Modified algae enzymes increasing hydrogen production

A peer-reviewed article published in the journal "Energy & Environmental Science", Enhancing hydrogen production of microalgae by redirecting electrons from photosystem I to hydrogenase, explains how researchers at Max Planck Society, discovered a way of increasing production of hydrogen gas by altering the algae enzyme.
According to an article published in phys.org by Max Planck Society, scientists discovered that only two amino acids of ferrous protein PETF are important for binding FNR. The ferrous protein PETF is responsible for transporting the electrons,  ferredoxin-NADP+ oxidoreductase (FNR), so that NADPH is formed and carbohydrates are synthesised from carbon dioxide.
The researchers thus modified the two amino acids of PETF. PETF was consequently unable to bind to FNR. Algae enzyme was therefore able to transfer more of its electrons to hydrogenase and less to FNR. Hydrogen production increased five times as a result.
Algae naturally generates hydrogen gas but in very small amounts. Research in hydrogen gas production is important because of the vision of using hydrogen gas as a fuel for say vehicles in stead of petroleum products such as diesel. More efficient ways of generating hydrogen gas in large amounts hence need to be found.
