1. 21. Novel reagentless electrodes for biosensing

   Författare :Alina Sekretaryova; Mats Eriksson; Mikhail Vagin; Anthony Turner; Sergey Shleev; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Analytical chemical information is needed in all areas of human activity including health care, pharmacology, food control and environmental chemistry. Today one of the main challenges in analytical chemistry is the development of methods to perform accurate and sensitive rapid analysis and monitoring of analytes in ‘real’ samples. LÄS MER

3. 22. Mechanistic design of structural elements controlling proton pumping in cytochrone c oxidase

   Författare :Håkan Sigurdson; Michael T. Wilson; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biogeochemistry; biogeokemi;

   Sammanfattning : Cytochrome c oxidase is the last component of the respiratory chain in mitochondria and many bacteria, where it catalyses the reduction of O2 to water. The structures of cytochrome c oxidases from a number of organisms such as bacteria and cow, are known and show remarkable similarities in both structure and function. LÄS MER

4. 23. Genes for cytochrome c and cytochrome c oxidase synthesis in Bacillus subtilis

   Författare :Jenny Bengtsson; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Microbiology; cytochrome; cytochrome c oxidase; Bacillus subtilis; cytochrome c synthesis; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

   Sammanfattning : Cytochromes are heme-containing proteins that function in electron transfer reactions, e.g. respiration and photosynthesis. There are several different types of cytochromes. LÄS MER

5. 24. Sensor Systems for Bioprocess Monitoring

   Författare :Helena Lidén; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; on-line; pattern recognition; gas sensor array; electronic nose; monosaccharides; ethanol; biosensor; carbon paste electrode; Analytical chemistry; Analytisk kemi;

   Sammanfattning : Two different detection methods for on-line monitoring of substrates and products in ethanol fermentations have been studied. Amperometric biosensors were developed for use as detectors in flow injection or liquid chromatographic (LC) systems. LÄS MER

7. 25. Vitreoscilla hemoglobin. In vitro mutagenesis and transcript profiling to improve its biotechnological usefulness

   Författare :Charlotte Andersson; Tillämpad biokemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemical technology; Biokemisk teknik; gene expression analysis; transcript profiling; microarray; DNA chips; microaerobic; hypoxia; oxygen-limited; bacterial hemoglobin; Escherichia coli; Vitreoscilla hemoglobin VHb ;

   Sammanfattning : Vitreoscilla is an obligate aerobic bacterium found in oxygen-poor environments such as stagnant ponds and decaying vegetable matter. Vitreoscilla induces the production of a homodimeric hemoglobin (VHb) when subjected to oxygen-limiting conditions. LÄS MER
