  2. 6. Ammonia-Oxidising Bacteria in Soil : Studies of diversity and abundance using 16S rRNA gene analysis

    Author : Anna Hermansson; Janet Jansson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Nitrification is the process whereby ammonia is oxidised to nitrate. The first step of this process is carried out by the chemoautotrophic, ammonia-oxidising bacteria (AOB), which convert ammonia to nitrite. READ MORE

  4. 7. Lactobacillus iners and the normal vaginal flora

    Author : Tell Jakobsson; Urban Forsum; Lars Fåhraeus; Per-Göran Larsson; Ingegerd Adlerberth; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Vagina; microbes; lactobacilli; phenotypic methods; molecular biology; 16S rRNA; pyrosequencing; Clinical bacteriology; Klinisk bakteriologi;

    Abstract : The ecological niche of the vagina contains a large number of different microbes that are constantly interacting with each other and the host. Culture methods have not been sufficient in order to resolve the complexity of the normal vaginal flora. READ MORE

  5. 8. Kleptoplasty in Dinophysis spp : Ecological role and evolutionary implications

    Author : Susanna Minnhagen; Paulo Salomon; Gregory Doucette; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dinophysis; kleptoplastid; real-time PCR; 16S rRNA; plastid evolution; Baltic Sea; Flow cytometry; Marine ecology; Marin ekologi; Akvatisk ekologi; Aquatic Ecology;

    Abstract : This thesis deals with the question of whether planktonic protits of the genus Dinophysis have permanent plastids (=chloroplasts) or practice kleptoplasty, i.e. acquire plastids via predation on other microorganisms. Sequencing the plastid 16S rDNA of Dinophysis spp. READ MORE

  6. 9. The Niches of Bacterial Populations in Productive Waters : Examples from Coastal Waters and Four Eutrophic Lakes

    Author : Alexander Eiler; Stefan Bertilsson; Lars J. Tranvik; Janet Jansson; Katherine McMahon; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecology; diversity; 16S rRNA; phytoplankton; bloom; pathogen; carbon cycle; Ekologi;

    Abstract : Recent research in microbial ecology has focused on how aquatic bacterial communities are assembled. Only a few of these studies follow a “Gleasonian” approach where the roles of single bacterial populations are in focus. READ MORE

  7. 10. Investigations of the microbial diversity and dynamics in activated sludge using molecular methods

    Author : Johan Fredriksson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wastewater treatment; 16S rRNA; population dynamics; terminal restriction fragment length polymorphism; microbial ecology; Archaea; activated sludge; Bacteria;

    Abstract : Wastewater treatment is necessary to reduce the health risks and environmental impacts associated with discharge of untreated wastewater. The most common way to treat wastewater in wastewater treatment plants is through the activated sludge process. READ MORE
