Hydrogen has the potential to be a highly efficient fuel source. Its current production via steam reformation of natural gas, however, consumes a large amount of energy and gives off carbon dioxide. A newer method has since surfaced: using a microorganism's metabolism to drive hydrogen production. In this study, the conditions for maximum hydrogen production in Heliobacterium modesticaldum were identified and assessed. The cells were grown under varying conditions and their headspaces were sampled using a gas chromatogram to measure the amount of accumulated hydrogen during each condition.
