  1. 1. Malic acid production by Aspergillus oryzae

    Författare :Christoph Knuf; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; C4 dicarboxylic acids; Aspergillus oryzae; systems biology; fermentation; malic acid; metabolic engineering;

    Sammanfattning : Malic acid is a C4 dicarboxylic acid which is used as an acidulant in food and beverages. It isalso considered as a bio-building block to replace petrochemically derived compounds in thepost oil era. This organic acid can be biotechnologically derived from fermentation usingrenewable feedstocks as carbon source. LÄS MER

  3. 2. Wild plants can improve their rhizosphere chemistry in acid soils

    Författare :Marion Schöttelndreier; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Växtekologi; Plant ecology; wild plants.; time pattern; soil heterogeneity; rhizotrons; rhizosphere; pH; oxalic acid; nutrient availability; malic acid; hydroponics; citric acid; 14C; biodegradation; acid soils; aluminium toxicity; Soil Science; agricultural hydrology; Lantbrukshydrologi; marklära; Plant biochemistry; Växtbiokemi;

    Sammanfattning : Growth conditions on acid soils may be hampered by low nutrient availability and phytotoxic Al (aluminium) concentrations. In this thesis I present my studies on adaptation mechanisms of wild plants to acid soils in the close root environment, the rhizosphere. LÄS MER

  5. 4. Pyridine Nucleotides in Plant Mitochondria. Amounts, metabolism and contribution to electron transport

    Författare :Stephanie C Agius; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Växtbiokemi; Plant biochemistry; antibody; Botanik; NAD-pyrophosphatase; Botany; NADH:ubiquinone oxidoreductase; NADPH dehydrogenase; plant mitochondria; pyridine nucleotides;

    Sammanfattning : HPLC analysis was used for direct quantification of amounts and redox levels of pyridine nucleotides in plant mitochondria. The amount of NAD(H) and NADP+ varied, 1.0-3.7 and 0-0. LÄS MER

  7. 5. Design, Synthesis, and Structure-Activity Relationships Analysis of Potential Inhibitors of the Serine Protease Thrombin and the Malarial Aspartic Proteases Plasmepsin I and II

    Författare :Anders Dahlgren; Thomas Olsson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The design, synthesis, and structure-activity relationships analysis of some potential protease inhibitors are outlined in this thesis. In particular, the serine protease thrombin and the malarial aspartic proteases plasmepsin I and II (Plm I and II) are described in regard to the roles they play in living organisms, and that is followed by discussions concerning the design, synthesis, and biological test results of inhibitors of these enzymes.
