Biophotolysis in Various Bacterial and Algal Cultures - I determined which microorganisms most efficiently produce hydrogen through biophotolysis (the microbial production of hydrogen): photosynthetic bacteria from the soil or natural water, Anabaena sp. Of cyan bacteria, or Chlamydomonas Reinhardt sp. of Eukaryotic Algae. I believe the photosynthetic bacteria from the soil are the most effective hydrogen producers.

Biophotolysis of water - Method for continuous production of H2 via the biophotolysis of water in a two step process using a reversibly reduceable cofactor and synergistic photometabolically active microorganisms. The rate of H2 production can be increased utilizing transition metal ions as catalysts.

Biophotolysis-based Hydrogen Production by Cyan bacteria and Green Micro algae - Biological hydrogen evolution provides a sustainable and environmentally friendly way to produce clean energy from renewable resources. Cyanobacteria and green microalgae split water into molecular hydrogen and oxygen using sunlight under special conditions. This mini review examines the technology status of direct and indirect biophotolysis for hydrogen production. Progress has been made in solving the intrinsic incompatibility of the simultaneous evolution of hydrogen and oxygen gas in photoautotrophic cells, particularly the adverse impact on the key hydrogen enzymes (hydrogenase and nitrogenase). Technical challenges for sustained hydrogen production are outlined.
