through the chromosomal integration of the Weimberg pathway into previously established biosensor strains capable of monitoring the Snf3p/Rgt2p, SNF1/Mig1p, and cAMP/PKA pathways through the expression of HXT1, SUC2, and TPS1, respectively. Ultimately, two new strains were successfully developed containing both the Weimberg pathway and a biosensor for either HXT1 (TMB CB 112) or TPS1 (TMB CB 117). READ MORE

3. 22. Downscaling and modelling of an ion-exchange chromatography column for purifying glucose solutions

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Viktor Geraldsson; [2020]
   Keywords : Ion-exchange; chromatography; glucose; purification; modelling; equilibrium isotherm; Matlab; chemical engineering; kemiteknik; Technology and Engineering; Chemistry;

   Abstract : To utilize sugars as a feedstock for renewable industries, the feedstock often needs to be very pure. This is due to ionic species contaminating the sugar feedstock being potent catalyst poisons in many cases. To remove ionic species from the sugar feedstock, it is dissolved and purified using packed ion-exchange columns. READ MORE

4. 23. Energy & redox fluxes in Lactobacillus reuteri DSM 17938 on different sugars

   University essay from Lunds universitet/Teknisk mikrobiologi; Lunds universitet/Bioteknik

   Author : Katarzyna Bengtsson; [2019]
   Keywords : Energy; redox fluxes; Lactobacillus reuteri DSM 17938; different sugars; applied microbiology; teknisk mikrobiologi; Biology and Life Sciences; Chemistry; Technology and Engineering;

   Abstract : Under anaerobic condition the specific growth rate of Lactobacillus reuteri DSM 17938 on different sugars, was analyzed using spectrophotometry. Electron acceptor (fructose) supported cells to cope with poor energy recovery by re-oxidising the NADH, thus enabling ATP formation thru acetate production, while fermenting glucose via the phosphoketolase pathway (PKP) and simultaneously operating via Embden-Meyerhof pathway (EMP).

5. 24. Intensification of lignocellulosic bioethanol production process using multi-staged membrane bioreactors

   University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

   Author : Clarisse Uwinez; [2019]
   Keywords : Interconnected continuous hydrolysis and fermentation; lignocellulosic bioethanol; Membrane bioreactors; process intensification; lignin recovery; membrane fouling.;

   Abstract : The exploitation of lignocellulosic materials with the aim of producing high value-added products will potentially counteract concerns related to the depletion of fossil resources or exponential population growth. Bioethanol produced from lignocellulosic agriculture residue exhibits promising alternative to the petroleum-based fossil fuel which reduces net emission of greenhouse gases (GHG). READ MORE

6. 25. Enzymatic Modification of the Interaction Between Lignin and Recycled Cellulose Fibers

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Manfred Klug; [2019]
   Keywords : Lignin; Pulp and Paper; Recycling; Biotechnology; Enzyme technology; Laccases; Chemical Engineering; Kemiteknik; Technology and Engineering;

   Abstract : The pulp and paper industry have been a growing market during the last decades. Due to higher environmental concerns among people, the recycling of papers has become an even more important part of the industry. Recycled paper fibers however are of lower quality than virgin fibers. READ MORE
