Hydrogen productivities of different photosynthetic bacteria have been searched on real thermophilic dark fermentation effluents (DFE). The results obtained with potato steam peels hydrolysate (PSP) DFE were compared to glucose DFE. Photobiological hydrogen production has been carried out in indoor, batch photobioreactors using several strains of purple non-sulfur (PNS) bacteria such as Rhodobacter capsulatus (DSM1710), Rhodobacter capsulatus hup- (YO3), Rhodobacter sphaeroides O.U.001 (DSM5864), Rb. sphaeroides O.U.001 hup- and Rhodopseudomonas palustris.
