The technology of biological hydrogen production by microalgae

Hydrogen is an ideal cleaning becomes more and more important in the energy. research Microalgae photosynthetic hydrogen production of new energy. In this review, the biological principles were presented, focusing on hydrogen production mechanism of nitrogenase and reversible hydrogenase. The one-stage and two-stage indirect biophotolysis by reversible hydrogenase based on sulfur-deprived culture were discussed. It is concluded that the two-stage one holds the greatest potential for the future development. The limiting factors and problems for realizing this potential were also analyzed. High-effective hydrogen production algae and photo bioreactor were required to realize large-scale hydrogen production by microalgea.
