  1. 11. Recruitment from resting stages among bloom-forming cyanobacteria

    Författare :Annika Ståhl-Delbanco; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; aquatic ecology; limnology; Marinbiologi; limnologi; akvatisk ekologi; marine biology; Hydrobiology; resting stage; Cyanobacteria; recruitment; algal bloom;

    Sammanfattning : Cyanobacteria are known to form heavy blooms in eutrophicated freshwaters and also form resting stages, associated with the sediments, during harsh growth conditions. These resting stages can serve as inoculum for pelagic populations and function as a potential source for bloom formations. LÄS MER

  3. 12. Metabolic engineering strategies to increase n-butanol production from cyanobacteria

    Författare :Josefine Anfelt; Elton P. Hudson; Mathias Uhlén; Patrik R. Jones; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cyanobacteria; metabolic engineering; biofuels; butanol; synthetic scaffold; CRISPRi; solvent tolerance; Bioteknologi; Biotechnology;

    Sammanfattning : The development of sustainable replacements for fossil fuels has been spurred by concerns over global warming effects. Biofuels are typically produced through fermentation of edible crops, or forest or agricultural residues requiring cost-intensive pretreatment. LÄS MER

  4. 13. Development of robust cyanobacterial strains for biotechnological applications : Stress tolerance and cell-specific expression in heterocyst-forming cyanobacteria

    Författare :Xin Li; Karin Stensjö; Yagut Allahverdiyeva-Rinne; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cyanobacteria; Dps protein; heterocysts; Nostoc; oxidative stress; cell specific promoter; ROS tolerance; synthetic biology tools transcriptional regulation.; Biokemi; Biochemistry;

    Sammanfattning : Synthetic biology tools can be used to exploit potential applications of cyanobacteria, promising photosynthetic hosts for production of fuels and chemicals. Specific genetic tools are needed for the development of robust cyanobacterial strains for bioengineering. LÄS MER

  5. 14. Effects and Dynamics of Insertion Sequences in the Evolution of Cyanobacteria

    Författare :Carl Theoden Vigil Stenman; Birgitta Bergman; Andersson Siv; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cyanobacteria; Insertion Sequences; Evolution; Plant Physiology; växtfysiologi;

    Sammanfattning : Cyanobacteria are globally widespread and ecologically highly significant photoautotrophic microorganisms, with diverse geno- and phenotypic characters unprecedented among prokaryotes. This phylum embraces representatives with an exclusive adaptability in highly specialized environments, from oligotrophic ocean waters to the interior of cells in symbiotic plants, the most extreme being the chloroplasts.

  7. 15. On the ecophysiology of Baltic cyanobacteria focusing on bottom-up factors

    Författare :Malin Mohlin; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Allelopathy; Aphanizomenon sp.; Baltic Sea; Cyanobacteria; Diazotrophic; Multi-factorial; Nitrogen; Nodularin; photosynthetic active radiation; Phosphorus; ultraviolet radiation; UV-A; UV-B;

    Sammanfattning : Cyanobacterial blooms in the Baltic Sea are dominated by diazotrophic cyanobacteria, i.e. Aphanizomenon sp. and Nodularia spumigena. LÄS MER
