Hydrogen production by different strains of Rhodobacter sphaeroides
Gündüz, Ufuk; Yucel, M; Turker, L; Eroglu, L (2000-06-15)
Utilisation of solar energy by photosynthetic microorganisms for H-2 production attracts much interest due to unlimited supply of energy. It is important to identify the most effective strain in terms of hydrogen production for the feasibility of the process. Four different strains of Rhodobacter sp. were grown in a water-jacketed cylindrical glass-column photobioreactor under anaerobic conditions. Growth characteristics and hydrogen production rates were determined. Comparison between strains of Rhodobacte...

Rhodobacter sphaeroides O.U.001 can produce hydrogen under anaerobic conditions and illumination. The objective of this study was to investigate the performance of an 81 flat plate solar bioreactor operating in outdoor conditions. Different organic acids were used as carbon sources (malate, lactate and acetate) and olive mill waste water was used as a sole substrate source. The consumption and the production of the organic acids were determined by HPLC. The accumulation of by-products, such as poly-beta-hyd...

Hydrogen gas production using coupled enzyme systems from E-coli and Halobacterium halobium
Kaya, B; Gündüz, Ufuk; Eroğlu, İnci; Turker, L; Yucel, M (1996-06-28)
A photobioreactor containing enzyme systems from E.coli and Halobacterium halobium for hydrogen gas production was constructed. Bacteriorhodopsin is a retinal protein present in the purple membrane fragment of photosynthetic bacteria H. halobium which behaves as a light driven proton pump upon illumination. The H+ ion gradient produced between interior and exterior of the cell membrane utilized by the bacterial cell for synthesis of ATP as an energy source for its growth and survival. Under anaerobic growth...
