  2. 1. Appraisal of strategies to improve thermophilic hydrogen production exploiting Caldicellulosiruptor species

    Author : Eoin Byrne; Teknisk mikrobiologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Caldicellulosiruptor; Hydrogen; osmotolerance; Biorefinery; Osmolarity; Adaptive laboratory evolution; Co-culture; Volumetric productivity; Methane; Polyhydroxybutyrate; Coprothermobacter proteolyticus;

    Abstract : The transition from a fossil to a bio-based economy is of vital importance to stem the effects of ongoing climate change.This bio-based economy will necessitate the production of both biofuels and chemical compounds from biologicalsources. READ MORE

  4. 2. Caldicellulosiruptor Saccharolyticus: an Ideal Hydrogen Producer?

    Author : Sudhanshu Pawar; Avdelningen för kemiteknik; []
    Keywords : Caldicellulosiruptor owensensis; Caldicellulosiruptor saccharolyticus; hydrogen; volumetric hydrogen productivity; biofilm; osmotolerance; wheat straw hydrolysate; evolutionary engineering; CSTR; UA reactor and uracil auxotrophy;

    Abstract : Caldicellulosiruptor saccharolyticus is an extremely thermophilic, strictly anaerobic, Gram-positive and cellulolytic microorganism with a natural ability to produce hydrogen (H2) at nearly theoretical maximum yield, i.e. 4 mol/ mol of glucose. READ MORE

  5. 3. Design of kinetic models for assessment of critical aspects in bioprocess development : A case study of biohydrogen

    Author : Johanna Björkmalm; Teknisk mikrobiologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; kinetic models; biohydrogen; Caldicellulosiruptor; substrate; diauxic; inhibition; osmotolerance;

    Abstract : The world faces major climate challenges and extensive efforts need to be taken to combat this issue. Replacing fossil-derived fuels and chemicals with renewables are one important step on the way. Hydrogen has a great potential as a renewable energy carrier for the transport sector and as a green chemical for the industry. READ MORE

  6. 4. Biotic and abiotic stress in microorganisms and plants: Some Mechanisms of Stress and Programmed Cell Death. Genetic Engineering Approaches Towards Improved Stress Tolerance

    Author : Per-Johan Meijer; Tillämpad biokemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biotic stress; plants; microorganisms; stress tolerance; antifreeze protein; proline; programmed cell death; systemic aquired resistance; Biochemistry; metabolism; Biokemi; Bioteknik; Biotechnology; abiotic stress;

    Abstract : Various forms of stress, such as biotic and abiotic stress, were studied in microorganisms and plants to learn more about the underlying mechanisms of such stress and potential genetic engineering strategies towards stress tolerance. An antifreeze protein from winter flounder, expressed in E. READ MORE

  7. 5. Development of molecular biology tools for the wine and beer yeast Dekkera bruxellensis

    Author : Anna Schifferdecker; Molekylär cellbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; non-conventional yeasts; Dekkera bruxellensis; genetic tools; chromosomes variability; glucose fermentation; genotype-phenotype paradigm; baking yeasts;

    Abstract : The non-conventional wine and beer yeast Dekkera bruxellensis is of great interest for the food industry and academic research. This Crabtree-positive yeast is a good ethanol producer and can compete the baker´s yeast Saccharomyces cerevisiae, in ethanol and pH tolerance and could be an even better organism for the biofuel production from alternative carbon sources.
