TLDR
Blue-green algae are presumably of limited value in projects of solar energy conversion to form molecular hydrogen, because H2-formation by intact cells is found to be catalyzed exclusively by nitrogenase, and the enzyme is characterized with respect to its specifity towards electron donors and acceptors.About:

Hydrogen production by biological processes: a survey of literature
Debabrata Das,Debabrata Das +1 more
TL;DR: The paper presents a survey of biological hydrogen production processes, and the microorganisms and biochemical pathways involved in hydrogen generation processes are presented in some detail.
Journal ArticleDOI
Occurrence, classification, and biological function of hydrogenases: an overview.
Journal ArticleDOI
Classification and phylogeny of hydrogenases.
TL;DR: Compelling evidence from sequences and structures indicates that the [NiFe]- and [Fe]-H2ases are phylogenetically distinct classes of proteins, which would be consistent with the phylogenetic distinctiveness of the two classes of H2ases.

Microbial production of hydrogen : an overview
R. Nandi,S. Sengupta +1 more
TL;DR: The fate of H2 biotechnology is presumed to be dictated by the stock of fossil fuel and state of pollution in future.
Journal ArticleDOI
Nitrogen Fixation and Hydrogen Metabolism in Cyanobacteria
TL;DR: A likely better strategy is to exploit the use of radiant solar energy by the photosynthetic electron transport system to enhance the rates of H2 formation and so improve the chances of utilizing cyanobacteria as a source for the generation of clean energy.

H2 metabolism in the photosynthetic bacterium Rhodopseudomonas capsulata: H2 production by growing cultures.
P Hillmer,H Gest +1 more
TL;DR: It appears that even when light intensity is limiting, a significant fraction of the available reducing power and adenosine 5'-triphosphate is diverted to nitrogenase, resulting in H2 formation and a bioenergetic burden to the cell.

Biological formation of molecular hydrogen.
Clarke T. Gray,Howard Gest +1 more
TL;DR: It is assumed that the original pattern of reactions leading to H2 production has become modified in various ways during the course of biochemical evolution, and this point of view suggests profitable approaches for clarifying a number of problems in the intermediary metabolism of microorganisms which produce or utilize H2.

TL;DR: The hydrogenase found in Rhizobium bacteroids is compared with that found in Azotobacter and found, in all respects examined, to be similar.

Hydrogen Evolution by Nitrogen-Fixing Anabaena cylindrica Cultures.
John R. Benemann,N. M. Weare +1 more
TL;DR: Hydrogen evolution was strongly inhibited by N2 but only slightly by CO or O2, characteristics of the nitrogenase reaction in the heterocysts of Anabaena cylindrica suggest that this reaction has potential use in solar energy conversion.
