  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.; 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

  2. 2. Microbial Biofilms in the Bioinformatics Era

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

    Author : Kemal Sanli; Göteborgs universitet.; Gothenburg University.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; metagenomics; bioinformatics software; microbial biofilms; Next Generation Sequencing; pathway analysis; periphyton; marine biofilms; FANTOM; PACFM;

    Abstract : Adverse effects of anthropogenic impact on the environment have become conspicuous in the past century and among others include the gradual increase in the global CO2 levels, the contamination of air, soil and water by toxic chemicals, and the emergence of antimicrobial resistance among pathogenic microbial species. Microorganisms partake in an extreme diversity of activities in the environment, and hence, constitute the prime candidates to be investigated in understanding of the progression and effects of the aforementioned environmental hazard scenarios.

  3. 3. Evaluation of microbial health risks associated with the reuse of source-separated humna urine

    University dissertation from Stockholm : Bioteknologi

    Author : Caroline Höglund; KTH.; [2001]
    Keywords : urine-separation; urine; wastewater systems; wastewater reuse; recycling; enteric pathogens; faecal sterols; indicator bacteria; hygiene risks; microbial persistence; microbial risk assessment; QMRA; fertiliser; crop;

    Abstract : Human excreta contain plant nutrients and have the potentialto be used as a fertiliser in agriculture. Urine contributesthe major proportion of the nutrients (N, P and K) in domesticwastewater whereas faeces contribute a smaller amount andinvolves greater health risks if reused due to the possiblepresence of enteric pathogens.

  4. 4. Upper Airway Mucosal Inflammation Proteomic Studies after Exposure to Irritants and Microbial Agents

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Louise Fornander; Linköpings universitet.; Linköpings universitet.; [2015]

    Abstract : People are, in their daily lives, exposed to a number of airborne foreign compounds that do not normally affect the body. However, depending on the nature of these compounds, dose and duration of exposure, various airway symptoms may arise. READ MORE

  5. 5. Volatile organic compounds from microorganisms identification and health effects

    University dissertation from Umeå : Folkhälsa och klinisk medicin

    Author : Anna-Sara Claeson; Umeå universitet.; [2006]
    Keywords : microorganisms; building materials; VOCs; MVOCs; amines; LC-MS MS; exposure; perceived air quality; Occupational and Environmental Medicine; arbets- och miljömedicin;

    Abstract : Damp building materials are subjected to degradation processes due tomoisture and also microbial growth, with both of these giving rise to emissions of volatile organic compounds (VOCs) that may contribute to indoor air health problems. The overall aim of this thesis was to investigate emissions of reactive and non-reactive VOCs from damp building materials and from the microorganisms growing on them, and also to investigate the possible health impact of these compounds.
