1. Regulation of the Cyanobacterial Bidirectional Hydrogenase
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
2. Development of robust cyanobacterial strains for biotechnological applications : Stress tolerance and cell-specific expression in heterocyst-forming cyanobacteria
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
3. Hydrogenases in the Cyanobacterium Nostoc sp. Strain PCC 73102
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
4. Characterization of the DNA-Binding Properties of the Cyanobacterial Transcription Factor NtcA
Sammanfattning : Nitrogen is an essential building block of proteins and nucleic acids and, therefore, crucial for the biosphere. Nearly 79 % of the air consists of nitrogen, but in the form of nitrogen gas (N2), which cannot be utilized by most organisms. LÄS MER
5. Cyanobacterial Hydrogen Metabolism : Transcriptional Regulation of the Hydrogenases in Filamentous Strains
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
