  2. 1. Exploring the diversity and evolution of giant viruses in deep sea sediments using genome-resolved metagenomics

    Author : Disa Bäckström; Thijs J. G. Ettema; Anna J. Szekely; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Metagenomics; binning; viruses; NCLDV; Megavirales; viral evolution.;

    Abstract : Viruses are the most abundant biological entities on this planet, which is impressive considering that they are completely dependent on their hosts for reproduction. Recently the idea of what viruses are has changed dramatically, with the discovery of giant viruses that belong to the Nucleocytoplasmic Large DNA Viruses (NCLDV), such as Mimiviridae, Marseilleviridae, and the proposed families Pandoraviruses, and Pithoviruses.

    Abstract : 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. READ MORE

  5. 3. Investigations of the microbial diversity and dynamics in activated sludge using molecular methods

    Author : Johan Fredriksson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wastewater treatment; 16S rRNA; population dynamics; terminal restriction fragment length polymorphism; microbial ecology; Archaea; activated sludge; Bacteria;

    Abstract : Wastewater treatment is necessary to reduce the health risks and environmental impacts associated with discharge of untreated wastewater. The most common way to treat wastewater in wastewater treatment plants is through the activated sludge process. READ MORE

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

    Author : Petter Thureborn; Sara Sjöling; Mats Grahn; Matthias Labrenz; Södertörns högskola; []
    Keywords : 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;

    Abstract : 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. READ MORE

  7. 5. High-throughput DNA Sequencingin Microbial Ecology : Methods and Applications

    Author : Luisa Hugerth; Anders Andersson; Jeroen Raes; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Microbial ecology; Baltic Sea; Next-generation sequencing; Amplicon sequencing; Metagenomics; Bioteknologi; Biotechnology;

    Abstract : Microorganisms play central roles in planet Earth’s geochemical cycles, in food production, and in health and disease of humans and livestock. In spite of this, most microbial life forms remain unknown and unnamed, their ecological importance and potential technological applications beyond the realm of speculation. READ MORE
