  2. 1. F F₁-ATPase of plant mitochondria : purification and characterization of the structural and functional properties of the individual subunits

    Author : Beston Hamasur; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Plant leaf cells constitute a unique system in which both mitochondria and chloroplasts are responsible for energy conversion. In both organelles, ATP synthase is responsible for the synthesis of ATP from ADP and Pi in a process coupled to an electron transfer chain. READ MORE

  4. 2. Phytoremediation of soil contaminated with petroleum hydrocarbons and trace elements

    Author : Charlotte Marchand; Hogland William; Hijri Mohamed; Bramryd Torleif; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Petroleum Hydrocarbon; Trace Elements; Gentle Soil Remediation Options; Polycyclic Aromatic Hydrocarbon; Respirometry; Ecopile; Bacteria; Fungi; Miljövetenskap; Environmental Science;

    Abstract : The rapid urbanization and industrialization has led to an increase of disposal petroleum hydrocarbons (PHC) and trace elements (TE) into the environment. These pollutants are considered as the most toxic contaminants in the world due to their persistence in the environment, and the long range of toxicological effects for living beings. READ MORE

  5. 3. Denitrification as an adaptive trait in soil and groundwater bacteria

    Author : Christer Bergwall; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; microcosm; forest soil; aquifer; groundwater; reductase; nitrous oxide; nitric oxide; nitrite; nitrate; selection; adaptation; bacteria; nitrification; Denitrification; dissimilatory nitrate reduction to ammonium; fertiliser; 15NO3-; 15NH4 ; Ecology; Ekologi;

    Abstract : The focus of the thesis is on selection and adaptation processes in bacteria with emphasis on denitrifying bacteria in groundwater. Other nitrogen transformation processes such as dissimilatory nitrate reduction to ammonium (nitrate ammonification) and nitrification of forest soil bacteria are briefly discussed. READ MORE

  6. 4. Diagnosis of urinary tract infections : aspects of quality assurance and communication of concepts

    Author : Olle Aspevall; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Accreditation; concept system; chromogenic culture medium; external quality assessment; microbiology; terminology; urine culture.;

    Abstract : Urinary tract infection (UTI) is a common disease; most cases are managed in primary health care (PHC. Dipslide (a type of urine culture test designed for point of care testing) is used in PHC in Sweden for the diagnosis of UTI. The results in an external quality assessment programme initiated in 1993 for dipslide did not improve over the years. READ MORE

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

    Author : Sigurlaug Skirnisdottir; Bioteknik; []
    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
