Abstract : The experimental investigation of microorganisms capable of producing hydrogen for subsequent fuel cell use is described. The microorganisms Clostridium welchii, Aeromonas hydrophila and Bacillus polymyxa were screened using various substrates. Rate studies with E. coli on maltose and glucose and Pseudomonas sp. (G4A) on formate and glucose were conducted. The manner in which hydrogen is produced demonstrates the desirability of following the course of reaction continually. Full factorial studies, with three factors at two levels, were conducted with several organism-substrate systems. Along with results obtained from previous factional factorial experiments, further definition of the criteria for maximizing hydrogen production has been established. Scale-up studies with E. coli-glucose show that the factors governing laboratory scale studies are applicable to large volume fermenters. (Author)
