1. 21. Remediation of per- and polyfluoroalkyl substances (PFAS) in contaminated water by sorption to pine- and spruce bark

   University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

   Author : Rebecka Ayranci Dahlberg; [2023]
   Keywords : Per- and polyfluoroalkyl substances; sorption; pine bark; spruce bark; ultra-short-chain PFAS; short-and long-chain PFAS; elemental analysis; field-test;

   Abstract : PFAS are anthropogenic substances used in many different industrial operations and products because of their unique properties. Due to their negative impact on human health and environmental bioaccumulative characteristics different authorities have addressed the issue. In Sweden the limit is4 ng/L for four different PFAS in drinking water. READ MORE

3. 22. Characterization of potato protein and its calcium binding capacity

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

   Author : Signe König; Erika Thomson; [2023]
   Keywords : Patatin; Calcium; Food supplement; Calcium Assay; Alcalase; potato protein; Applied biochemistry; Biology and Life Sciences; Technology and Engineering;

   Abstract : Calcium is essential for the human body as it has functions in the nervous system, bones and formation of teeth. Deficiency in this important nutrient can be detrimental to health and cause life-long issues. Calcium can be found in various foods, like dairy products, but certain plant-based alternatives to milk needs to be fortified with calcium. READ MORE

4. 23. Optimization of two high-performance size-exclusion chromatography methods with diode-array detection for protein quantification and purity assessment

   University essay from Lunds universitet/Centrum för analys och syntes

   Author : Camilla Lane; [2023]
   Keywords : Method qualification; Protein concentration; Protein Purity; High Performance Size exclusion chromatography; Quality control; Analytical chemistry; Biology and Life Sciences;

   Abstract : Background: There is a need to develop methods of determining concentration and purity for two new affinity ligands, protein T and protein H, in order to ensure the quality of an industrial production of said proteins. Aims: To develop a High Performance Size Exclusion Chromatography, HPSEC, method to determine concentration and purity of protein T and to improve an existing HPSEC method for concentration and purity determination of protein H that show selectivity, display linearity between peak area and injection amount and give repeatable results.

5. 24. Towards time-resolved cryo-EM of SARS-CoV-2 replication-transcription complex and Staphylococcus aureus DNA gyrase

   University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

   Author : Anna Králová; [2023]
   Keywords : time-resolved cryo-EM; DNA gyrase; SARS-CoV-2; replication-transcription complex; protein purification;

   Abstract : Time-resolved cryo-EM has already provided ground-breaking discoveries in various fields, including structural biology, biochemistry, and drug development. Compared to traditional structural biology methods where mostly stabilized conformations are reconstructed, the main advantage of time-resolved cryo-EM is its ability to capture dynamic processes in biological samples at near-atomic resolution, which allows for studying biological structures as they change and interact in real-time.

6. 25. Cultivation of Yarrowia lipolytica on a hydrolysate based on food waste

   University essay from SLU/Department of Molecular Sciences

   Author : Hanna Norrman; [2023]
   Keywords : Yarrowia lipolytica; hydrolysate; food waste; fish feed; volatile fatty acids;

   Abstract : Interest in replacing fish oil and fish meal as fish feed ingredients with more socially, environmen-tally, and economically sustainable alternatives has increased in recent years. One such alternative could be the use of yeast biomass. READ MORE
