Photobioreactor for hydrogen production

[Sagaa]

What are the modifications should be made in the photobioreactor for hydrogen production?

[Mak]

The hydrogen productivity of a photobioreactor is light limited and tends to decrease at higher light intensities (Photosynthesis diverts the hydrogen production pathway) hence the light regime is determined by the light gradient (must be diluted and distributed as much as possible; absolute dark condition responsible for highest production). Liquid circulation time or aeration (hydrogen producing enzymes are oxygen susceptible; anaerobic condition or inert gas environment is preferred) rate has something to do with hydrogen productivity.
