1. 21. EXPRESSION OF SUGAR BEET HEMOGLOBIN IN PICHIA PASTORIS

   University essay from Lunds universitet/Tillämpad biokemi; Lunds universitet/Beräkningskemi

   Author : Johan Pettersson; [2022]
   Keywords : Pichia pastoris; expression; sugar beet; hemoglobin; km71; ppic9; ppic3.5; phil-s1; applied biochemistry; Biology and Life Sciences;

   Abstract : People who don’t eat meat can suffer from iron deficiency due to the lower efficiency of absorption of non-heme iron compared to heme iron. The aim of this master thesis was to explore the possibilities of producing a plant-based alternative of heme-iron by evaluating the efficiency of expression of sugar beet hemoglobin in the methylotrophic yeast Pichia pastoris.

3. 22. Potential of waste-derived VFAs-bearing effluents as an external carbon source for MBBR denitrification of domestic wastewater

   University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

   Author : Seyed Reza Manafi Khosroshahi; [2022]
   Keywords : Volatile fatty acids; Denitrification; Wastewater treatment; Biological nutrient removal; Nitrate removal; Electron accepter; Carbon source; Electron doner; Moving bed biofilm reactor; Nanofiltration; VFA concentration; Discharge standards; Carriers; acclimatization; VFAs; MMBR; NF; WWTP; BNR;

   Abstract : In conventional wastewater treatment plants, methanol, ethanol, and acetate are used as carbon source for the denitrification process in the biological nutrient removal. However, growing concern regarding economical costs and carbon footprints from the fossil-based production of these chemicals have forced the companies to look for other alternatives. READ MORE

4. 23. Post-Denitrification on Sand Filter at Bromma Wastewater Treatment Plant

   University essay from KTH/Kemi

   Author : Emil Blocksjö; [2022]
   Keywords : Sand filter; Post-Denitrification; Nitrate; Nitrification; Wastewater; Sandfilter; Efterdenitrifikation; Nitrat; Nitrifikation; Avloppsvatten;

   Abstract : Examensarbetets syfte var att undersöka möjligheter till denitrifikation på sandfilter (SF) i industriell skala och hur det jämför sig med konventionella metoder för att uppnå denitrifikation och effekten av förändringen på processen vid Bromma reningsverk. Parametrar som undersöktes var rening av ammonium och nitrat, luftning, temperatur, pH, rening av fosfor, rening av organiskt material, rening av suspenderat material, förbigång av vatten vid SF och aktivslamanläggning (ASA), drifttider för SF:arna och total vattenbelastning på ASA och SF.

5. 24. Modification of lignin derivatives for polymerization in water

   University essay from KTH/Ytbehandlingsteknik

   Author : Adrian Södergren; [2022]
   Keywords : biobased monomer; ferulic acid; radical polymerization; styrenic mononer; lignocellulose; biobaserad monomer; ferulsyra; radikalpolymerisation; styrenliknande monomer; lignocellulosa;

   Abstract : För att möjliggöra en hållbar utveckling skiftar många polymerforskares fokus just nu från att syntetisera polymerer från fossila resurser till att producera biobaserade polymerer från exempelvis träd. Av särskilt intresse är lignin, som utgör ungefär en tredjedel av allt växtmaterial men i nuläget oftast används som bränsle. READ MORE

6. 25. Alternative fuels for Swedish short sea shipping and inland waterways: Techno-economic study

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Julien Maszelin; [2022]
   Keywords : Alternative fuels Comparison Short sea shipping Inland waterways Sweden Biofuels Fischer-Tropsch Methanol Hydrogen Ammonia Fossil fuels Sustainable transportation;

   Abstract : Climate change is raising huge challenges for all industries worldwide. It is mainly due to anthropogenic activity and energy consumption which is the cause for emissions of greenhouse gas (GHG) among other environmental impacts and is expected to have huge impact on our societies globally.
