1. 1. Screening of HETP test conditions and resin storage solutions for HIC

   University essay from Uppsala universitet/Analytisk farmaceutisk kemi

   Author : Lise-Lotte Ronnerfors; [2023]
   Keywords : Hydrophobic Interaction Chromatography; Pfizer Health AB; Column packing;

   Abstract : Hydrophobic interaction chromatography (HIC) is a common purification method for biological drug substances. For continuous monitoring the quality of the purification, a column performance test is carried out to test the packing of the resin. READ MORE

3. 2. Methanobacterium cauma sp. nov., a hydrogenotrophic, halotolerant methanogen from an active serpintinization system at Chimaera seep

   University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

   Author : Aubree Stephens; [2023]
   Keywords : methanogen; archaea; hydrogenotroph; halotolerant; Methanobacterium; Chimaera seep; methanogenesis;

   Abstract : The archaeal branch of life represents some of the oldest life forms on Earth. Archaea are believed to have diverged from Prokaryotes roughly 3.5 billion years ago and it’s theorized that biological methane production started around this time as well. This would make methanogenesis one of the oldest metabolisms on our planet. READ MORE

4. 3. Geobacillus 7349 – A new potential biosurfactant producing microorganism

   University essay from Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

   Author : Zhuoying Deng; [2023]
   Keywords : biosurfactant; rhamnolipids; HPLC; HPAEC-PAD; bacteria growth; downstream purification; liquid-liquid extraction; biotechnology; Chemistry;

   Abstract : The main aim of this master project is to find out whether strain Geobacillus 7349 can produce biosurfactant during their growth by extraction and characterization of the product. The other goal is to optimize the cultivation condition of the strain. READ MORE

5. 4. Dependence of Degradation Mechanisms in Magnesium Alloys on Grain Orientation and Interfaces in 3D

   University essay from Lunds universitet/Materialteknik

   Author : Johan Ranstad; [2023]
   Keywords : Mg-Zn alloys; Diffraction contrast tomography; Isothermal Calorimetry; Immersion testing; Corrosion Rate; Microgalvanic coupling.; Technology and Engineering;

   Abstract : Magnesium alloys are promising candidates as biomedical implants. However, a good understanding of their degradation processes is lacking. In this work, degradation in two magnesium alloys were studied in a simple physiological-fluid electrolyte of H2O+0.9wt%NaCl, Mg-5wt%Zn (Z5) & Mg-5wt%Zn-0. READ MORE

6. 5. Influence of Post-treatments on Corrosion Properties of 3D printed Metal Components for Bioprocessing Applications

   University essay from KTH/Materialvetenskap

   Author : Leyla Koort; [2023]
   Keywords : PBF-LB 316L; surface post-treatments; as-built; tumbling; Hirtisation; DLyte; electropolishing; chemical milling; pitting corrosion; CPT; cyclic potentiodynamic polarisation curves; immersion test in 1M NaCl and 1M NaOH;

   Abstract : Additive manufacturing (AM) has the potential to overtake the conventional production of pipe systems of stainless steel grade 316L intended for bioprocessing applications by utilising powder bed fusion laser beam (PBF-LB) technologies. However, challenges such as high surface roughness need to be overcome and corrosion properties improved to meet industry standards. READ MORE
