  3. 27. Diversity and persistence of Helicobacter pylori

    Författare :Annelie Lundin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Helicobacter pylori; genomic diversity; cag pathogenicity island; Nudix hydrolase;

    Sammanfattning : Helicobacter pylori is an exceptionally diverse bacterial species, and every infected individual harbors a unique strain, apart from the strain concordance found in some families. The infection is usually acquired during childhood and once established, persists for life unless treated with antibiotics. LÄS MER

  4. 28. Exploring Anaerobic Bacteria for Industrial Biotechnology - Diversity Studies, Screening and Biorefinery Applications

    Författare :Rosa Aragao; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anaerobic bacteria; industrial biotechnology; biorefinery; microbial diversity; single cell entrapment; llama rumen;

    Sammanfattning : Depletion of easily accessible fossil energy resources, threat of climate change and political priority to achieve energy self-sufficiency and sustainable solutions prioritize a conscious and smart use of renewable resources to generate a bio-based economy. Bio-based compounds can replace chemicals and fuels that are now mainly produced from crude oil. LÄS MER

  5. 29. Structure and function of microbial communities in constructed wetlands - influence of environmental parameters and pesticides on denitrifying bacteria

    Författare :Susann Milenkovski; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fungicide; concentration-response curves; nosZ; nirS; nirK; bacterial activity; denitrification; bacterial community composition; herbicide; insecticide;

    Sammanfattning : This thesis addresses the interactions and relationships between natural aquatic bacterial communities, environmental parameters, anthropogenic chemicals and the denitrification pathway in the habitat of agricultural constructed wetlands. The main aim was to gain fundamental knowledge of the drivers behind the processes of the denitrification (i.e. LÄS MER

  7. 30. 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
