  1. 1. Cloning and expressing the genes encoding Glycerol dehydratase (GDHt) and 1,3-Propanediol dehydrogenase (1,3-PDDH) in E. coli

    University essay from Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

    Author : Eleni Pechlivani; [2023]
    Keywords : 1; 3-Propanediol; Glycerol dehydratase; 3-Propanediol dehydrogenase; Glycerol dehydratase reactivase; E. coli; Protein expression; Biotechnology; Technology and Engineering;

    Abstract : The biodiesel sector has witnessed tremendous growth in recent years, leading to a significant increase in glycerol production as a by-product. Addressing the challenge of glycerol valorization is crucial for the sustainability of the biodiesel industry. READ MORE

  3. 2. Synthesis and Investigation of Nitrile-Containing Polymers Inspired by Lignin

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Tobias Lindborg; [2022]
    Keywords : Lignin; Polymer; Renewable; Bioresource; Glass transition temperature; Nitrile; Polymer technology; Chemistry; Technology and Engineering;

    Abstract : The lignin-inspired derivatives coniferyl aldehyde and sinapyl aldehyde were used to prepare nitrile-containing methacrylate monomers with the aim to synthesize bio-based polymers exhibiting high glass transition temperatures (Tgs). The aldehydes were initially transformed to the corresponding nitriles and then underwent methacrylation before being polymerised by free-radical polymerisation. READ MORE

  4. 3. Ozone oxidation of fatty acid thin films: a TIR Raman study

    University essay from KTH/Yt- och korrosionsvetenskap

    Author : Frida Preuss; [2022]
    Keywords : ozone oxidation; TIR Raman; fatty acid; vibrational spectroscopy; thin film formation; ozonoxidation; TIR Raman; fettsyra; vibrationsspektroskopi; skapande av tunna filmer;

    Abstract : Detta examensarbete initierades och handledes av Mellifiq, ett företag som arbetar med rening av luft och vatten, där en applikation är rening av köksfrånluft med ozon. Ozon förhindrar att fettpartiklar i frånluften ansamlas på väggarna i kanalen och värmeväxlaren, vilket leder till högre brandsäkerhet och mer effektiv användning av värmeväxlaren. READ MORE

  5. 4. Evaluation of the stability of immobilized lipases from Rhizomucor miehei and Rhizopus oryzae in high oleic sunflower oil

    University essay from Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

    Author : Jinxu Xu; [2021]
    Keywords : lipase; immobilization; oxidation; biotechnology; Technology and Engineering;

    Abstract : Lipase is one of the most useful enzymes in food industry, which can catalyze the hydrolysis and the synthesis of esters. However, the high cost due to the poor operation stability of lipase hinders the wide use of it. READ MORE

  6. 5. Aroma components of long ripened cheese and their origin, variation and contribution to flavour : with focus on propionic acid

    University essay from SLU/Department of Molecular Sciences

    Author : Sandra Carlsson; [2021]
    Keywords : cheese ripening; aroma components; volatile compounds; metabolism of lactose; lactate and citrate; ; proteolysis; lipolysis; propionic acid bacteria; sensory evaluation;

    Abstract : Flavour compounds in cheese are formed by metabolism of residual lactose, lactate and citrate, proteolysis and lipolysis through the activity of e.g., starter bacteria. Generally identified aroma components in cheese are fatty acids, esters, alcohols, ketones, lactones, aldehydes, and sulphur compounds. READ MORE
