  1. 1. Reactors and biosensors for improved microbial degradation of acetonitrile

    University dissertation from Department of Biotechnology, Lund University

    Author : Kristina Håkansson; Lunds universitet.; Lund University.; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biotechnology; Bioteknik; denitrification; nitrification; on-line analysis and control; Clark electrode; biosensor; biofilm process; acetonitrile; microbial degradation;

    Abstract : Biodegradation is becoming an attractive mode of operation for eliminating toxic chemicals released from industrial processes or already present in the environment. One needs, however, not only to identify organisms capable of degrading such chemicals, but also to address the issue of whether these chemicals, after being degraded, will be toxic to the degrading organisms if present in high concentrations.

  2. 2. Phylogenetic characterization of microbial mats and isolation of Thermus spp. and sulfur-oxidizing bacteria from Icelandic hot springs

    University dissertation from Biotechnology, Lund University

    Author : Sigurlaug Skirnisdottir; Lunds universitet.; Lund University.; [2001]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biochemical technology; hot springs; thermophiles; microbial diversity; SSU rRNA; sulfur-oxidizers; Thermus; Biotechnology; Bioteknik; Biochemistry; Biokemi; Metabolism; Biokemisk teknik;

    Abstract : Until recently, the only way to describe microbial communities was by cultivation. This is a major obstacle because typically only a small fraction of the microbes can be cultivated by standard techniques. However, the use of rRNA and molecular phylogenetic techniques has allowed us to bypass this limitation. 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. Sulphur-Utilizing Microorganisms in Biotechnological Applications - Rubber Recycling and Vanadium Reduction

    University dissertation from Katarina Bredberg, Department of Biotechnology, Lund University

    Author : Katarina Bredberg; Lunds universitet.; Lund University.; [2003]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pyrococcus furiosus; Acidithiobacillus; microbial vanadium reduction; microbial detoxification; rubber recycling; devulcanization; Biotechnological desulphurization; waste rubber materials; Biotechnology; Bioteknik;

    Abstract : Popular Abstract in Swedish I slutet på 1400-talet såg Christoffer Columbus, som förste europé, gummi användas av indianerna i Sydamerika. Han tog med sig materialet hem till Portugal, men kunde säkert inte föreställa sig de stora mängder gummi som några hundra år senare skulle komma att användas världen över. READ MORE

  5. 5. Diversity of thermostable DNA enzymes from Icelandic hot springs

    University dissertation from Biotechnology, Lund University

    Author : Sigridur Hjorleifsdottir; Lunds universitet.; Lund University.; [2002]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermophiles; microbial diversity; SSU rRNA; Thermus; hot springs; Biotechnology; Bioteknik; Biochemistry; enzymologi; Proteiner; enzymology; metabolism; Proteins; DNA enzymes; Biokemi;

    Abstract : The diversities of bacteria as well as thermostable DNA enzymes in Icelandic hot springs were studied using different techniques. First of all the bacterial diversity of different microbial mats as well as sediment samples was described by using both molecular methods and cultivation methods. READ MORE
