  2. 1. Bacteria and geochemistry in a former uranium open pit mine - mobilization of trace metals

    Author : Frida Edberg; Sara J. M. Holmström; Hans Borg; Stephan M. Kraemer; Stockholms universitet; []
    Keywords : Pseudomonas fluorescens; siderophore; Ranstad; alum shale; iron; pyrosequencing; redox; size fractionation; NATURAL SCIENCES; NATURVETENSKAP; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : In mining areas around the world, chemical and biotic processes have lead to the release of toxic substances, e.g. metals. Microbial processes influence metal speciation, while the chemical environment shapes and controls microbial populations. READ MORE

  4. 2. Microbial mobilisation of Fe and other trace elements in fresh waters: the role of siderophores produced by Pseudomonas fluorescens

    Author : Frida Edberg; Stockholms universitet; []
    Keywords : Environmental science;

    Abstract : .... READ MORE

  5. 3. Towards bacterial valorization of low molecular weight lignin

    Author : Krithika Ravi; Avdelningen för kemiteknik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Pseudomonas putida; Microbacterium sp.; Guaiacol; Syringate; Kraft lignin; Bioconversion; Biorefineries;

    Abstract : Lignin is one of the major constituents in lignocellulosic biomass and is the mostabundant source of renewable aromatics on terrestrial ecosystems. The workcarried out in this thesis concerns bacterial conversion of low molecular weightlignin. READ MORE

  6. 4. Enzymatic synthesis of lipids containing omega-3 fatty acids

    Author : Ann-Marie Lyberg; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; enzymologi; Proteiner; enzymology; Proteins; Enzymes; DHA; EPA; Biotechnology; Bioteknik;

    Abstract : Docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) are omega-3 fatty acids, which have health promoting effects. Since they are highly prone to oxidation, they should be protected, in particular DHA. READ MORE

  7. 5. Hydroxamate Siderophores and Low Molecular Mass Organic Acids in Terrestrial and Aquatic Environments Determined by Liquid Chromatography Mass Spectrometry

    Author : Sofia Essén; Ulla Lundström; Dan Bylund; Mittuniversitetet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chemistry; Kemi;

    Abstract : Siderophores are low molecular mass organic compounds with high iron(III) stability constants. They are produced by many microorganisms, often in combination with low molecular mass organic acids (LMMOAs). Both siderophores and LMMOAs accelerate mineral weathering, thereby enhancing mineral nutrient availability. READ MORE
