  2. 21. Physiological Engineering of Xylose Utilisation by Recombinant Saccharomyces cerevisiae

    Author : Nina Quednau Meinander; Teknisk mikrobiologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; protein burden; physiology; fed-batch fermentation; chemostat; recombinant Saccharomyces cerevisiae; ethanol; xylose; xylitol; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    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

  4. 22. Synthesis of jojoba-like wax esters in metabolically engineered strains of Saccharomyces cerevisiae

    Author : Leonie Wenning; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Saccharomyces cerevisiae; very long-chain monounsaturated fatty alcohols; very long-chain monounsaturated fatty acids; jojoba-like wax esters;

    Abstract : Yeast has a long-standing tradition in human history as a production organism of choice. Besides being used for the production of fermented products like bread or beer, it has also been extensively explored for the production of proteins and chemicals. READ MORE

  5. 23. Improving the Response of Saccharomyces cerevisiae to Lignocellulosic Hydrolysate Inhibitors in Ethanolic Fermentation

    Author : Joao Almeida; Teknisk mikrobiologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; furfural; ethanol; fermentation; phenolics; furaldehyde; HMF; ADH1; xylose reductase; tolerance; Saccharomyces cerevisiae; Lignocellulosic hydrolysate inhibitors; ADH6;

    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.

  6. 24. Used but not Sensed - The Paradox of D-xylose Metabolism in Saccharomyces cerevisiae

    Author : Karen Ofuji Osiro; Teknisk mikrobiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; saccharomyces cerevisiae; sugar sensing signalling; D-Xylose; XR XDH; GFP biosensor; cAMP PKA; Snf3p Rgt2p; SNF1 Mig1p; flow cytometry;

    Abstract : The realization that the extraction and combustion of fossil fuels is having serious effects on the environment and the climate, together with the ever-growing need for fuels, has led to the development of the concept of the biorefinery. Biorefineries are refineries in which fossil resources, such as oil, are replaced by renewable biomaterials to produce biofuels and biochemicals. READ MORE

  7. 25. Metabolic engineering of Saccharomyces cerevisiae for polyhydroxybutyrate production

    Author : Kanokarn Kocharin; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; S. cerevisiae; Acetyl-CoA; NADPH; Metabolic engineering; Polyhydroxybutyrate;

    Abstract : Establishing industrial biotechnology for the production of chemical compounds from the biosynthetic pathway has received a significant boost with the implementation of metabolic engineering. At present, metabolic engineering in Saccharomyces cerevisiae gains significant advantages of integration of knowledge acquired through a long history of use and data acquisition from novel –omics technologies hence enabling the development of a tailor-made S.
