    Sammanfattning : Many cyanobacteria are capable of fixing atmospheric N2, a reaction that is also producing H2. This hydrogen is often metabolized by an enzyme called hydrogenase. The aim of the present work was to identify and characterize hydrogen metabolism/hydrogenases in the free-living N2-fixing cyanobacterium Nostoc sp.strain PCC 73102. LÄS MER

  5. 14. Maturation and Regulation of Cyanobacterial Hydrogenases

    Författare :Åsa Agervald; Peter Lindblad; Karin Stensjö; Ann Magnuson; Poul Erik Jensen; Uppsala universitet; []
    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

  7. 15. The Cyanobacterial Uptake Hydrogenase : Regulation, Maturation and Function

    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
