UPTAKE HYDROGENASE IN CYANOBACTERIA
Morgan Snider, Grand Canyon University. Undergraduate Student
Photoautotrophic prokaryotic cyanobacteria are ideal models for microbial hydrogen production. Hydrogen is produced by nitrogenase and bidirectional hydrogenase. Uptake hydrogenase reduces the net gain of H2 through oxidation. The two genes that encode the subunits of uptake hydrogenase are hupS and hupL. Genetic deletion of it could greatly increase hydrogen production by cyanobacteria, and it will be the focus of this presentation.
