Hydrogen produced by microorganisms, usually referred to as biohydrogen, offers a sustainable route for a green, sustainable fuel since it can be obtained from renewable resources such as sunlight and organic nutrients, under relatively mild operating conditions. Many genera of microorganisms are capable of hydrogen production when subjected to the right environmental factors. Among hydrogen-producing organisms, photosynthetic bacteria (also called photofermentative bacteria) are promising, as they use sunlight as their energy source and are able to grow and produce hydrogen using diverse types of substrates by virtue of their flexible and robust metabolism. A review of the past research and future directions for the microbial hydrogen production studies of the Middle East Technical University, Biohydrogen Group are reviewed.
