Biohydrogen production using dark and photo fermentation: A mini review

摘要

Biological production of hydrogen is the most environmental friendly method in producing hydrogen, a clean fuel which produces only water upon combustion. There are many references available on biohydrogen production. This paper presents a review on current biological hydrogen production focusing on dark and photo fermentation processes. Limitation for hydrogen production such as source of substrate, type of microorganism employed and operational parameter are discussed in this paper.
