  1. 1. Bacterial identification by the 16S rRNA gene

    Författare :Tobias Olofsson; Avdelningen för medicinsk mikrobiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Livsmedelsteknik; Food and drink technology; Naturvetenskap; Natural science; mykologi; virologi; Mikrobiologi; mycology; virology; bacteriology; 16S rRNA; Microbiology; Identification; Bacteria; bakteriologi;

    Sammanfattning : The identification and classification of bacteria was initially performed with morphological methods applied on cultivated bacteria. It was not until the mid 1970s, when sequences of ribosomal RNA were discovered to be useful for bacterial evolution, that a new era started. This method showed to be far more accurate for bacterial identification. LÄS MER

  3. 2. Ecology and evolution of coastal Baltic Sea 'dead zone' sediments

    Författare :Elias Broman; Mark Dopson; Nils Risgaard-Petersen; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; sediment; oxygen; metatranscriptomics; metagenomics; 16S rRNA gene; RNA-seq; dead zone; re-oxygenation; Akvatisk ekologi; Aquatic Ecology;

    Sammanfattning : Since industrialization and the release of agricultural fertilizers began, coastal and open waters of the Baltic Sea have been loaded with nutrients. This has increased the growth of algal blooms and because a portion of the algal organic matter sinks to the sea floor, hypoxia has increased. LÄS MER

  4. 3. The Baltic Sea from the present to future : microbial carbon & nutrient cycling in a changing climate

    Författare :Laura Seidel; Mark Dopson; Jarone Pinhassi; Ashfaq Ali; Stefan Hulth; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Climate change; coastal sediments; Baltic Sea; eutrophication; bacterial communities; 16S rRNA; metatranscriptomics; geochemical layers; diversity; nutrient- energy cycling; Klimawandel; Küstensediment; Ostsee; Eutrophierung; Bakterielle Gemeinschaften; 16S rRNA.; Metatranskriptome; Geochemische Schichten; Diversität; Nährstoff- Energiezyklus.; Klimatförändringar; bottensediment; kust; Östersjön; eutrofiering; mikrobiella samhällen; 16S rRNA; metatranskriptomik; geokemiska lager; diversitet; närsalts- och energiflöden; Akvatisk ekologi; Aquatic Ecology; Miljövetenskap; Environmental Science;

    Sammanfattning : Climate Change is caused by the accelerated increase of anthropogenic greenhousegas emissions to the atmosphere and affects all ecosystems on our planet. A resultof higher CO2 uptake by the oceans as well as an increase of heat trapped in theatmosphere leads to, for example acidification, stratification, sea-level rise, oxygenloss, and temperature increase of the earth’s waterbodies.

  5. 4. Towards spatial host-microbiome profiling

    Författare :Britta Lötstedt; Joakim Lundeberg; Petri Auvinen; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; 16S sequencing; RNA sequencing; spatially resolved transcriptomics; antibody-based measurements; Bioteknologi; Biotechnology;

    Sammanfattning : Sequencing technologies and applications have pushed the limits and enabled novel studies of biological mechanisms, evolutionary relationships and communication networks between cells. The technical developments leading to single cell RNA-sequencing have enabled detection of rare cell populations while spatial resolution added insights into larger biological environments, like tissues and organs.

  7. 5. Studies on the functional interaction of translation initiation factor IF1 with ribosomal RNA

    Författare :Jaroslav Belotserkovsky; Leif Isaksson; Diarmaid Hughes; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Escherichia coli; ribosome; rRNA mutation; molekylärgenetik; Molecular Genetics;

    Sammanfattning : Translation initiation factor IF1 is a small, essential and ubiquitous protein factor encoded by a single infA gene in bacteria. Although several important functions have been attributed to IF1, the precise reason for its indispensability is yet to be defined. LÄS MER
