  1. 1. Bacterioplankton in the light of seasonality and environmental drivers

    Författare :Carina Bunse; Jarone Pinhassi; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; marine bacteria; marine microbiology; seasonal succession; ocean acidification; proteorhodopsin; photoheterotrophy; microbial time series; Akvatisk ekologi; Aquatic Ecology; Mikrobiologi; Microbiology; Miljövetenskap; Environmental Science;

    Sammanfattning : Bacterioplankton are keystone organisms in marine ecosystems. They are important for element cycles, by transforming dissolved organic carbon and other nutrients. Bacterioplankton community composition and productivity rates change in surface waters over spatial and temporal scales. LÄS MER

  3. 2. Microbial risk assessment and its implications for risk management in urban water systems

    Författare :Therese Westrell; Thor-Axel Stenström; Nick Ashbolt; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Quantitative microbial risk assessment; pathogens; urban; decentralised; failures; noroviruses; water consumption; HACCP; drinking water; wastewater; sludge; faeces; risk management; Water in nature and society; Vatten i natur och samhälle;

    Sammanfattning : Infectious disease can be transmitted via various environmental pathways, many of which are incorporated into our water and wastewater systems. Quantitative microbial risk assessment (QMRA) can be a valuable tool in identifying hazard exposure pathways and estimating their associated health impacts. LÄS MER

  4. 3. Real-time PCR for diagnosis of botulism and quantification of neurotoxin gene expression in Clostridium botulinum

    Författare :Ingrid Artin; Avdelningen för medicinsk mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; detection; qRT-PCR; Clostridium botulinum; molecular methods;

    Sammanfattning : The objectives of the work presented in this thesis have been to develop molecular methods for (i) detection of Clostridium botulinum in food and clinical samples, and (ii) monitoring the expression of the neurotoxin gene, cnt, during different growth phases and under different growth conditions. For the diagnosis of botulism, a real-time PCR-based method including an internal amplification control for C. LÄS MER

  5. 4. Treatment of Textile Wastewater by Combining Biological Processes and Advanced Oxidation

    Författare :Marisa Punzi; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Azo dye; textile wastewater; biological treatment; biofilm; microbial community; DGGE; green algae; photo-Fenton; ozone; toxicity; mutagenicity; LCA; cost analysis;

    Sammanfattning : Treatment of textile wastewater is challenging because the water contains toxic compounds that have low biodegradability. Dyes, detergents, surfactants, biocides and more are used to improve the textile process and to make the clothes resistant to physical, chemical and biological agents. LÄS MER

  7. 5. The influence of soil structure on microbial processes in microfluidic models

    Författare :Carlos Arellano; MEMEG; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The way microbes behave in nature can vary widely depending on the spatial characteristics of the habitats they are located in. The spatial structure of the microbial environment can determine whether and to which extent processes such as organic matter degradation, and synergistic or antagonistic microbial processes occur.
