There are many biological paths to hydrogen production, each with potential advantages, but also with its own challenges to implementation. Nonsulfur photosynthetic bacteria are able to capture solar energy and use it to drive the nearly complete conversion of substrate to hydrogen and carbon dioxide in a process called photofermentation. These organisms, which have the potential capacity to use a variety of feedstocks, are well known for their light-driven conversion of organic acids to hydrogen and carbon dioxide. Thus, they are ideal candidates for two-stage or coculture systems that derive additional hydrogen from the effluents of dark fermentations. In addition, various industrial and agricultural waste streams rich in organic acids can potentially serve as substrates for photofermentation. The metabolic and enzymatic properties underlying photofermentation, as well as possible waste streams that may be used successfully, are reviewed. Recent progress, including the use of immobilized systems and metabolic engineering, is highlighted.

In combating global warming and other environmental issues over the use of fossil fuels, extensive research has been focusing on developing hydrogen production from biological processes. Biohydrogen is considered a promising future biofuel because of its intrinsic clean and high-energy content properties and the way it is produced. In addition to being produced through environmentally friendly biological means, its conversion to energy yields only pure water, which is an ideal energy carrier in reducing greenhouse gas emissions from fossil fuel combustion. Unlike other well-developed biofuels such as bioethanol and biodiesel, biohydrogen production is still in the early stage of development. A variety of technologies are being developed for biohydrogen production. This chapter presents a review of the state-of-the-art and perspectives of bioprocess design for biohydrogen production research in the context of pathways, microorganisms, metabolic flux analysis, process design, and reactor system. Challenges and prospects of biohydrogen production are also outlined.
