  1. 1. 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).

  2. 2. Development of a Water Activity Control and Reaction Monitoring System for Acidolysis and Transesterification Reactions using Immobilized Lipases in a Rotating Bed Reactor

    Master-uppsats, Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

    Författare :Eimantas Gladkauskas; [2019]
    Nyckelord :Enzyme; Enzymes; Immobilized enzyme; bioreactor; rotating bed reactor; acidolysis; transesterification; arduino; water activity; thermodynamic water activity; Enzyme activity; automatic reaction tracking; reaction tracking; biotechnology; electrical engineering; relative humidity; spinchem; enzymatic synthesis; water activity control; process automation; lipases; lipase; bioteknik; Technology and Engineering;

    Sammanfattning : Controlled water activity in an enzymatic reaction can influence enzyme activity and productivity. A small layer of water around an enzyme gives it a required flexibility to catalyze reactions at a higher rate in contrast with the one that is dry (Adlercreutz, Dicko, Larsson, & Månsson, 2017).

  3. 3. Exploring amino acid metabolism in Saccharomyces cerevisiae for improved eco-efficient production of chiral amine

    Kandidat-uppsats, Malmö universitet/Hälsa och samhälle

    Författare :Anna Karlsson; [2019]
    Nyckelord :1-methyl-3-phenylpropylamine; amino acid; aminotransaminase; biotransformation; chiral amine; metabolically engineered; saccharomyces cerevisiae;

    Sammanfattning : Kirala aminer används idag både som aktiva substanser och som bindningsmedel i flertalet läkemedel, dock är dagens produktion med kinetic resolution ineffektiv vilket gör att mer effektiva och miljövänliga produktionssätt eftersträvas. Biotransformation har visat sig både vara miljövänligt och en effektiv metod för att producera kirala aminer. LÄS MER

  4. 4. Purification and refolding of a novel dipeptidyl peptidase III

    Kandidat-uppsats, Linköpings universitet/Kemi

    Författare :Lennie Jansson; [2019]
    Nyckelord :dipeptidyl peptidase III; DPP III; purification; refolding; protein; Arg-Arg-2NA;

    Sammanfattning : There is a continuous search for novel enzymes to complement the abilities of today’s commercially available enzyme and find tailor-fit alternatives to suit the diverse array of bio-based industries. One application could be to increase biogas yield by finding substrate degrading proteases that can be added to the anaerobic digestion process and survive degradation themselves. LÄS MER

  5. 5. Developing microscopy methods for evaluating bio-processed Brewers Spent Grain (BSG)

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Sera Susan Jacob; [2019]
    Nyckelord :microstructure; CLSM; immuno-labelling; β- glucan; arabinoxylan; cell wall; EPS; food technology; livsmedelsteknologi; Agriculture and Food Sciences;

    Sammanfattning : Spent grain (BSG) is the solid residue obtained during brewing containing leftover malt and adjuncts. Though nutrient-dense, it is found to negatively impact texture and colour when used its raw form as an ingredient in food. LÄS MER
