  1. 1. Engineering of Human Fetal Hemoglobin

    Författare :Karin Kettisen; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fetal hemoglobin; protein engineering; recombinant protein production; protein purification; chromatography; oxygen carrier; redox reactions; net surface charge; DNA cleavage;

    Sammanfattning : In blood, the oxygen-transporting protein hemoglobin (Hb) governs the oxygenation of cells and tissues. Naturally, this protein has claimed a place in the center of the research field of artificial oxygen therapeutics. LÄS MER

  3. 2. Fermentation of wheat starch hydrolysate by Lactococcus lactis: Factors affecting product formation

    Författare :Karin Hofvendahl; Teknisk mikrobiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nutrients; temperature; pH; optical isomers; maltose; wheat; starch hydrolysate; Lactococcus lactis; lactic acid; SSF; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : Lactic acid exists as two optical isomers, D- and L-lactic acid. For the production of biodegradable poly-lactic acid an optically pure product is desirable, but a racemate of known and constant ratio can also be used. Lactic acid can be produced either synthetically or fermentatively. LÄS MER

  4. 3. The effect of sequence truncation and amino-acid substitutions on the biophysical properties of protein S and calbindin D9k

    Författare :Karin Julenius; Biofysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; surface plasmon resonance; fluorescence spectroscopy; circular dichroism spectroscopy; NMR spectroscopy; hydrophobic effect; protein stability; dimerization; cooperativity; calcium binding; EGF-module; EF-hand; calbindin D9k; protein S; synthet; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : Protein S is a modular protein and a cofactor in the protein C anticoagulant system. It consists of a Gla-module, a thrombin-sensitive loop, four EGF-modules and a SHBG-like module. LÄS MER

  5. 4. The GRE3 encoded aldo-keto reductase and its influence on xylose fermentation in recombinant Saccharomyces cerevisiae strains

    Författare :Karin Träff; Teknisk mikrobiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biochemical technology; Biokemisk teknik; dihydroxyacetone phosphate; xylose reductase; xylose; xylose isomerase; GRE3; Saccharomyces cerevisiae; aldo-keto reductase;

    Sammanfattning : The aim of the work presented in this thesis was to improve ethanol formation from xylose in recombinant Saccharomyces cerevisiae strains. This was achieved by decreasing the xylitol by-product formation. Gre3p is the major xylose-reducing enzyme in S. cerevisiae. LÄS MER

  7. 5. Physiology of Caldicellulosiruptor saccharolyticus: a hydrogen cell factory

    Författare :Karin Willquist; Teknisk mikrobiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; growth activation; hydrogen tolerance; hydrogen yields CO2 inhibition; physiology; enzyme kinetics; Caldicellulosiruptor saccharolyticus; biohydrogen; energy metabolism;

    Sammanfattning : A high substrate conversion efficiency is a prerequisite for an economically feasible biohydrogen production. Caldicellulosiruptor saccharolyticus is a strictly anaerobic extreme thermophilic bacterium that is able to convert the theoretical maximum of 4 mol/mol glucose to H2. LÄS MER
