Photoelectrochemical H-2 production by using bacteriorhodopsin immobilized in PAG Yucel, M; El-Bashiti, T; Eroğlu, İnci; Sediroglu, V; Turker, L; Gündüz, Ufuk (2000-06-15) Bacteriorhodopsin (BR), a protein found in the purple membrane of Halobacterium halobium is used as a biocatalyst in photoelectrochemical hydrogen production in a NaCl solution. In present study the biocatalytic effect of BR of a new strain MILTU and strain S-9 were investigated in immobilized membranes The photoelectrochemical hydrogen production experiments were performed in a batch type glass reactor with free H. halobium packed cells or H halobium cells immobilized in polyacrylamide gel (PAG). It was fo...
Photoelectrochemical hydrogen production by using halobacterium halobium Sediroğlu, Vedat; Eroğlu, İnci; Yücel, Meral; Department of Chemical Engineering (1997)
Photoelectrochemical hydrogen production by Halobacterium halobium Sediroglu, V; Yucel, M; Gunduz, L; Turker, L; Aydemir, A; Eroğlu, İnci (1996-06-28) A bio-photoelectrochemical reactor has been designed and constructed in order to understand the biocatalytic effect of Halobacterium halobium on the electrochemical production of hydrogen in salt solution. Photoelectrochemical studies were carried out at 25 degrees C in 20 % NaCl solution containing 0.68 mu M bacteriorhodopsin. The reactor was illuminated by a 1000 W projector lamp which was 50 cm apart.
Photoelectrochemical cell using dye sensitized zinc oxide nanowires grown on carbon fibers Ünalan, Hüsnü Emrah; Suzuki, Kenichi; Dalal, Sharvari; Hiralal, Pritesh; Matsumoto, Hidetoshi; Imaizumi, Shinji; Minagawa, Mie; Tanioka, Akihiko; Flewitt, Andrew J.; Milne, William I.; Amaratunga, Gehan A. J. (AIP Publishing, 2008-09-29) Zinc oxide (ZnO) nanowires (NWs) grown on carbon fibers using a vapor transport and condensation approach are used as the cathode of a photoelectrochemical cell. The carbon fibers were obtained by electrospray deposition and take the form of a flexible carbon fabric. The ZnO NW on carbon fiber anode is combined with a "black dye" photoabsorber, an electrolyte, and a platinum (Pt) counterelectrode to complete the cell. The results show that ZnO NW and carbon fibers can be used for photoinduced charge separat...
Photofermentative hydrogen production using dark fermentation effluent of sugar beet thick juice by Rhodobacter Capsulatus Özkan, Endam; Gündüz, Ufuk; Uyar, Başar; Department of Biotechnology (2011) Biological hydrogen production through integration of dark and photo-fermentation by using biomass is a promising alternative for energy supply problems. The main purpose of this study was to investigate photobiological H2 production by the purple non-sulfur (PNS) bacteria Rb. capsulatus on dark fermentation effluent of sugar beet thick juice (DFESBTJ). Presence of NH4+ in effluents is an important parameter since NH4+ inhibit the nitrogenase enzyme activity. Therefore, the influence of different NH4+ conce...
