1. 1. 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. 2. Killer action of Spok homologue in Fusarium vanattenii : Investigation through site directed mutagenesis

   University essay from Uppsala universitet/Institutionen för organismbiologi; Uppsala universitet/Institutionen för biologisk grundutbildning

   Author : Samuel Jorayev; [2023]
   Keywords : Spok genes; FuSpok; Meiotic Driver; Fusarium; transposons;

   Abstract : The Spok genes are a group of selfish genetic elements in the fungus Podespora anserina which kills spores lacking them. These Spoks function through a toxin and resistance domain. Homologues of these have been found across other species such as in the Fusarium genus. READ MORE

4. 3. Temperaturens inverkan på tillväxt av olika mikroorganismer på frysta livsmedel

   University essay from SLU/Department of Molecular Sciences

   Author : Almohannad Alahmad; [2022]
   Keywords : Frysning; ; förskämning; hållbarhet; mikroorganism; upptining;

   Abstract : Metoder för att bevara mat har varit en viktig aspekt för att säkra livsmedelsförsörjningen genom historien. Frysning och andra konserveringsmetoder har använts med framgång under årens lopp för att förlänga livsmedels hållbarhetstid, men det finns ibland mikroorganismer på livsmedel som kan växa till mängder som kan leda till sjukdom och utgöra problem för individers hälsa, eller så kan de förskämma livsmedel.

5. 4. Analysis of the water quality dynamics of Lake Vomb; Interactions between water quality profile and cyanobacterial bloom in a eutrophic lake in Sweden

   University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

   Author : Wiebke Coenen; [2022]
   Keywords : Vombsj¨on; Lake profile; Cyanobacteria; Drinking water; Random Forest; Technology and Engineering;

   Abstract : Lake Vomb, located in Sk˚ane, Sweden, provides water for groundwater infiltration, used for the drinking water supply of several municipalities, including Malm¨o. The lake is in a bad ecological condition with intense algae blooms during summer. Cyanobacteria dominate mentioned blooms in 2021 posing the threat of releasing cyanotoxins. READ MORE

6. 5. Genomic comparison of shiga toxin-producing E. coli O157:H7 from ruminants and humans

   University essay from Uppsala universitet/Institutionen för medicinsk biokemi och mikrobiologi

   Author : Linnéa Good; [2022]
   Keywords : ;

   Abstract : Shiga toxin-producing E. coli (STEC) are zoonotic pathogens that frequently colonise ruminants without them showing any symptoms. In humans, STEC cause diarrhoeal disease and occasionally leads to the life-threatening disease haemolytic-uraemic syndrome (HUS). READ MORE
