1. 21. Characterization of Mitilysin Pores by Cryo-electron Microscopy

   University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

   Author : Vladimir Novakovic; [2023]
   Keywords : Mitilysin; Mly; Structural Biology; Cryo-EM; pore; toxin; pore forming proteins; pore forming toxins; PFP; PFT;

   Abstract : Pore forming toxins (PFTs) are a large group of proteins found mainly in bacteria with some exceptions found in animals. They bind and form pores in their target membranes and form pores, which leads to cell death. Among these are cholesterol-dependent cytolysins (CDC), which require the presence of cholesterol to bind target membranes. READ MORE

3. 22. Anaerobic cellulose degrading bacteria isolated from biogas plants

   University essay from SLU/Department of Molecular Sciences

   Author : Caroline Sjöberg; [2023]
   Keywords : anaerobic bacteria; biogas; cellulose; cellobiose; VFA; enzyme activity; TRFLP;

   Abstract : Two cellulose degrading bacteria, named BCISO-4 and DC1-18-4, were isolated from samples retrieved from two large scale biogas-plants. In order to investigate and determine information regarding their growth preferences multiple tests were performed. READ MORE

4. 23. Insulated Metabolic Exchange for Sustainable Agriculture and Biotechnology

   University essay from KTH/Industriell bioteknologi

   Author : Ellen Engquist; [2023]
   Keywords : Biofertilisers; nitrogen; cyanobacteria; E. coli; allantoin; Biogödsel; kväve; cyanobakteria; E. coli; allantoin;

   Abstract : Mellan 1960 och idag har världspopulationen dubblerats medan matproduktionen tredubblats. Det har möjliggjorts av kemiskt framställda gödsel som introducerades på mitten av 1900-talet. Sedan 1965 har användandet av kvävegödsel ökat sexdubblet. READ MORE

5. 24. Study of mixing and exchange in a drinking water reservoir using CFD modeling

   Author : Nadja Rabizadeh; [2023]
   Keywords : CFD; Fluid Mechanics; OpenFOAM; drinking water reservoir; URANS; transient; exchange of water; mixing; Norrvatten;

   Abstract : This thesis examines water mixing and exchange in a drinking water reservoir operated by themunicipal association Norrvatten. Recent water samples from the reservoir’s outgoing waterhave shown an increase in culturable bacteria during late summer and fall. READ MORE

6. 25. Avelsarbetets roll i kampen mot antibiotikaresistenta bakterier : hur kan avel och genredigering reducera behovet av antibiotikatill produktionsdjur?

   University essay from SLU/Dept. of Animal Breeding and Genetics

   Author : Ebba Gustafsson; [2023]
   Keywords : antibiotikaresistens; avel; husdjur; selektion; bakteriell infektion; infektionsresistens; infektionstolerans; genredigering; genetisk markör; genom; CRISPR;

   Abstract : Antibiotikaresistenta bakterier utgör ett globalt hot för både sjukvård och livsmedelsproduktion då de begränsar möjligheten att behandla bakterieinfektioner hos både människor och djur. Förekomsten av resistenta bakterier växer globalt till följd av överflödig och felaktig användning av antibiotikapreparat. READ MORE
