Cyanobacteria are photoautotrophic prokaryotes with a remarkable metabolic flexibility. Many species of cyanobacteria produce hydrogen, and the efficiency of this process can be improved by genetic engineering. Isolated photosynthetic complexes of cyanobacteria that are capable of light absorption and charge separation can be utilized in hydrogen-producing devices that are driven by solar energy. As photosynthetic microorganisms, cyanobacteria present a unique opportunity for creating low cost systems for hydrogen production in vivo and in vitro . This review is focused on recent advances in cyanobacterial hydrogen research.
