  2. 1. Volatile metabolites from microorganisms in indoor environments : sampling, analysis and identification

    Author : Anna-Lena Sunesson; Alvin Fox; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Adsorbents; Analysis; Cultivation; Determination; Gas chromatography; Identification; Indicator substances; Indoor air; Mass spectrometry; Metabolites; Microbial volatile organic compounds; Optimization; Sampling; Sick buildings; Thermal desorption; Aspergillus versicolor; Cladosporium cladosporioides; Paecilomyces variotii; Pénicillium commune; Phialophora fastigiata; Streptomyces albidoflavus;

    Abstract : Microorganisms are able to produce a wide variety of volatile organic compounds. This thesis deals with sampling, analysis and identification of such compounds, produced by microorganisms commonly found in buildings. READ MORE

  4. 2. Microbial communities in biological electrochemical systems

    Author : Marie Abadikhah; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; viruses; microbial ecology. microbial electrolysis cells; bioelectrochemical system; biocathode; bioanode; microbial community assembly;

    Abstract : Biological electrochemical systems (BES) can be used as biosensors and for recovery of resources from waste streams. BES utilizes microbial communities that grow on the surface of electrodes in the form of biofilms. READ MORE

  5. 3. Metaproteogenomics-guided enzyme discovery : Targeted identification of novel proteases in microbial communities

    Author : Mikaela Johansson; Martin Karlsson; Bengt-Harald Jonsson; Florian-Alexander Herbst; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Industrial biotechnology is a large and growing industry as it is part of establishing a “greener” and more sustainable bioeconomy-based society. Using enzymes as biocatalysts is a viable alternative to chemicals and energy intense industrial processes and is en route to a more sustainable industry. READ MORE

  6. 4. Method development and applications of Pyrosequencing technology

    Author : Baback Gharizadeh; KTH; []
    Keywords : apyrase; bacterial identification; dATP?S; EST sequencing; fungal identification; human papillomavirus HPV ; microbial and viral typing; multiple sequencing primer method; Pyrosequencing technology; Sequenase; single-stranded DNA-binding protein SS;

    Abstract : The ability to determine nucleic acid sequences is one ofthe most important platforms for the detailed study ofbiological systems. Pyrosequencing technology is a relativelynovel DNA sequencing technique with multifaceted uniquecharacteristics, adjustable to different strategies, formatsand instrumentations. READ MORE

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

    Author : Anna-Sara Claeson; Anna-Lena Sunesson; Jan-Olof Levin; Steven Nordin; Bengt Järvholm; Charles Weschler; Umeå universitet; []
    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 to moisture 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.
