  1. 1. Dicarboxylic acids from xylose, using natural and engineered hosts

    Författare :Henrik Almqvist; Institutionen för kemiteknik; []
    Nyckelord :Xylose; Dicarboxylic Acids; Biorefineries; Actinobacillus succinogenes; Basfia succiniciproducens; Saccharomyces cerevisiae; Caulobacter crescentus;

    Sammanfattning : Chemical building blocks for plastics can be produced from renewable biomass feedstocks using microbial production organisms, such as yeast or bacteria, in a biorefinery. One class of chemical building blocks that are suitable for production of biobased and biodegradable plastics are dicarboxylic acids, e.g. succinic acid. LÄS MER

  4. 3. Organic acids in root exudates and soil solutions. Importance to calcicole and calcifuge behaviour of plants

    Författare :Lena Ström; Institutionen för naturgeografi och ekosystemvetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; nutrient-solubilisation; iron; phosphate; nutrient-limitations; citrate; oxalate; organic acids; root exudation; acidifuge; Calcicole; calcifuge; adaptations.; Plant ecology; Växtekologi;

    Sammanfattning : Many vascular plant species are unable to colonise calcareous sites, the floristic composition of adjacent limestone and acid silicate soils differing markedly. The inability of these 'calcifuge' species to establish themselves and grow on limestone soil appears to mainly be related to their low capacity for solubilising and absorbing phosphate and/or iron from such soils.

  5. 4. Malic acid production by Aspergillus oryzae

    Författare :Christoph Knuf; Chalmers University of Technology; []
    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

  7. 5. Amino acid conjugation of fatty acids as a novel pathway in lipid metabolism

    Författare :Sarah-Jayne Reilly; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Peroxisomes are cell organelles that play an important role in the metabolism of a variety of lipids including very long chain fatty acids, dicarboxylic acids, bile acids, and xenobiotic carboxylic acids to name a few. To accomplish these tasks peroxisomes contain many proteins involved in lipid metabolism including members of the Type I acyl-CoA thioesterase/acyltransferase protein family. LÄS MER
