Photoproduction of hydrogen by photosystem I of Scenedesmus

  title={Photoproduction of hydrogen by photosystem I of Scenedesmus},
  author={Tim S. Stuart and Heinrich Kaltwasser},
Anaerobically adapted and illuminated Scenedesmus evolves molecular hydrogen from endogenous organic compounds. This photoproduction of H2 does not require photosystem II, since 5x10-6 M DCMU, which inhibited normal photosynthesis almost completely, did not significantly inhibit the photoevolution of H2. The relative efficiencies in far-red light of photosynthesis, photoreduction and H2 production were determined. Photohydrogen evolution was comparatively the most efficient of these three… CONTINUE READING
