1. 26. Maturation and Regulation of Cyanobacterial Hydrogenases

   Författare :Åsa Agervald; Peter Lindblad; Karin Stensjö; Ann Magnuson; Poul Erik Jensen; Uppsala universitet; []
   Nyckelord :Biohydrogen; Cyanobacteria; Nostoc sp. PCC 7120; Nostoc punctiforme PCC 73102; Hydrogenase; Maturation; Transcriptional regulation; CyAbrB; CalA; FeSOD;

   Sammanfattning : Accelerated global warming plus an increasing need for energy is an equation not easily solved, thus new forms of sustainable energy production are urgently requested. In this context hydrogen production based on a cyanobacterial system offers an environmentally friendly alternative for energy capture and conversion. LÄS MER

3. 27. Development and Validation of HPLC Methods for Analytical and Preparative Purposes

   Författare :Johan Lindholm; Torgny Fornstedt; Karin Caldwell; Karl-Gustaf Wahlund; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; High performance liquid chromatography HPLC ; Analytical biotechnology; Sample preparation; Diode-array-detection DAD ; Mass spectrometry MS ; Validation; Preparative chromatography; Competitive isotherm parameters; Perturbation peak PP method; Kemi; Chemistry; Kemi;

   Sammanfattning : This thesis concerns the development and validation of high performance liquid chromatography (HPLC) methods aimed for two industrially important areas: (i) analysis of biotechnological synthesis and (ii) determination of adsorption isotherm parameters. There is today a lack of detailed recommendations for analytical procedures in the field of biotechnological production of drugs. LÄS MER

4. 28. Biochemical and Physiological Characterization of Nonsymbiotic Plant Hemoglobins

   Författare :Nélida Leiva; Tillämpad biokemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hemoglobin; Non-symbiotic hemoglobin; Sugar beet; Ligand binding; Nitric oxide; Gene expression; Gene overexpression; Poplar; Arabidopsis; Lepidium campestre.;

   Sammanfattning : Hemoglobins (Hb) are usually associated with blood in humans. However, these proteins are widely distributed among living organisms. In plants the most known group are the leghemoglobins. Still, other Hbs that not participate in symbiosis are also found. LÄS MER

5. 29. Microbial Treatment of Heavy Metal Leachates

   Författare :Teresa Alvarez Aliaga; Bioteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pollution control; Environmental technology; algal-bacterial symbiosis.; metal precipitation; biosorption; biogenic sulphide; municipal and agricultural solid wastes organic matter degradation; sulphate-reducing bacteria; Bioremediation; heavy metals removal; Miljöteknik; kontroll av utsläpp; Biotechnology; Bioteknik;

   Sammanfattning : Ore-mining, metallurgy and other industrial activities represent the source of heavy metal and radionuclide contamination in terrestrial and aquatic environments. Physico-chemical processes are employed for heavy metal removal from industrial wastewater. LÄS MER

7. 30. Separation of biomolecules using Open-Loop Non-Isocratic Simulated moving bed (SMB) technology

   Författare :Deepti Sahoo; Bioteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Open-loop Non-Isocratic SMB; Simulated moving bed; True moving bed Chromatography; continuous separation; protein purification; batch chromatography;

   Sammanfattning : In biotechnological industries, downstream processing is a bottleneck in the complete production process. There is a wish to reduce the costs and therefore one tries to operate separation technology in continuous mode. LÄS MER
