Biological production of hydrogen has been investigated over the past 30 years with the ultimate goal of providing a clean, carbon-neutral fuel. However, based on an extensive literature search and the recommendations of several recent DOE- and DOD-sponsored expert review panels it is obvious that an important element of this research has been largely overlooked - the physiology and diversity of naturally occurring, H2-producing bacteria. The main objective of this project was to develop a technique to extensively screen nitrogen fixing bacteria isolated from unique environments suspected of H2 production. Those showing H2-producing activity were tested on latex based mats, which could provide active centers of fuel cells. Specific objectives of the project were to establish a biofuels laboratory at the Aiken County Center for Hydrogen Research, where the following activities were persued.1) Develop a semi-automated apparatus to screen hundreds of bacteria in a short time; 2) Identify bacteria capable of producing hydrogen at rates sufficiently high to power a fuel cell. 3) Embed specific bacteria with high hydrogen production potentials into latex mats that can be incorporated in fuel cells applicable to a variety of industrial settings. During this project we developed screening techniques which include colorimetric and gas chromatographic assays for hydrogen production by bacterial isolates. Isolates were characterized both metabolically and genetically and preserved for future use. Isolates found to produce significant amounts of hydrogen were screened for activity under various environments. Potential isolates were then embedded in latex coatings and assayed for hydrogen production under different environmental conditions
