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

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

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

   Sammanfattning : 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. LÄS MER

3. 17. Recovery of Dialcohol Cellulose using Micro- and Ultrafiltration Processes

   Master-uppsats, Lunds universitet/Kemiteknik (CI)

   Författare :Lina Näslund; Gabriella Petersson; [2023]
   Nyckelord :Membrane filtration; Ultrafiltration; Microfiltration; Dialcohol cellulose; DAC; Bioplastics; Chemical engineering; Process design; Technology and Engineering;

   Sammanfattning : The waste management and production of plastic play a concerning part in global warming and continues to have a negative effect on the environment. A promising strategy to address this challenge is to develop new sustainable materials, to replace current fossil-based plastics. LÄS MER

4. 18. Concentration of Proteins and Decrease of Salt Content in a Hydrolyzed Fermentation Broth Using Membrane Filtration

   Master-uppsats, Lunds universitet/Kemiteknik (CI)

   Författare :Linnea Sjökvist; [2023]
   Nyckelord :Membrane filtration; ultrafiltration; PHA; polyhydroxyalkanoates; chemical engineering; Technology and Engineering;

   Sammanfattning : Membrane filtration was used to concentrate proteins and decrease the salt concentration in a hydrolyzed fermentation broth. The broth was a by-product from the bacterial production and extraction of polyhydroxyalkanoates (PHA), that can be used to produce biobased plastics. LÄS MER

5. 19. Combustibility study of resin for warm magnet coils used at CERN

   Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

   Författare :Juan Carlos Lopez Santiago; [2023]
   Nyckelord :Epoxy resin; flammability; radiation; aging; cone calorimeter; micro combustion calorimeter; thermogravimetric analysis; lateral ignition and flame spread test; chemical composition of polymers; polymers; epoxy composite; polymer composite; failure of epoxy resins; magnetic coil; Technology and Engineering;

   Sammanfattning : CERN is the world's largest particle physics laboratory, housing multiple accelerators that rely heavily on magnetic coils. These coils are integral to the generation of powerful magnetic fields essential for particle accelerator experiments, detectors, and other equipment. LÄS MER

7. 20. Finding ways of optimizing coagulant dosage, for a more sustainable wastewater treatment process

   Master-uppsats, Lunds universitet/Kemiteknik (CI)

   Författare :Hanna Sjöman; [2023]
   Nyckelord :Wastewater treatment process; coagulant dosage; COD; machine learning; water and environmental engineering; Technology and Engineering;

   Sammanfattning : The wastewater treatment process at Oatly consists of several treatment steps of which, two are chemical treatment steps involving coagulation followed by flotation to remove phosphorous and COD. The coagulant dosage is mainly determined based on the operator’s experience and supported using results from jar tests. LÄS MER
