  1. 1. Biopolymers processed and used as enzyme carriers

    Master-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Dániel Mészáros; [2023]
    Nyckelord :Biobased materials; plasticized sodium alginate; water stability; extraction kinetics; enzyme carrier; Biobaserade material; Mjukgjort natriumalginat; Vattenstabilitet; extraktionskinetik; Enzymbärare;

    Sammanfattning : Syftet med detta masterprojekt var att undersöka möjligheten att använda biobaserat, mjukgjort natriumalginat (NaAlg) som enzymbärare. Alginaterna görs traditionellt bearbetbara genom att tillsätta olika mjukgörare, såsom polyoler (glycerol, sorbitol, etc.), i detta arbete användes glycerol. LÄS MER

  3. 2. Energy & redox fluxes in Lactobacillus reuteri DSM 17938 on different sugars

    Master-uppsats, Lunds universitet/Teknisk mikrobiologi; Lunds universitet/Bioteknik

    Författare :Katarzyna Bengtsson; [2019]
    Nyckelord :Energy; redox fluxes; Lactobacillus reuteri DSM 17938; different sugars; applied microbiology; teknisk mikrobiologi; Biology and Life Sciences; Chemistry; Technology and Engineering;

    Sammanfattning : Under anaerobic condition the specific growth rate of Lactobacillus reuteri DSM 17938 on different sugars, was analyzed using spectrophotometry. Electron acceptor (fructose) supported cells to cope with poor energy recovery by re-oxidising the NADH, thus enabling ATP formation thru acetate production, while fermenting glucose via the phosphoketolase pathway (PKP) and simultaneously operating via Embden-Meyerhof pathway (EMP).

  4. 3. Kinetic studies of carrier conjugated protease inhibitors

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning; Uppsala universitet/Institutionen för kemi - BMC

    Författare :Enrique Argenis López Olvera; [2019]
    Nyckelord :Proteases inhibitors; bioconjugates; enzyme kinetics; inhibition;

    Sammanfattning : Conjugates of soybean trypsin inhibitor (SBTI) and potato serine protease inhibitor (PSPI) immobilized on metal oxide particles of ~100nm diameter were prepared. Inhibition of trypsin hydrolysis of BAPA by these conjugates was measured and enzyme kinetics constants kcat, KM, kcat/KM and ki were determined. LÄS MER

  5. 4. Phenolic compounds in Fagopyrum sp. grains (buckwheat) : profile, bioactivity and effect of processing

    Kandidat-uppsats, SLU/Department of Molecular Sciences

    Författare :Agnes Wahlsten; [2019]
    Nyckelord :Buckwheat; Fagopyrum esculentum; Fagopyrum tartari- cum; rutin; quercetin; total phenolic content; gluten-free; functional foods; antioxidants;

    Sammanfattning : This study aimed to investigate the health benefits related to chemical com-pounds found in buckwheat cultivars. Factors influencing the presence of bioactive compounds with assumed health effects were examined. Two spe-cies of buckwheat, Fagopyrum esculentum (common buckwheat) and Fag-opyrum Tartaricum (tartary buckwheat) were evaluated. LÄS MER

  7. 5. Hydrogen production in Escherichia coli : Genetic engineering of the formate hydrogenlyase complex

    Master-uppsats, Institutionen för fysik, kemi och biologi; Tekniska högskolan

    Författare :Charlotte Hjersing; [2011]
    Nyckelord :Escherichia coli; Formate hydrogenlyase; Hydrogenase; Oxygen tolerance;

    Sammanfattning : Biofuels that are renewable and environmentally benign constitute an important area of research, as the supply of fossil fuels decreases and the amount of green house gases in the atmosphere increases. Biohydrogen is not as well explored as other biofuels, but its properties render it a promising complement, as it is clean and can be used directly in fuel cells to generate electricity, the only waste products being water and heat.
