  2. 16. Enthalpy and Entropy in Enzyme Catalysis : A Study of Lipase Enantioselectivity

    Author : Jenny Ottosson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biocatalysis; enzyme catalysis; Candida antarctica lipase B; enantioselectivity; enthalpy; entropy; CALB; enantiomeric ratio; Bioengineering; Bioteknik;

    Abstract : Biocatalysis has become a popular technique in organic synthesis due to high activity and selectivity of enzyme catalyzed reactions. Enantioselectivity is a particularly attractive enzyme property, which is utilized for the production of enantiopure substances. READ MORE

  4. 17. Microbial Synthetic Biology, Systems Metabolic Engineering and Enzyme Engineering for Advanced Microbial Biodiesel Production with Saccharomyces cerevisiae

    Author : Juan Octavio Valle Rodriguez; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; protein rational engineering; wax ester synthase; hydrolase; advanced biofuel; fatty acid metabolism; directed evolution; chromosomal delta-integration;

    Abstract : The continuous requirement of transportation biofuels has brought the necessity to establish alternatives permitting low-cost production of biodiesel while being environmentally friendly. Biodiesel production was achieved utilizing Saccharomyces cerevisiae by employing respective enzymes that catalyze the synthesis of fatty acid ethyl esters (FAEEs) based on fatty acyl-CoA molecules and ethanol.

  5. 18. Thermal tolerance in teleost fish –importance of cardiac oxygen supply, ATP production and autonomic control

    Author : Andreas Ekström; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; acclimation; coronary; CTmax; enzyme; global warming; heart; mitochondria;

    Abstract : Temperature tolerance is a key determinant of the resilience and adaptability of fish facing a warmer and more thermally variable future with climate change. Yet, the underlying physiological mechanisms determining the critical thermal maximum (CTmax) are poorly understood. READ MORE

  6. 19. Engineering Lipid Metabolism for Production of Oleochemicals in Saccharomyces cerevisiae

    Author : Paulo Teixeira; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oleochemicals; lipid homeostasis; Saccharomyces cerevisiae< i>; lipid metabolism;

    Abstract : Oleochemicals are chemicals usually derived from plant oils or animal fat. Large use of plant oil derivatives as replacements for petroleum-derived chemicals brings sustainability issues from extensive cultivation of oil plants in restricted regions. READ MORE

  7. 20. Biobased Adipic Acid - Challenges in Establishing a Cell Factory

    Author : Emma Skoog; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 2-hexenedioic acid; enzyme engineering; 6-aminohex-2-enoic acid; S. cerevisiae; adipic acid pathway via lysine; cell factory; C. viswanathii; lignocellulose; biorefinery; tolerance; in silico docking; adipic acid;

    Abstract : Growing concern regarding climate change calls for sustainable solutions to significantly reduce our dependency on non-renewable fossil-based raw materials. One potential solution is the development of biorefineries where biobased, renewable raw materials are converted into valuable products via enzymatic, chemical or microbial conversion. READ MORE
