There are many biological paths to hydrogen production, each with potential advantages, but also with its own challenges to implementation. The nonsulfur photosynthetic bacteria use a process termed as photofermentation to harness solar energy for the close to stoichiometric conversion of various carbon substrates to hydrogen, releasing carbon dioxide. These organisms can potentially use various feedstocks, but are particularly adept at the light-driven production of hydrogen from organic acids. Thus they are ideal candidates for two-stage or coculture systems, which derive additional hydrogen from the effluents of dark fermentations or organic acid-rich agricultural and industrial waste streams. The possible waste streams, as well as the metabolic and enzymatic properties, underlying photofermentation are reviewed. Recent progress, including the use of immobilized systems and metabolic engineering, is highlighted.

Biohydrogen production from beet molasses by sequential dark and photofermentation Ozgur, Ebru; Mars, Astrid E.; Peksel, Beguem; Louwerse, Annemarie; Yucel, Meral; Gündüz, Ufuk; Claassen, Pieternel A. M.; Eroglu, Inci (2010-01-01) Biological hydrogen production using renewable resources is a promising possibility to generate hydrogen in a sustainable way. In this study, a sequential dark and photofermentation has been employed for biohydrogen production using sugar beet molasses as a feedstock. An extreme thermophile Caldicellulosiruptor saccharolyticus was used for the dark fermentation, and several photosynthetic bacteria (Rhodobacter capsulatus wild type, R. capsulatus hup(-) mutant, and Rhodopseudomonas palustris) were used for t...
Photofermentative hydrogen production from molasses in tubular photobioreactor with pH control Oflaz, Fatma Betül; Koku, Harun; Department of Chemical Engineering (2019) Biological hydrogen production has the potential to supply hydrogen from various wastes as feedstock and operation under ambient conditions. In order to obtain cost effective production, photobioreactors (PBRs) that can operate for long durations while utilizing waste are necessary. Two primary issues limiting the duration are decrease in pH and the non-optimal C/N ratio. The main aim of this study was to construct and operate a pH control system for a pilot scale photobioreactor (20 L) to achieve prolonged...
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...
Photobiological hydrogen production by Rhodobacter sphaeroides O.U.001 by utilization of waste water from milk industry Turkarslan, S; Yigit, DO; Aslan, K; Eroğlu, İnci; Gündüz, Ufuk (1997-06-26) Hydrogen production with photosynthetic microorganisms contributes to the protection of the environment, not only in producing a clean fuel but also in waste treatment processes. In this study, Rhodobacter sphaeroides, a photosynthetic bacteria, is used in photobiological hydrogen production by using waste water from the milk industry.
Long-term stable hydrogen production from acetate using immobilized Rhodobacter capsulatus in a panel photobioreactor Elkahlout, Kamal; Sagir, Emrah; Alipour, Siamak; Koku, Harun; Gündüz, Ufuk; Eroglu, Inci; Yucel, Meral (2019-07-12) Biological hydrogen production is attractive since renewable resources are utilized for hydrogen production. In this study, a novel panel photobioreactor (1.4 L) was constructed from Plexiglas with a network of nylon fabric support for agar immobilized bacteria complex. Two strains of Rhodobacter capsulatus DSM 1710 wild-type strain and Rhodobacter capsulatus YO3 (hup(-), uptake hydrogenase deleted mutant) with cell concentrations of 2.5 and 5.0 mg dcw/mL agar, respectively were entrapped by 4% (w/v) of aga...
