Elimination of the flavodiiron electron sink facilitates long-term H₂ photoproduction in green algae.

ABSTRACT:

Background

The development of renewable and sustainable biofuels to cover the future energy demand is one of the most challenging issues of our time. Biohydrogen, produced by photosynthetic microorganisms, has the potential to become a green biofuel and energy carrier for the future sustainable world, since it provides energy without CO₂ emission. The recent development of two alternative protocols to induce hydrogen photoproduction in green algae enables the function of the O₂-sensitive [FeFe]-hydrogenases, located at the acceptor side of photosystem I, to produce H₂ for several days. These protocols prevent carbon fixation and redirect electrons toward H₂ production. In the present work, we employed these protocols to a knockout Chla
