  1. 1. The aquatic microbial food web and occurence of predation-resistant and potentially pathogenic bacteria, such as Francisella tularensis

    Författare :Johanna Thelaus; Agneta Andersson; Mats Forsman; Farooq Azam; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; bacteria; protozoa; ecology; predation; nutrient-availability; microbial food web; model; predation-resistance; Francisella; reservoir; biofilm formation; Freshwater ecology; Limnisk ekologi;

    Sammanfattning : All natural aquatic systems harbour a vast variety of microorganisms. In the aquatic microbial food web, the larger microorganisms (i.e. protozoa) feed on the smaller microorganisms (i. LÄS MER

  2. 2. Dynamic Organization of Molecular Machines in Bacteria

    Författare :Bhupender Singh; Santanu Dasgupta; Leif A. Kirsebom; Don G. Ennis; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; molecular machines; bacteria; cell cycle; ribosome; replisome; divisome; spore; E. coli; H. pylori; Mycobacteria; Microbiology; Mikrobiologi; Mikrobiologi; Microbiology;

    Sammanfattning : Bacterial cells were once treated as membrane-enclosed bags of cytoplasm: a homogeneous, undifferentiated suspension in which polymers (proteins, nucleic acids, etc.) and small molecules diffused freely to interact with each other. LÄS MER

  3. 3. Environmental filtering of bacteria in low productivity habitats

    Författare :Inga Richert; Stefan Bertilsson; Annelie Wendeberg; Lise Øvreås; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; bacteria; environmental filtering; diversity; ecosystem service; hydrocarbon utilization; Southern Ocean; sediment; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology;

    Sammanfattning : Microbes fulfill important ecosystem functions by contributing as drivers of global nutrient cycles. Their distribution patterns are mainly controlled by environmental heterogeneities. So far, little is known about the mode of action of particular environmental drivers on the microbiota, particularly in low productivity habitats. LÄS MER

  4. 4. Exploring gene expression responses of marine bacteria to environmental factors

    Författare :Christofer Osbeck; Jarone Pinhassi; Michael Cunliffe; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; dissolved organic matter; model bacteria; ocean acidification; organic pollutants; river loadings; transcriptomics; Mikrobiologi; Microbiology;

    Sammanfattning : Bacterioplankton are abundant in marine ecosystems, where they as “masters of transformation” of dissolved organic matter (DOM) are important for energy fluxes and biogeochemical cycles. However, the performance of bacteria in a changing marine environment influenced by anthropogenic activities is poorly understood. LÄS MER

  5. 5. Towards time-resolved molecular interaction assays in living bacteria

    Författare :João Crispim Encarnação; Karl Andersson; Marika Nestor; U. Helena Danielson; Hélène Munier-Lehmann; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Intracellular Molecular Interactions; Real-Time Cell Binding Assays; Bacteria; LigandTracer; Kinetics; Biokemi; Biochemistry; Biofarmaci; Biopharmaceutics; Medicinsk vetenskap; Medical Science;

    Sammanfattning : Rare and neglected diseases such as multidrug resistant (MDR) tuberculosis, malaria and trypanosomiasis are re-emerging in Europe. New strategies are needed to accelerate drug discovery to fight these pathogens. LÄS MER
