Biohydrogen production from cattle manure and its mixtures with renewable feedstock by hyperthermophilic Caldicellulosiruptor bescii Yılmazel Tokel, Yasemin Dilşad (Elsevier BV, 2021-04-10) © 2021 Elsevier LtdFermentation of cattle manure as the sole carbon source and along with the mixtures of switchgrass and wastewater biosolids by hyperthermophilic cellulolytic bacterium, Caldicellulosiruptor bescii was assessed for the first time in the literature. When cattle manure was used as the sole carbon source, a yield of 82.5 NmL/gVSadded was recorded and that is the highest yield reported from dark fermentation studies on cattle manure so far. The mixture of cattle manure with wastewater biosolid...
Biohydrogen production by immobilized purple nonsulfur bacteria Sağır, Emrah; Yücel, Ayşe Meral; Koku, Harun; Department of Biochemistry (2018) Biological hydrogen production by purple non-sulfur bacteria is an attractive route to build a large scale hydrogen production system in outdoor natural conditions from various renewable sources. In this study, biological hydrogen production was carried out by agar immobilized purple non-sulfur bacteria in indoor and outdoor conditions. A novel photobioreactor (1.4 L volume) was built and operated continuously for 20 to 64 days in sequential batch mode for long-term hydrogen production using agar-immobilize...
Biohydrogen production by Rhodobacter capsulatus on acetate at fluctuating temperatures Ozgur, Ebru; Uyar, Basar; Ozturk, Yavuz; Yucel, Meral; Gündüz, Ufuk; Eroglu, Inci (2010-03-01) Hydrogen is a clean energy alternative to fossil fuels. Photosynthetic bacteria produce hydrogen from organic compounds under anaerobic, nitrogen-limiting conditions through a light-dependent electron transfer process. In this study, the hydrogen production efficiency of phototrophic bacteria, Rhodobacter capsulatus and its Hup mutant strain (an uptake hydrogenase deleted strain) were tested on different initial acetate concentrations at fluctuating temperatures with indoor and outdoor photobioreactors. Ace...
Biohydrogen production by Rhodobacter capsulatus in solar tubular photobioreactor on thick juice dark fermenter effluent Boran, Efe; Ozgur, Ebru; Yucel, Meral; Gündüz, Ufuk; Eroglu, Inci (2012-08-01) The purpose of this study was to operate a pilot scale solar tubular photobioreactor (90 L) for photofermentative hydrogen production from thick juice dark fermenter effluent (DEE) by photosynthetic purple-non-sulfur bacterium, Rhodobacter capsulatus. The tubular photobioreactor was equipped with internal cooling tubes for effective temperature control, which is essential for stable, long-term operation. The photobioreactor was operated in fed-batch mode throughout September 2009 in Ankara, Turkey. R. capsu...
Biohydrogen production by Rhodobacter capsulatus Hup(-) mutant in pilot solar tubular photobioreactor Boran, Efe; Ozgur, Ebru; Yucel, Meral; Gündüz, Ufuk; EROĞLU, İNCİ (2012-11-01) In this study, a pilot solar tubular photobioreactor was successfully implemented for fed batch operation in outdoor conditions for photofermentative hydrogen production with Rhodobacter capsulatus (Hup(-)) mutant. The bacteria had a rapid growth with a specific growth rate of 0.052 h(-1) in the batch exponential phase and cell dry weight remained in the range of 1-1.5 g/L throughout the fed batch operation. The feeding strategy was to keep acetic acid concentration in the photobioreactor at the range of 20...
