Photoproduction of hydrogen by Rhodobacter sphaeroides OU001
Arik, T; Gündüz, Ufuk; Yucel, M; Turker, L; Sediroglu, V; Eroğlu, İnci (1996-06-28)
A photobioreactor has been designed and constructed for hydrogen production by Rhodobacter. sphaeroides O.U.001 (DSM 5864). Two phases have been distinguished upon illumination at argon atmosphere, the growth phase and the hyrogen production phase. Anaerobic growth was observed at a wide range of pH (6-9) and temperature (25-40 degrees C) only under illumination. Rhodobacter sphaeroides O.U.001 photoproduced hydrogen after a certain limiting cell concentration has been reached, however, high cell mass cause...
Photoproduction of hydrogen from sugar refinery wastewater by Rhodobacter sphaeroides OU 001
Yetis, M; Gündüz, Ufuk; Eroglu, I; Yucel, M; Turker, L (2000-11-01)
Pretreated sugar refinery wastewater (SRWW) was used for the production of hydrogen by Rhodobacter sphaeroides O.U.001 in a 0.4 1 column photobioreactor. Hydrogen was produced at a rate of 0.001 1 hydrogen/h/l culture in 20% dilution of SRWW. To adjust the carbon concentration to 70 mM and nitrogen concentration to 2 mM, sucrose or l-malic acid was added as carbon source and sodium glutamate was added as nitrogen source to the 20% dilution of SRWW. By these adjustments, hydrogen production rate was increase...
Photoproduction of hydrogen by Rhodobacter capsulatus from thermophilic fermentation effluent
Uyar, Basar; Schumacher, Matthias; Gebicki, Jakub; Modigell, Michael (2009-08-01)
Rhodobacter capsulatus was used for the phototrophic hydrogen production on effluent solution derived from the thermophilic fermentation of Miscanthus hydrolysate by Thermotoga neapolitana. Pretreatments such as centrifugation, dilution, buffer addition, pH adjustment and sterilization were suggested for the effluent before being fed to the photofermentation. Batch-wise experiments showed that R. capsulatus grows and produces hydrogen on the pretreated effluent solution. Moreover, it was found that the hydr...
