title: Hydrogen metabolism in the facultative anoxygenic cyanobacteria (blue-green algae) Oscillatoria limnetica and Aphanothece halophytica.
abstract: Two facultative anoxygenic photoautotrophic cyanobacteria, Oscillatoria limnetica and Aphanothece halophytica were found capable of CO2 photoassimilation using molecular hydrogen as electron donor in a photosystem I driven reaction. A. halophytica was also capable of evolving hydrogen from Na-dithionite reduced methylviologen in a light independent reaction.
