  1. 1. Metabolic Engineering of the Central Carbon Metabolism in Streptococcus thermophilus for Enhanced Exopolysaccharide Production

    Författare :Malin Svensson; Teknisk mikrobiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; Livsmedelsteknik; Biotechnology; Bioteknik; Biokemisk teknik; Biochemical technology; Analytisk kemi; Analytical chemistry; metabolism; Biokemi; Metabolism; mykologi; Biochemistry; virologi; Mikrobiologi; bakteriologi; virology; mycology; bacteriology; Streptococcus thermophilus; Microbiology; Metabolic engineering; Lactic acid bacteria; Exopolysaccharides; Central carbon metabolism;

    Sammanfattning : The lactic acid bacterium, Streptococcus thermophilus, is used in the dairy industry in mixed cultures with Lactobacillus delbrueckii subsp. bulgaricus for the production of yoghurt. Many strains of S. thermophilus produce exopolysaccharides (EPSs) which affect the texture and viscosity of fermented food products. LÄS MER

    Författare :Louise Johansson; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemiteknik och kemisk teknologi; Biokemi; metabolism; Chemical technology and engineering; transcriptome analysis; phosphorus-limitation; carbon-limitation; fed-batch; chemostat; batch; fermentation technology; Escherichia coli; shikimic acid; Biotechnology; Bioteknik; Metabolism; Biochemistry; principal component analysis; 2D-fluorescence spectrophotometry; metabolic flux analysis; carbon-rich;

    Sammanfattning : Shikimic acid production using recombinant E.coli has been developed during the past 15 years due to the increased demand of this product, primarily as a starting material for the anti-influensa medicine Tamiflu?. A detailed metabolic analysis of a shikimic acid producing E. LÄS MER

  4. 3. Low temperature acclimation in plants : alterations in photosynthetic carbon metabolism

    Författare :Maria Lundmark; Vaughan Hurry; Charles Guy; Umeå universitet; []
    Nyckelord :Plant physiology; cold acclimation; carbon metabolism; photosynthesis; respiration; Växtfysiologi; Physiological Botany; fysiologisk botanik;

    Sammanfattning : Although low temperature plays an important role in determining agricultural yield, little is known about the effect on the underlying biochemical and physiological processes that influence plant growth. Photosynthesis and respiration are central to plant growth and both processes are heavily affected by temperature. LÄS MER

  5. 4. Efficient Conversion of Lignocellulose Hydrolysates- Yeast Tolerance and Redox Metabolism

    Författare :Tobias Modig; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metabolism; Biokemi; metabolism; hyperosmotic stress; Biochemistry; S. cerevisiae; anaerobic growth; inhibitor tolerance; furfural; lignocellulose; HMF; Biotechnology; Bioteknik;

    Sammanfattning : The fermentation of lignocellulose hydrolysates by Saccharomyces cerevisiae for ethanol production was investigated. An important problem for the successful conversion of these hydrolysates is that they often are inhibitory. LÄS MER

  7. 5. Engineering central carbon metabolism with phosphoketolase pathways in Saccharomyces cerevisiae

    Författare :John Hellgren; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; precursor supply; transcriptomics; sustainability; non-oxidative glycolysis; Carbon-conservation; metabolic engineering; platform strain; GATHCYC; proteomics;

    Sammanfattning : We need more efficient biocatalysts to make sustainable microbial production of chemicals and fuels more profitable before they can replace petroleum-based sources. Rewiring the metabolic pathways in the biocatalysts to avoid the loss of carbon as CO2 can aid in improving product yields and thereby the profitability of the process. LÄS MER
