  3. 2. Production and analysis of novel disulfide variants of Subtilisin Carlsberg

    University essay from Linköpings universitet/Kemi

    Author : Anton Elfstrand; [2023]
    Keywords : Subtilisin Carlsberg; Disulfide; Protein Engineering; Kinetic Stability;

    Abstract : Protein engineering has been used to alter the stability of proteins for several decades withmuch success, one approach being to introduce two cysteine residues that together form adisulfide bridge. The disulfide bridge can increase the Gibbs free energy of the transitionstate, thus increasing energy difference between the folded state and the unfolding transitionstate, leading to increased kinetic stability of the protein.

  4. 3. Profitability of optimizing biogas production in dairy farms : an experimental case study of a Swedish dairy farm´s usage of nitrogen in digestate as a nutrient resource for crop production

    University essay from SLU/Dept. of Economics

    Author : Nils Hermansson; Albin Åkerblom; [2023]
    Keywords : biogas; optimization; profitability; economic effects; organic; conventional; agriculture; dairy farms; digestate; nitrogen; biogas; optimering; lönsamhet; ekonomiska effekter; ekologiskt; konventionellt; lantbruk; mjölkgårdar; rötrester; kväve;

    Abstract : Biogas has the potential to be a contributor to sustainable energy for electricity, fuel, and heating. Because of that, there are different alternatives for biogas plants. In this study, a farm-based biogas plant for electricity production has been of interest. READ MORE

  5. 4. Biogas Potential in the North of Sweden : Inventory and Techno-Economic Assessment of Substrates for an Increased Biogas Production in Norrbotten

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Alma Fahlén Hammar; [2023]
    Keywords : Biogas; anaerobic digestion; AD; Norrland; bioenergy; fossil-free; chemical engineering; Chemistry; Technology and Engineering;

    Abstract : Great investments are planned in the north of Sweden the coming years, not the least in the county of Norrbotten where the projects collectively are referred to as the green transition due to the focus on fossil-free techniques. But to be able to secure a sustainable energy supply and reach the goal set by the member states of the European Union of a carbon dioxide neutral union in 2050 the production of alternative energy sources needs to intensify.

  6. 5. How the Choice of Primary Treatment Affects the Biogas Potential of Primary Sludge

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Fanny Blom; [2022]
    Keywords : wastewater treatment; primary treatment; biogas potential; primary settling treatment; rotating belt filter; chemically enhanced primary treatment; environmental engineering; water resources engineering; Technology and Engineering;

    Abstract : The global heating has resulted in rising temperatures and more extreme weather conditions around the world. In combination with increasing energy demands, this has led to an increasing demand of renewable energy. One option is utilizing the wastewater to produce biogas. There-fore, wastewater can be seen as a resource rather than waste. READ MORE
