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

    Författare :Leonie Wenning; Chalmers tekniska högskola; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 2. Food web structures and carbon transfer efficiencies in a brackish water ecosystem

    Författare :Kristin Dahlgren; Ulf Båmstedt; Agneta Andersson; Marja Koski; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Carbon transfer efficiency; Food web efficiency; zooplankton; production; pelagic; benthic; fatty acids; wax esters; Marine ecology; Marin ekologi;

    Sammanfattning : Two differently structured food webs can be distinguished in the pelagic habitat of aquatic systems; the classical one (autotrophic) with phytoplankton as a base and the microbial food web (heterotrophic) with bacteria as a base. Energy (produced at the basal trophic level) reaches higher trophic levels, i.e. LÄS MER

  4. 3. Improving Productivity and Enzyme Stability Through Process Design: Lipase-catalysed Synthesis of Epoxides and Esters

    Författare :Anna Hagström; Bioteknik; []

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

    Författare :Juan Octavio Valle Rodriguez; Chalmers tekniska högskola; []
    Nyckelord :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;

    Sammanfattning : 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.

  7. 5. Metabolic engineering for production of complex lipids in tobacco (Nicotiana benthamiana) leaves and rice (Oryza sativa) endosperm

    Författare :Selcuk Aslan; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : World chemical and energy supplies for industry are today highly dependent on unsustainable fossil reserves. Vegetable lipids with similar chemical structures to fossil oil could be the ultimate renewable solution to replace fossil oil and provide environmentally friendly feedstocks and energy resources.
