  1. 1. A beta-phosphoglucomutase in carbohydrate metabolism of Lactococcus lactis

    Författare :Ny Qian; Teknisk mikrobiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mykologi; virologi; bakteriologi; Mikrobiologi; mycology; gene regulation; beta-phosphoglucomutase; maltose metabolism; lactate; metabolic engineering; alpha-phosphoglucomutase; Lactococcus lactis; Microbiology; virology; bacteriology; Biochemistry; Metabolism; Biokemi;

    Sammanfattning : Phosphoglucomutase (PGM) catalyzes the reversible conversion of glucose 1-phosphate to glucose 6-phosphate. Two distinct forms of PGM have been purifed and charactierized in Lactococcus lactis growing on maltose: one specific for the alpha-isomer, and the other specific for the beta-isomer of glucose 1-phosphate.

  3. 2. Engineering Saccharomyces cerevisiae for mixed-sugar fermentation

    Författare :Rosa Garcia Sanchez; Teknisk mikrobiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; metabolic engineering; evolutionary engineering; promoter; mixed-sugar utilization; galactose; arabinose; xylose; Saccharomyces cerevisiae; fermentation; ethanol; phosphoglucomutase;

    Sammanfattning : Efficient fermentation of all the monomeric sugars derived from lignocellulose is crucial to increase the economy of bioethanol production, since they can account for a considerable fraction of the fermentable sugars in the raw material. This thesis describes the engineering of Saccharomyces cerevisiae strains for improved xylose, galactose and/or arabinose utilization. LÄS MER

  4. 3. Beta-glucose 1-phosphate interconverting enzymes in Lactococcus lactis: physiological role and regulation in maltose, trehalose and glucose metabolism

    Författare :Ulrika Andersson; Teknisk mikrobiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi; Biochemical technology; Biokemisk teknik; bacteriology; Microbiology; Kemiteknik och kemisk teknologi; Chemical technology and engineering; trehalose 6-phosphate phosphorylase; beta-phosphoglucomutase; maltose phosphorylase; glucose; trehalose; maltose; Lactococcus lactis; beta-glucose 1-phosphate;

    Sammanfattning : Lactic acid bacteria (LAB), including Lactococcus lactis, are abundant in nature. These bacteria convert carbohydrates into mainly lactate by a rather uncomplicated metabolism. An improved understanding of the physiological and genetical mechanisms involved in carbohydrate metabolism and its regulation will improve the industrial use of LAB. LÄS MER

  5. 4. Metabolic Engineering of Disaccharide Catabolism for Polysaccharide Formation in Lactococcus lactis and Streptococcus thermophilus

    Författare :Fredrik Levander; Institutionen för immunteknologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemiteknik och kemisk teknologi; Chemical technology and engineering; metabolic engineering; exopolysaccharide; polysaccharide; disaccharide; Streptococcus thermophilus; lactic acid bacteria; Lactococcus lactis; Biochemical technology; Biokemisk teknik; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : Exopolysaccharides (EPSs) produced by the lactic acid bacteria (LAB) Lactococcus lactis and Streptococcus thermophilus are important for the rheological behaviour and texture of a variety of fermented food products. Furthermore, EPSs from food-grade LAB have potential as food additives and functional food ingredients with both health and economic benefits. LÄS MER

  7. 5. Promiscuity and Selectivity in Phosphoryl Transferases

    Författare :Alexandre Barrozo; Shina Kamerlin; Qiang Cui; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; phosphate chemistry; linear free energy relationships; phosphatase; catalytic promiscuity; empirical valence bond approach; alkaline phosphatase;

    Sammanfattning : Phosphoryl transfers are essential chemical reactions in key life processes, including energy production, signal transduction and protein synthesis. They are known for having extremely low reaction rates in aqueous solution, reaching the scale of millions of years. LÄS MER
