Photofermentation

Photofermentation

Photofermentation is the fermentative conversion of organic substrate to biohydrogen manifested by a diverse group of photosynthetic bacteria by a series of biochemical reactions involving three steps similar to anaerobic conversion. Photofermentation differs from dark fermentation because it only proceeds in the presence of light.

For example photo-fermentation with Rhodobacter sphaeroides SH2C can be employed to convert small molecular fatty acids into hydrogen [ [http://cat.inist.fr/?aModele=afficheN&cpsidt=18477081 High hydrogen yield from a two-step process of dark-and photo-fermentation of sucrose] ] .
