  1. 1. Metal Affinity Peptides in Biotechnological Applications As tools in protein purification, protein stabilisation, metal quantification and metal tolerance of bacteria and plants

    University dissertation from Center for Chemistry and Chemical Engineering

    Author : Malin Mejàre; Lunds universitet.; Lund University.; [2000]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cadmium; metal quantification; fusion tag; metal affinity tag; phage display; peptide library; metal tolerance; metal resistance; metal accumulation; bioremediation; transgenic plant; tobacco; potato; protein purification; immobilised metal affinity chromatography; metal affinity precipitation; metal detection; protein stabilisation; Bioteknik; Biotechnology; Biokemi; Metabolism; Biochemistry; metal ion;

    Abstract : Metal affinity tags have been fused to proteins and demonstrated to function as tools in protein purification, protein stabilisation, quantitative metal analysis and metal tolerance of bacteria and plants. In biotechnological applications proteins frequently have to function in nonnatural environments with harsh conditions which impose requirements for high stability on the proteins. READ MORE

  3. 3. Microbial Treatment of Heavy Metal Leachates

    University dissertation from Department of Biotechnology, Lund University

    Author : Teresa Alvarez Aliaga; Lunds universitet.; Lund University.; [2005]
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 4. Specific Precipitation of Biomolecules Using Synthetic Polymers

    University dissertation from Per-Olof Wahlund, Dept. of Biotechnology, Lund University

    Author : Per-Olof Wahlund; Lunds universitet.; Lund University.; [2003]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biotechnology; Polymerteknik; RNA; plasmid DNA; DNA; polyelectrolyte complexes; synthetic polymers; precipitation; affinity precipotation; Bioteknik; Polymer technology; biopolymers;

    Abstract : Purification is a very important stage in biotechnological processes. The traditionally used precipitation techniques are generally nonspecific and thus one or more chromatographic steps are normally required. There is thus a need for new approaches to improve existing techniques. READ MORE

  5. 5. Calcium Carbonate Precipitation in Presence of Carboxylic Acids

    University dissertation from Stockholm : Kemiteknik

    Author : Karl-Johan Westin; KTH.; [2003]
    Keywords : calcium carbonate; precipitation; crystallization; carboxylic acids;

    Abstract : With a metal removal process based on precipitation aimed atthe purification of pulping effluent as a starting point, theinfluence of carboxylic acids on calcium carbonateprecipitation has been studied. The chosen carboxylic acids canact as more or less strong complexing agents for aqueouscalcium, just as many compounds found in pulping liquors. READ MORE
