  1. 16. Regulation of the Cyanobacterial Bidirectional Hydrogenase

    Författare :Paulo Oliveira; Peter Lindblad; Aaron Kaplan; Uppsala universitet; []
    Nyckelord :Biology; Biohydrogen; Cyanobacteria; Synechocystis; Anabaena Nostoc; Bidirectional hydrogenase; Transcription regulation; LexA; AbrB-like protein; Biologi;

    Sammanfattning : Today, mankind faces a new challenge in energetic terms: a new Industrial Revolution is imperative, already called by some as an Energetic Revolution. This corresponds to a conversion to clean, environmentally friendly and renewable energy sources. LÄS MER

  3. 17. Specificity in natural and artificial cyanobacterial symbioses

    Författare :Malin Nilsson; Kristina Lindström; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plant physiology; Växtfysiologi; växtfysiologi; Plant Physiology;

    Sammanfattning : Cyanobacteria, primarily of the genus Nostoc, form symbioses with a wide variety of plants. The diversity of cyanobacterial strains in these symbioses, and the specificity of interaction, vary greatly. A high diversity at the strain level has been suggested for bryophytes and cycads, whereas a low diversity is found in lichens. LÄS MER

  4. 18. The tRNALeu (UAA) Intron of Cyanobacteria : Towards Understanding a Genetic Marker

    Författare :José Luis Costa; Peter Lindblad; Paulsrud Per; Sandra Nierzwicki-Bauer; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; Biologi; Biology; Biologi;

    Sammanfattning : The tRNALeu (UAA) intron has been recorded in the plastid genome of many algae and land plants and was the first intron to be discovered in cyanobacteria. In all known cases it interrupts the tRNALeu anticodon loop at a conserved position (U-intron-AA). LÄS MER

  5. 19. The novel sources of the neurotoxin BMAA in aquatic environments

    Författare :Sandra Lage; Sara Jonasson Rydberg; Ulla Rasmussen; Ann-Sofi Rehnstam-Holm; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; β-N-methylamino-L-alanine; diatoms; dinoflagellates; shellfish; cockles; PST; växtfysiologi; Plant Physiology;

    Sammanfattning : Neurotoxinet β -N-metylamino -L-alanin (BMAA) anses vara en potentiell miljöriskfaktor för utvecklingen av den neurodegenerativa sjukdomen amyotrofisk lateralskleros (ALS) och har en potentiell roll i flertalet andra neurodegenerativa sjukdomar. Sedan 2003, då det upptäcktes att BMAA produceras av den symbiotiska cyanobakterien Nostoc punctiforme  har flera andra BMAA producerande cyanobakteriearter identifierats. LÄS MER

  7. 20. Expression and synthetic activation of [FeFe]-hydrogenases in cyanobacteria

    Författare :Adam Wegelius; Peter Lindblad; Karin Stensjö; Namita Khanna; Matthew Posewitz; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry with specialization in Microbial Chemistry; Kemi med inriktning mot mikrobiell kemi;

    Sammanfattning : Photosynthetic microbes can be utilized for hydrogen production, generating a clean, carbon neutral energy carrier from abundant substrates. Cyanobacteria are photosynthetic prokaryotes with large potential for biotechnological energy applications and several strains are capable of hydrogen production. LÄS MER
