  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

  2. 2. Heavy Metal Superantigen : Genetic Regulation of Lymphocyte Activation by HgC12

    University dissertation from Stockholm : Stockholm University

    Author : Yun Jiang; Stockholms universitet.; [1998]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Immunology; immunologi;

    Abstract : Injections of subtoxic doses of HgCl2 (mercuric chloride) cause a systemic autoimmune disease in genetically predisposed rats and mice. My work was designed to elucidate how HgCl2 induces lymphocyte activation and how the response to HgCl2 is regulated in susceptible and resistant strains. 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. Structuring empirical knowledge on environmental issues : urban heavy metal metabolism

    University dissertation from Linköping : Linköpings universitet

    Author : Johan Hedbrant; Linköpings universitet.; Linköpings universitet.; [2003]

    Abstract : During the last century, there has been a large import of heavy metals to urban areas. Only a small fraction, about 10%, has reached the biosphere, the rest is still residing in various goods such as cables, construction materials, technical equipment and batteries, which are still in use or abandoned in infrastructure, buildings, households, enterprises and vehicles.

  5. 5. Heavy metal contamination and toxicity Studies of Macroalgae from the Tanzanian Coast

    University dissertation from Stockholm : Botaniska institutionen

    Author : Florence Alex Mamboya; Stockholms universitet.; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Heavy metals; Padina gymnospora; Ulva reticulata; salinity; nutrients; proteins; uptake; growth; Fv Fm; Zanzibar Channel; NATURAL SCIENCES Biology Organism biology Plant physiology; NATURVETENSKAP Biologi Organismbiologi Växtfysiologi; växtfysiologi; Plant Physiology;

    Abstract : Concentrations of various metals are elevated above background levels in several intertidal areas along the Tanzanian coasts. However, there is little available information concerning the toxicity of these metals and how the uptake of these metals by bioindicators are influenced by external factors, such as heavy rains and increased coastal eutrophication, which tend to fluctuate.
