21. Metabolic Engineering of the Pentose Phosphate Pathway of Xylose Fermenting Saccharomyces cerevisiae
Abstract : The aim of the work presented in this thesis is the improvement of xylose fermentation performance of recombinant Saccharomyces cerevisiae strains expressing XYL1 and XYL2 from Pichia stipitis, encoding xylose reductase (XR) and xylitol dehydrogenase (XDH). A recombinant strain of S. READ MORE

22. Multidimensional engineering for the production of fatty acid derivatives in Saccharomyces cerevisiae
Abstract : 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.

23. Physiological Engineering of Xylose Utilisation by Recombinant Saccharomyces cerevisiae
Abstract : Xylitol production by recombinant, XYL1-expressing Saccharomyces cerevisiae was investigated in fed-batch fermentation using different cosubstrates for growth, and generation of reduced cofactors and maintenance energy. Xylose was converted into xylitol with 1:1 yield. READ MORE

24. Improving the Response of Saccharomyces cerevisiae to Lignocellulosic Hydrolysate Inhibitors in Ethanolic Fermentation
Abstract : The production of ethanol based on lignocellulosic biomass requires the fermentation of a hydrolysate containing hexose and pentose sugars in an inhibitory environment. In fact, the lignocellulosic hydrolysate obtained from pretreatment and hydrolysis of the raw material contains a variety of inhibitory compounds, including (i) the furaldehydes 5-hydroxymethyl-2-furaldehyde (HMF) and 2-furaldehyde (furfural), (ii) weak acids (e.

25. Phytases in Saccharomyces cerevisiae. Exploring genes and proteins for the improvement of strains
Abstract : 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. READ MORE
