  3. 2. Microbial diversity in Baltic Sea sediments

    Författare :Anna Edlund; Janet K. Jansson; Södertörns högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Havsbottnen; Mikroorganismer; Östersjö- och Östeuropaforskning; Baltic and East European studies;

    Sammanfattning : This thesis focuses on microbial community structures and their functions in Baltic Sea sediments. First we investigated the distribution of archaea and bacteria in Baltic Sea sediments along a eutrophication gradient. LÄS MER

  4. 3. Electroremediation of contaminated soil

    Författare :Pascal Suèr; Bert Allard; Lisbeth M. Ottosen; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; electrokinetic remediation; contaminated soil; mercury; heavy metals; organic compounds; Chemistry; Kemi; Enviromental Science; Miljövetenskap;

    Sammanfattning : Electroremediation was applied to contaminated soils in order to study the transport of metals and organic compounds by the external electric field. The electric field caused acidic conditions near the anode, so that copper, zinc, lead, nickel, cadmium, calcium and manganese were released from soil from a chlor-alkali site. LÄS MER

  5. 4. Fungal Redox Enzymes Involved in the Oxidation of Organic Pollutants

    Författare :Enrique Terrazas; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biotechnology; Biokemisk teknik; Organic pollutants.; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp; Biochemical technology; Laccase; Lignin peroxidase; Manganese peroxidase; Fusarium sp. strain BOL35; Biodegradation; Bjerkandera sp. strain BOL13; Bioteknik;

    Sammanfattning : This work describes the degradation of nonylphenol, toxaphene, phenanthrene, benzo[a]pyrene and dyes using fungi and their redox enzymes. Two fungi, Bjerkandera sp. strain BOL13 and Fusarium sp. strain BOL35 were isolated from different geographic area in Bolivia. LÄS MER

  7. 5. Algal-Bacterial Photobioreactors for the Degradation of Toxic Organic Pollutants

    Författare :Raul Munoz; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioteknik; Biotechnology; symbiosis.; nutrient removal; heavy metals removal; Algal-bacterial systems photobioreactors; toxic organic pollutants;

    Sammanfattning : The aerobic biodegradation of toxic organic volatile contaminants is always limited by the low aqueous solubility of O2. Therefore, intensive bubbling or surface aeration is required to supply the bacterial community with sufficient O2 to carry out pollutant mineralization. This can cause the hazardous volatilization of toxic volatile contaminants. LÄS MER
