Fermentative hydrogen production

Fermentative hydrogen production is the fermentative conversion of organic substrate to biohydrogen manifested by a diverse group of bacteria using multi enzyme systems involving three steps similar to anaerobic conversion. Dark fermentation reactions do not require light energy, so they are capable of constantly producing hydrogen from organic compounds throughout the day and night. Using synthetic biology, the bacteria are usually genetically altered[1][2].

Photofermentation differs from dark fermentation because it only proceeds in the presence of light. Electrohydrogenesis is used in microbial fuel cells.

For example photo-fermentation with Rhodobacter sphaeroides SH2C can be employed to convert small molecular fatty acids into hydrogen[3].
