   Abstract : Molecular hydrogen is a potential energy carrier for the future. Nitrogen-fixing cyanobacteria are a group of photosynthetic microorganisms with the inherent ability to produce molecular hydrogen via the enzyme complex nitrogenase. This hydrogen is not released, however, but is recaptured by the bacteria using an uptake hydrogenase. READ MORE

4. 2. Characterization of the DNA-Binding Properties of the Cyanobacterial Transcription Factor NtcA
