  1. 31. Redox Regulation and Stress Responses - Studies in Bacillus subtilis

    Författare :Jonas Larsson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; redox sensor; oxygen sensor; reactive nitrogen species; RNS; Biology; Biologi; Microbiology; bacteriology; virology; mycology; bakteriologi; Mikrobiologi; virologi; mykologi; Bacillus subtilis; Rex; yjbI; ydiH; yjbH; redox regulation;

    Sammanfattning : Redox reactions are central to all organisms to sustain life. Both anabolic and catabolic metabolism depends on them. It is thus vital to sense and adjust the redox balance in the cell. One major factor affecting the redox status is the level of oxygen present. LÄS MER

  3. 32. Biobased production of succinic acid by Escherichia coli fermentation

    Författare :Christian Andersson; Gen Larsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biokemisk processteknik; Biochemical Process Engineering;

    Sammanfattning : The prospects of peak oil, climate change and the dependency of fossil carbon have urged research and development of production methods for the manufacture of fuels and chemicals from renewable resources (biomass). The present thesis illustrates different aspects of biobased succinic acid production by a metabolically engineered E. coli strain. LÄS MER

  4. 33. Inhibition of Nitrification in Municipal Wastewater - Sources, Effects, Evaluation and Remedies

    Författare :Karin Jönsson; Vattenförsörjnings- och avloppsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; Wastewater; Toxicity; Nitrification; Inhibition; pollution control; Miljöteknik; kontroll av utsläpp;

    Sammanfattning : Today, as a rule, the most cost-effective way to remove nitrogen from municipal wastewater is the biological method based on nitrification and subsequent denitrification. All biological systems may be affected by toxicants, and biological nitrogen removal is no exception. LÄS MER

  5. 34. Identification and origin of potential background carcinogens : endogenous isoprene and oxiranes, dietary acrylamide

    Författare :Eden Tareke; Rafter Joseph; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; Miljökemi; Environmental Chemistry; miljökemi;

    Sammanfattning : The primary aims of this thesis are to discover carcinogens in the general population by identification of products of reaction with hemoglobin (Hb adducts) in blood from humans without known exposure, and tracing the origin of the adducts. Chemicals and/or their metabolites forming Hb adducts mostly also react with DNA and may thus cause mutations, a key event in carcinogenesis. LÄS MER

  7. 35. Structure-function studies of epoxide hydrolases

    Författare :Agata Naworyta; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Epoxides are three-membered cyclic ethers formed in cells via several metabolic pathways. Epoxide hydrolases (EHs) are enzymes that hydrolyse epoxides to the corresponding diols. The main goal of this thesis was to investigate the structures of EHs from the alpha/beta-hydrolase family. LÄS MER
