  2. 1. Vitreoscilla hemoglobin. In vitro mutagenesis and transcript profiling to improve its biotechnological usefulness

    Author : Charlotte Andersson; Tillämpad biokemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemical technology; Biokemisk teknik; gene expression analysis; transcript profiling; microarray; DNA chips; microaerobic; hypoxia; oxygen-limited; bacterial hemoglobin; Escherichia coli; Vitreoscilla hemoglobin VHb ;

    Abstract : Vitreoscilla is an obligate aerobic bacterium found in oxygen-poor environments such as stagnant ponds and decaying vegetable matter. Vitreoscilla induces the production of a homodimeric hemoglobin (VHb) when subjected to oxygen-limiting conditions. READ MORE

  5. 3. Analysis and Control of Continuous Microaerobic Ethanol Production by Yeast

    Author : Carl Johan Franzén; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nitrogen limitation; ethanol; Saccharomyces cerevisiae; glycerol; metabolic flux analysis; oxygen limitation; stoichiometric model; yeast physiology; RQ control;

    Abstract : Glucose fermentation by Saccharomyces cerevisiae, and xylose fermentation by Candida utilis and Pichia stipitis, were investigated under microaerobic conditions. A dynamic experimental method named oxygen programmed fermentation (OPF), and a method for microaerobic RQ control in continuous culture have been developed. READ MORE

  6. 4. Morphological changes in mycobacteria

    Author : Malavika Ramesh; Leif A. Kirsebom; Anders Løbner-Olesen; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mycobacteria; pleomorphism; dnaK_3; microaerobic condition; Morphology; oxygen deprivation; spore-like cells; Biology with specialization in Molecular Biology; Biologi med inriktning mot molekylärbiologi;

    Abstract : Morphological variations at different stages and conditions of growth has been observed frequently in various mycobacteria. Despite years of research, the molecular basis of such variations is still not clear and requires further elucidation. READ MORE

  7. 5. Fermentation of undetoxified dilute acid lignocellulose hydrolysate for fuel ethanol production

    Author : Tomas Brandberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydrolysate; lignocellulose; Saccharomyces cerevisiae; nitrogen limitation; microaerobic conditions; cell recirculation; continuous fermentation; Mucor indicus; ethanol; cell retention;

    Abstract : Important aspects of ethanol production from undetoxified dilute acid lignocellulose hydrolysate are covered in this thesis, which primarily focuses on the use of Saccharomyces cerevisiae (Baker's yeast) as the biocatalyst. Nine different strains of S. READ MORE
