This review summarizes recent aspects of (di) nitrogen fixation and (di) hydrogen
metabolism, with emphasis on cyanobacteria. These organisms possess several types of the …

The review sums up recent data on the key enzymes involved in hydrogen evolution.
Hydrogen release by cyanobacteria is due to the effects of nitrogenases and hydrogenases …

With the global attention and research now being focussed on looking for an alternative to
fossil fuel, hydrogen is the hope of future. Cyanobacteria are highly promising …

In discussions about alternatives to our current fossil energy sources, basic and applied
research leading to biological production of molecular hydrogen utilizing cyanobacteria …

Cyanobacteria may possess several enzymes that are directly involved in dihydrogen
metabolism: nitrogenase (s) catalyzing the production of hydrogen concomitantly with the …

Nine strains of unicellular non-nitrogen-fixing cyanobacteria had high rates of hydrogen
evolution and uptake compared with filamentous nitrogen-fixing strains. Maximal hydrogen …

Cyanobacteria is a remarkable group of prokaryotic photosynthetic microorganisms, with
several genera capable of fixing atmospheric nitrogen (N2) and presenting a wide range of …

Cyanobacteria (blue-green algae) are the largest and most diverse group of photosynthetic
prokaryotes. The group encompasses wide differences in morphology, physiology and …

Several unicellular and filamentous, nitrogen-fixing and non-nitrogen-fixing cyanobacterial
strains have been investigated on the molecular and the physiological level in order to find …

As far as nitrogenase-mediated hydrogen formation is concerned, cultures of A. cylindrica
B629 showed an increasing dependence on CO 2 in the incubation for sustained H 2 …
