What are the regulatory and metabolic pathways that influence H2 production?
A thorough examination of hydrogen metabolism in green algae and several different strains of cyanobacteria from diverse habitats will provide new insights into how hydrogen production pathways are controlled. By understanding how an organism sustains and regulates hydrogen-production, we will be able to determine which metabolic pathways contribute, how eliminating hydrogen-consuming reactions affects hydrogen metabolism and other cellular processes, and how organisms can be adapted to increase hydrogen yields.
