4. 18. Metabolic engineering and random mutagenesis for improved xylose utilisation of Saccharomyces cerevisiae

   Författare :Fredrik Wahlbom; Teknisk mikrobiologi; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biokemisk teknik; Biochemical technology; mykologi; virologi; bacteriology; Microbiology; Kemiteknik och kemisk teknologi; Chemical technology and engineering; ethanol; Saccharomyces; xylose; virology; mycology; Mikrobiologi; bakteriologi;

   Sammanfattning : In this thesis I have summarised my work on the analysis and improvement of xylose utilisation by recombinant S. cerevisiae. A metabolic flux model was developed and used to analyse the intracellular fluxes in the recombinant xylose utilising S. cerevisiae TMB 3001 cultivated in chemostat at various dilution rates and xylose/glucose concentrations.

5. 19. Multidimensional engineering for the production of fatty acid derivatives in Saccharomyces cerevisiae

   Författare :Yating Hu; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; protein engineering; Saccharomyces cerevisiae; fatty acid derivatives; metabolic engineering; tolerance; transporter;

   Sammanfattning : Saccharomyces cerevisiae , also known as budding yeast, has been important for human society since ancient time due to its use during bread making and beer brewing, but it has also made important contribution to scientific studies as model eukaryote. The ease of genetic modification and the robustness and tolerance towards harsh conditions have established yeast as one of the most popular chassis in industrial-scale production of various compounds.

7. 20. Phytases in Saccharomyces cerevisiae. Exploring genes and proteins for the improvement of strains

   Författare :Jenny Veide; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; phytase; yeast; acid phosphatase; in vitro digestion; PHO; Saccharomyces cerevisiae; phytate; myo-inositol hexaphosphate;

   Sammanfattning : Degradation of myo-inositol hexaphosphate (InsP6, phytate) in food or feed by InsP6-degrading enzymes (phytases) is known to increase the availability of minerals and phosphate, which leads to a higher nutritional value. The aim of this work was to explore the extracellular degradation of InsP6 by Saccharomyces cerevisiae. LÄS MER
