  2. 1. New Roads for an Ancient Enzyme : Whole-Cell Studies and New Cofactors for [FeFe] Hydrogenases

    Author : Marco Lorenzi; Gustav Berggren; Hannah Shafaat; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; [FeFe] hydrogenases; hydrogen; catalysis; photocatalysis; spectroscopy; whole-cell; semi-artificial enzymes; Chemistry with specialization in Molecular Biomimetics; Kemi med inriktning mot molekylär biomimetik;

    Abstract : [FeFe] hydrogenases rare Nature’s best H2-processing catalysts, and one of the best candidates to satisfy societal need for cheap and efficient catalyst for H2-evolution. These enzymes owe their remarkable catalytic activities to their organometallic active site, called “H-cluster”. READ MORE

  4. 2. Farm to furan derivatives : Fractionation of agricultural residues and transformation of sugars to chemical building blocks

    Author : Sara Jonsdottir Glaser; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biorefinery; sugar beet pulp; wheat bran; agricultural residue; biomass valorisation; fractionation; bio-based platform chemicals; HMF; levulinic acid; heterogeneous catalysis; whole-cell catalysis;

    Abstract : The transition of industrial production from petrochemistry to a more sustainable economy requires the use of carbon neutral, renewable feedstock, which does not compete with food and feed supplies – by-products of farming and agro-food industry offer this possibility. With a limited range of low-value applications today coupled with the need for maximal utilisation of resources, the by-products of farming can be repurposed as feedstock for biorefineries.

  5. 3. Microbial Production of Bio-Based Chemicals: A Biorefinery Perspective

    Author : Tarek Dishisha; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biorefinery; platform chemical; organic acid; propionic acid; 3-hydroxypropionic acid; 3-hydroxypropionaldehyde; methacrylic acid; 1; 3-propanediol; Propionibacterium acidipropionici; Lactobacillus reuteri; Gluconobacter oxydans; high cell density fermentation; biotransformation; product inhibition; cell recycle; immobilized cells; chemical catalysis; pdu operon;

    Abstract : A shift from fossil- to renewable biomass feedstock for the emerging bio-based economy requires the development and adoption of new sustainable technologies that are more suited for transformation of biomass components to chemicals, materials and energy. This thesis presents investigations on the development of processes based on industrial biotechnology as a key element for the production of chemicals from agro-/industrial by-products. READ MORE
