1. 1. Optical manipulation and spectroscopy of single functional globin-containing cells in microfluidic systems

   Författare :Kerstin Ramser; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heme-proteins; optical manipulation; resonance Raman spectroscopy; microfluidic systems; single cells; Medical Engineering for Healthcare;

   Sammanfattning : Recent advances in microbiology and biomedicine require development of tools to monitor the response of single cells to environmental stimuli under controlled physiological conditions. In this thesis, I describe how this can be achieved by combining various spectroscopic techniques with optical tweezers and microfluidic systems. LÄS MER

3. 2. Heme Protein Biogenesis - Catalase in Enterococcus faecalis

   Författare :Michael Baureder; Molekylär cellbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Enterococcus faecalis; heme proteins; protein assembly; oxidative stress; catalase; cytochrome;

   Sammanfattning : Heme proteins form a large and diverse group of proteins which are involved in a variety of biological functions. The heme prosthetic group enables them to carry out redox reactions, transport electrons, bind gaseous molecules, and function as sensors. Despite their importance only little is generally known about heme protein biogenesis. LÄS MER

4. 3. Raman and Fluorescence Spectroscopy of Single Molecules and Metal Particles

   Författare :Jerk Bjerneld; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; laser-induced; single-molecule spectroscopy; surface-enhanced Raman scattering; nanoparticles;

   Sammanfattning : Technological and conceptual advances have led to the realization of single-molecule spectroscopy. This permit detailed investigations of heterogeneous systems in fields ranging from condensed matter physics to biochemistry. It was recently discovered that surface-enhanced Raman scattering (SERS) can be used to study single molecules. LÄS MER

5. 4. Extracellular electron transfer features of the Gram-positive bacterium Enterococcus faecalis

   Författare :Galina Pankratova; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Gram-positive bacteria; Enterococcus faecalis; Extracellular electron transfer; Electron-conducting redox polymers; Mediated electron transfer;

   Sammanfattning : Electroactive microorganisms possess the unique ability to transfer electrons to or from a solid phase electron conductor, e.g., electrodes or minerals, through various physiological mechanisms. LÄS MER

7. 5. Protein isolation from herring (Clupea harengus) using the pH-shift process - Protein yield, protein isolate quality and removal of food contaminants

   Författare :Sofia Marmon; Chalmers tekniska högskola; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; precipitation; acid; gelation; in vitro digestion; solubilization; herring; protein; salt solubility; pH; lipids; alkaline; transmission electron microscopy; dioxins;

   Sammanfattning : Herring (Clupea harengus) contain valuable proteins but is difficult to process into high-quality foods due to its small size and high content of bones, heme-proteins and lipids. Herring is among the most abundant fish species in the world, but is currently utilized largely for fish meal and oil production. LÄS MER
