Summary of the technology
Harvesting Solar Energy: Hydrogen production by a semi-artificial photo-system
Project ID : 6-2008-56
The Technology
An artificial ferredoxin-hydrogenase fusion enzyme (Fd-HydA) has been developed for the production of hydrogen gas in algae. The Fd-HydA fusion enzyme interferes with the formation of the naturally occurring ferredoxin-sugar production pathway in photosystem I (PSI) complex and shuttles the donated electrons directly to the hydrogenase as shown in in vitro studies. Preliminary expression of Fd-HydA in algae supports hydrogen production.
Stage of Development
These results suggest a new direction for improvement of biohydrogen production and a means to further resolve the mechanisms that control partitioning of photosynthetic electron transport.
