abstract
Due to increasing fuel prices and growing concerns of global warming, alternative energy sources need to be investigated. One such source is the harvesting of energy through the combustion of hydrogen gas. Current means of producing hydrogen gas are expensive. An alternative, and possibly less expensive, method to produce hydrogen gas is through biological processes. Anaerobic digester sludge from Cheyenne’s Dry Creek Water Reclamation Facility was enriched for purple non-sulfur bacteria (PNSB). Enriched PNSB were then used to produce molecular hydrogen (a) with artificial lighting at constant temperature; and (b) with natural lighting and temperature. For both experiments, the PNSB were fed a mixture of butyric and acetic acids. With controlled temperature and lighting indoors, the PNSB produced a maximum of 22.7% of the theoretical amount of molecular hydrogen that could have been produced. Outdoors, on top of the Physical Sciences building at the University of Wyoming, the PNSB produced a maximum of 0.72% of the theoretical amount of molecular hydrogen that could have been produced.
