Fermentative microorganisms utilizing organic compounds in wastewater provide a renewable, low-cost source of hydrogen gas for fuel cells. Hydrogen production in continuous-flow bioreactors using mixed microbial populations from heat-treated soil was studied. Bioreactors, fed with synthetic wastewater containing glucose, were maintained at pH 5.5 to inhibit formation of methane from H 2. Microbial community fingerprinting of DNA extracted from bioreactor material consistently detects Clostridia spp. belonging to Cluster I. This is an abstract of a paper presented at the 228th ACS National Meeting (Philadelphia, PA 8/22-26/2004).
