  1. 1. Soil salinity as a driver of microbial community structure and functioning

    University dissertation from Lund University, Faculty of Science, Centre for Environmental and Climate Research (CEC)

    Author : Kristin Rath; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [2017-12]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Soil salinization; Soil Microbiology; soil microbial community; Bacteria; Aerobic; Fungi; Drying-rewetting; Microbial growth; Microbial biomass; Soil respiration; salinity tolerance; Saline soils; Salinity gradient;

    Abstract : High concentrations of salts in agricultural soils are an environmental problem that has plagued human civilization from its very beginning. Already the earliest civilizations in ancient Mesopotamia struggled with increasing concentrations of salt on irrigated fields. READ MORE

  3. 3. Microbial Community Assembly during Aerobic Granulation

    University dissertation from Chalmers University of Technology

    Author : Raquel Liebana; Chalmers tekniska högskola.; Chalmers University of Technology.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; membrane bioreactors; aerobic granular sludge; reproducibility; sequencing batch reactors; washout dynamics; fluorescence in-situ hybridization; granulation; microbial community dynamics;

    Abstract : Environmental deterioration together with the increasingly restrictive legislation of water quality standards have led to a demand for compact, efficient and less energy consuming technologies for wastewater treatment. Aerobic granular membrane bioreactors (AGMBRs) combine the advantages of aerobic granular sludge and membrane filtration. READ MORE

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

    University dissertation from Huddinge : Södertörns högskola

    Author : Petter Thureborn; Södertörns högskola.; [2016]
    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
