energy sources is a major issue that bridges the academic endeavors of the scientific community to the real problems of the global community. In this light, bio-hydrogen stands as a remarkably useful energy source for alleviating the pressures of limited resources as well as promoting the use of environmentally friendly technology. Produced from renewable resources such as water and organic wastes by biological means, it represents a hopeful effort to address some of the everyday problems that people meet in terms of basic energy needs across the
world. Various biological hydrogen production processes are in the R&D phase and substantial research is required to enable commercialization of technology. Several processes are currently
under development ranging from anaerobic fermentations to photobiological processes with a promising aspect for the economical feasibility. In this symposium, an overview of biological hydrogen production processes, such as dark anaerobic fermentation from organic wastes, photo-biolysis of water, photo-fermentation, and in vitro systems will be introduced briefly for their fundamental and applied research. In addition, the combination of two consecutive
fermentation processes, dark anaerobic fermentation of organic wastes and photo-fermentation, which is known to be the most economical and efficient technology for complete use of chemical energy in the substrate, will be presented in detail.
