1. 1. Atmospheric Chemistry of Volatile Organic Compounds: Oxidation Products, Mechanisms and Secondary Organic Aerosol Formation

   Författare :Julia Hammes; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SOA; VOC; anthropogenic; biogenic; FIGAERO; CIMS; HOMs; ELVOCs; atmospheric oxidation; chemical mechanism; NOx; limonene; a-pinene; TMB; ozone; nitrate; OH; radical chemistry; RO2; G-FROST; GO:PAM;

   Sammanfattning : The results from this work are a piece in understanding the complex puzzle of atmospheric aerosol formation. Secondary organic aerosol (SOA) formed by the oxidation of volatile organic compounds (VOC) in the atmosphere is a key component of air pollution with a strong negative impact on human health and influence on climate, but its formation is poorly understood.

3. 2. Nitrogen-containing products from atmospheric oxidation of volatile organic compounds

   Författare :Epameinondas Tsiligiannis; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; VOC; anthropogenic; biogenic; SOA; atmospheric oxidation; organic aerosols; CIMS; FIGAERO; TMB; isoprene; HOM; organonitrates ONs ; NOx; OH; nitrate NO3 ; Go:PAM; SAPHIR;

   Sammanfattning : Atmospheric oxidation of volatile organic compounds (VOC) produces a wide range of oxygenated organic products that lead to formation of secondary organic aerosol (SOA). SOA represents a significant fraction of the tropospheric aerosol that influence climate and human health. LÄS MER

4. 3. Toxicokinetics of inhaled trimethylbenzenes in man

   Författare :Jill Järnberg; Uppsala universitet; []
   Nyckelord :Medical sciences; trimethylbenzene; dimethylhippuric acid; white spirit; toxicokinetics; biological monitoring; human; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; arbets- och miljömedicin; Occupational and Environmental Medicine;

   Sammanfattning : In the toxicological risk assessment, data on the uptake and disposition (toxicokinetics) of the chemical is important. The three isomeric trimethylbenzenes (TMBs) are widely used as components in solvent mixtures and motor fuels. LÄS MER

5. 4. Engineering xylose and arabinose metabolism in recombinant Saccharomyces cerevisiae

   Författare :Kaisa Karhumaa; Teknisk mikrobiologi; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; virologi; bakteriologi; mycology; Mikrobiologi; bacteriology; Saccharomyces cerevisiae ; arabinose; xylose; fermentation; lignocellulose; yeast; mykologi; Biochemical technology; Biokemisk teknik; virology; Microbiology; ethanol;

   Sammanfattning : Utilization of all sugars in lignocellulose hydrolysates is a prerequisite for economically feasible bioethanol production. The yeast commonly used for industrial ethanol production, Saccharomyces cerevisiae, is naturally unable to utilize pentose sugars xylose and arabinose, which constitute a large fraction of many lignocellulosic materials.

7. 5. Metabolic engineering and random mutagenesis for improved xylose utilisation of Saccharomyces cerevisiae

   Författare :Fredrik Wahlbom; Teknisk mikrobiologi; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biokemisk teknik; Biochemical technology; mykologi; virologi; bacteriology; Microbiology; Kemiteknik och kemisk teknologi; Chemical technology and engineering; ethanol; Saccharomyces; xylose; virology; mycology; Mikrobiologi; bakteriologi;

   Sammanfattning : In this thesis I have summarised my work on the analysis and improvement of xylose utilisation by recombinant S. cerevisiae. A metabolic flux model was developed and used to analyse the intracellular fluxes in the recombinant xylose utilising S. cerevisiae TMB 3001 cultivated in chemostat at various dilution rates and xylose/glucose concentrations.
