Producing Hydrogen Gas with Artificial Cells

Researchers at Uppsala University have recently synthesized an artificial enzyme that can use its own energy to produce hydrogen gas from solar energy. [FeFe]-Hydrogenase, the metalloenzyme that is used in this research, produces hydrogen with great catalytic abilities, and is therefore a main focus in bio-sustainable energies. They used its enzymatic maturation machinery and synthetically activated it in Synechocystis PCC 6803, a unicellular cyanobacterium that continually grows either by photosynthesis or heterotrophic growth. Hydrogenase is activated in the enzyme and linked to the metabolic processes in the cell, consequently producing hydrogen gas. Uppsala University has discovered that we can now use cells to produce hydrogen gas instead of water, and by using semi-synthetic cells we eliminate the need of biological regulation and maturation.
