    Sammanfattning : Carbon dioxide (CO2) emissions from human activities are driving climate change, but the pending crisis could be mitigated by a circular carbon economy where released CO2 is recycled into commodity chemicals. Autotrophic microbes can make a contribution by producing chemicals, such as biofuels, from CO2 and renewable energy. LÄS MER

  4. 13. Microbial Ecosystem Functions Along the Steep Oxygen Gradient of the Landsort Deep, Baltic Sea

    Författare :Petter Thureborn; Sara Sjöling; Mats Grahn; Matthias Labrenz; Södertörns högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; microbial ecology; ecosystem functions; microbial community; bacteria; archaea; metagenomics; metatranscriptomics; oxygen gradient; hypoxia; sediment; Baltic Sea; Environmental Studies; Miljövetenskapliga studier; Östersjö- och Östeuropaforskning; Baltic and East European studies;

    Sammanfattning : Through complex metabolic interactions aquatic microbial life is essential as a driver of ecosystem functions and hence a prerequisite for sustaining plant and animal life in the sea and on Earth. Despite its ecological importance, infor­mation on the complexity of microbial functions and how these are related to environmental conditions is limited. LÄS MER

  5. 14. Evolutionary transitions across the tree of life : Phylogenomic case studies in environmental archaea, bacteria and eukaryotes

    Författare :Max Emil Schön; Thijs J. G. Ettema; Fabien Burki; David Moreira; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Evolutionary transitions; environmental sequencing; metagenomics; single-cell genomics; phylogenomics; haloarchaea; Hikarchaeia; Rickettsiales; Picozoa; plastid evolution; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Sammanfattning : Microbes form the majority of life on Earth, but have been systematically underrepresented in historical research. The sequencing revolutions of the last two decades have completely changed the way we can study microbial genomic information, giving us the means to probe ever deeper into their evolution. LÄS MER

  7. 15. Niche differentiation of ammonia oxidizing bacteria and archaea in managed soils

    Författare :Ella Wessén; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Soils offer humanity a multitude of ecosystem services, including production of food and clean drinking water, and many such services are driven by soil microbial communities. However, human activities are constantly affecting soil ecosystems through altered land use or various management strategies, and thereby influence microbial communities and their functions. LÄS MER
