    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; steam pretreatment; dry digestion; biogas; biohydrogen; Caldicellulosiruptor saccharolyticus; cadmium; anaerobic digestion;

    Sammanfattning : Popular Abstract in English Peter is a part-time cocoa farmer who produces cocoa beans that are used for chocolate production. However, he has always wondered about the efficient utilisation of the residual cocoa pods, which seem to contain sugar as they attract bees. LÄS MER

  2. 2. Hydrogen Production by Caldicellulosiruptor species: The Organism and the Metabolism

    Detta är en avhandling från Printed in Sweden by Media-Tryck, Lund University

    Författare :Ahmad Zeidan; Lunds universitet.; Lund University.; [2011]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Extreme thermophile; Caldicellulosiruptor; Biohydrogen; Co-culture; Coexistence; Hydrogen tolerance; Genome-scale reconstruction; In silico; Flux balance analysis;

    Sammanfattning : Popular Abstract in Swedish Hydrogen holds a great promise as an efficient and clean future energy carrier due to its high energy density and lack of pollutant generation. Anaerobic degradation of organic substrates by heterotrophic microorganisms enables the production of hydrogen from a wide spectrum of agricultural feedstock and waste products. LÄS MER

  3. 3. Physiology of Caldicellulosiruptor saccharolyticus: a hydrogen cell factory

    Detta är en avhandling från Applied Microbiology (LTH)

    Författare :Karin Willquist; Lunds universitet.; Lund University.; [2010]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; growth activation; hydrogen tolerance; hydrogen yields CO2 inhibition; physiology; enzyme kinetics; Caldicellulosiruptor saccharolyticus; biohydrogen; energy metabolism;

    Sammanfattning : Popular Abstract in Swedish Biovätgas är en mycket energirik och förnyelsebar energikälla för bilar och elproduktion som genererar mycket lite av växthusgasen koldioxid. Vätgasen kan framställas av billiga råvaror såsom hushållsavfall, industriellt avfall och av lignocellulosa. LÄS MER

  4. 4. Maturation and Regulation of Cyanobacterial Hydrogenases

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Åsa Agervald; Uppsala universitet.; [2009]
    Nyckelord :Biohydrogen; Cyanobacteria; Nostoc sp. PCC 7120; Nostoc punctiforme PCC 73102; Hydrogenase; Maturation; Transcriptional regulation; CyAbrB; CalA; FeSOD;

    Sammanfattning : Accelerated global warming plus an increasing need for energy is an equation not easily solved, thus new forms of sustainable energy production are urgently requested. In this context hydrogen production based on a cyanobacterial system offers an environmentally friendly alternative for energy capture and conversion. LÄS MER

  5. 5. The Cyanobacterial Uptake Hydrogenase Regulation, Maturation and Function

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Marie Holmqvist; Uppsala universitet.; [2010]

    Sammanfattning : With accellerating global warming and pollution problems a change of energy regime is necessary. Solar energy offers a clean and unlimited energy source of enormous potential. Due to it’s intermittenet nature solar energy must be stored - ideally in the chemical bond of a carrier molecule. LÄS MER
