    Abstract : Conversion of biomass to liquid fuels, such as ethanol, has been investigated during the past decades. First due to the oil crisis of the 1970s and lately because of concerns about greenhouse effect, ethanol has been found to be a suitable substitute for gasoline in transportation. READ MORE

  3. 3. A study of ethylene production via the 2-oxoglutarate dependent pathway in S. cerevisiae

    University dissertation from Chalmers University of Technology

    Abstract : The search for alternatives to oil-based monomers has sparked interest for scientists to focus on the use of renewable resources for energy production, for the synthesis of polymeric materials and in other areas. With the use of renewable resources, scientists face new challenges to first isolate interesting molecules and then to process them. READ MORE

  5. 5. Amine Transaminases in Biocatalytic Amine Synthesis

    University dissertation from Stockholm : Henrik Land

    Author : Henrik Land; KTH.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Amine Transaminase; Biocatalysis; Transamination; Reductive Amination; Enzyme; Enzyme Engineering; Equilibrium Displacement; Screening; Enzyme Stability; Biotechnology; Bioteknologi;

    Abstract : The use of enzymes, nature´s own catalysts, both isolated or as whole cells to perform chemical transformations is called biocatalysis. As a complement to classical chemical catalysis, biocatalysis can be an environmentally friendly and more economical option in the production and synthesis of chemicals. READ MORE
