  1. 1. Cyanobacterial Hydrogen Metabolism : Transcriptional Regulation of the Hydrogenases in Filamentous Strains

    Författare :Rikard Axelsson; Peter Lindblad; Tomás Ruiz-Argüeso; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; Molekylärbiologi; Molecular biology; Molekylärbiologi;

    Sammanfattning : Cyanobacteria are a heterogeneous group of phototrophic microorganisms. Many cyanobacteria have the capacity to fix atmospheric nitrogen. During the process of nitrogen fixation, molecular hydrogen is produced. Three enzymes are directly involved in hydrogen metabolism in cyanobacteria. LÄS MER

  3. 2. Cyanobacterial Hydrogen Metabolism : Regulation and Maturation of Hydrogenases

    Författare :Ellenor Devine; Peter Lindblad; Karin Stensjö; Laurent Cournac; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; cyanobacteria; hydrogenase; hydrogenase specific protease; maturation; regulation; transcriptional studies; hupW; hoxW; hyp; NtcA; CalA; Biology; Biologi; Molecular biology; Molekylärbiologi; Microbiology; Mikrobiologi; Chemistry with specialization in Microbial Chemistry; Kemi med inriktning mot mikrobiell kemi;

    Sammanfattning : In times with elevated CO2 levels and global warming there is a need of finding alternatives to carbon based energy carriers. One such environmental friendly solution could be H2 produced by living organisms. LÄS MER

  4. 3. The Cyanobacterial Uptake Hydrogenase : Regulation, Maturation and Function

    Författare :Marie Holmqvist; Peter Lindblad; Karin Stensjö; Kornél Kovács; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biohydrogen; CalA; Cyanobacteria; Hydrogenase; Maturation; Nostoc punctiforme ATCC 29133; Nostoc sp. PCC 7120; Transcriptional regulation; Molecular biology; Molekylärbiologi; Molecular biology; Molekylärbiologi; Chemistry with specialization in Microbial Chemistry; Kemi med inriktning mot mikrobiell kemi;

    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

  5. 4. 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. 5. Engineering Transcriptional Systems for Cyanobacterial Biotechnology

    Författare :Daniel Camsund; Peter Lindblad; Brian Pfleger; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cyanobacteria; Synthetic biology; promoters; transcription; LacI; Gal4; Light-regulation; Chemistry with specialization in Microbial Chemistry; Kemi med inriktning mot mikrobiell kemi;

    Sammanfattning : Cyanobacteria are solar-powered cell factories that can be engineered to supply us with renewable fuels and chemicals. To do so robust and well-working biological parts and tools are necessary. LÄS MER
