  1. 1. Microbial Biofilms in the Bioinformatics Era

    Författare :Kemal Sanli; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; metagenomics; bioinformatics software; microbial biofilms; Next Generation Sequencing; pathway analysis; periphyton; marine biofilms; FANTOM; PACFM; PACFM;

    Sammanfattning : Adverse effects of anthropogenic impact on the environment have become conspicuous in the past century and among others include the gradual increase in the global CO2 levels, the contamination of air, soil and water by toxic chemicals, and the emergence of antimicrobial resistance among pathogenic microbial species. Microorganisms partake in an extreme diversity of activities in the environment, and hence, constitute the prime candidates to be investigated in understanding of the progression and effects of the aforementioned environmental hazard scenarios.

  3. 2. Acid Tolerance of Streptococcus Mutans Biofilms

    Författare :Jessica Neilands; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Acid tolerance; Streptococcus mutans; Biofilms; Acid stress; Fluoride;

    Sammanfattning : Mikrobiologisk forskning har till stor del bedrivits genom att man odlat bakterier i näringslösningar och på agarplattor och sedan studera bakterierna på olika sätt. Detta sätt att odla bakterier överensstämmer inte särskilt bra med hur bakterier växer i verkligenheten. LÄS MER

  4. 3. Microbial communities in anammox and nitrifying biofilms

    Författare :Carolina Suarez; Göteborgs universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; biofilms; AOB; partial nitritation anammox; nitrification; wastewater;

    Sammanfattning : Excess of nitrogen in water bodies causes eutrophication. One important source of nitrogen is the effluent from wastewater treatment plants (WWTPs). Nitrogen in wastewater is most commonly removed by nitrification-denitrification. LÄS MER

  5. 4. Biofilms in Nitrogen Removal - Bacterial Population Dynamics and Spatial Distribution

    Författare :Robert Almstrand; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; AOB; NOB; biofilms; image analysis; FISH; Nitrosomonas; population dynamics; spatial distribution;

    Sammanfattning : Efficient nitrogen removal at wastewater treatment plants (WWTPs) is necessary to avoid eutrophication of recipient waters. The most commonly used approach consists of aerobic nitrification and subsequent anaerobic denitrification resulting in the release of dinitrogen gas into the atmosphere. LÄS MER

  7. 5. "Under pressure" : interaction between pharmaceuticals and river bacteria

    Författare :Aleksandra Hagberg; Madeleine Ramstedt; Mette Burmølle; Jerker Fick; Rikke Louise Meyer; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biofilms; river bacteria; pharmaceutical contamination;

    Sammanfattning : Pharmaceuticals are often entering the environment without being completely decomposed. Once released in the environment they continue to carry on their main function but instead targeting the inhabitants of the aquatic ecosystem. Our interest was drawn towards the bacteria, that are often present in the environment in the form of biofilms. LÄS MER
