  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. Modelling of a sulfate reducing and metal recovery process, for application within treatment of industrial wastewater

    Master-uppsats, Lunds universitet/Bioteknik (master)

    Författare :Kristina Broberg; [2019]
    Nyckelord :Biotechnology; Wastewater treatment; Process modelling; Bioprocess technology; Sulfate reducing bacteria; Metal sulfides; Simulation; Matlab; SuperPro Designer; Bioteknik; Technology and Engineering;

    Sammanfattning : Denna masteruppsats syftar till utvecklandet av en industriellt, fullskalig modell över en vattenreningsprocess som syftar till simultan sulfatreduktion och tungmetallåtervinning från processvatten vid gruvdrift. Den mängd sulfat som finns tillgänglig i lakvattnet, omvandlas till vätesulfid med hjälp av sulfatreducerande bakterier (SRB). LÄS MER

  4. 4. Optimering av IPC kontroller - Kvalitetssäkring och kostnadseffektivisering

    Master-uppsats, Lunds universitet/Teknisk mikrobiologi

    Författare :Hanna Hovstadius; Moa Engholm; [2019]
    Nyckelord :IPC; In-process Controls; kvalitetssäkring; kostnadseffektivisering; produktionslinjer; munhygienprodukter; bioteknik; biotechnology; teknisk mikrobiologi; applied microbiology; Technology and Engineering;

    Sammanfattning : In-process Controls (IPC) are controls performed to ensure quality in production. At TePe Munhygienprodukter AB (TePe) there was a need to evaluate, analyze and optimize the IPC:s in their production which was the motivation for this master thesis. LÄS MER

  5. 5. Optimising IPTG and Lactose Induction of Recombinant Expression with Flow-based Online Analysis

    Master-uppsats, Lunds universitet/Bioteknik (master)
