Addressing challenges in the ultrafiltration of biomolecules from complex aqueous environments
Büküşoğlu, Emre; Koku, Harun; Çulfaz Emecen, Pınar Zeynep (Elsevier BV, 2020-04-01)
Substantial progress has been made in ultrafiltration processes toward the separation of colloidal species from aqueous environments. Studies, especially in the past decade, have advanced the separations using functional a...
Microarray analysis of high light intensity stress on hydrogen production metabolism of Rhodobacter capsulatus
Gurgan, Muazzez; Koku, Harun; EROĞLU, İNCİ; Yucel, Meral (Elsevier BV, 2020-01-29)
Biohydrogen obtained from purple non sulfur bacteria (PNSB) is an environmentally friendly alternative for hydrogen production. PNSB can be employed in large scale outdoor photobioreactors to produce hydrogen by photoferme...
Pilot-scale outdoor photofermentative hydrogen production from molasses using pH control
Oflaz, F. Betül; Koku, Harun (Elsevier BV, 2020-01-01)
© 2020 Hydrogen Energy Publications LLCThe duration of photofermentative hydrogen production from sugar-based nutrients is limited by gradual acidification caused by the production of organic acids, leading to suboptimal p...
Transcriptome analysis of the effects of light and dark cycle on hydrogen production metabolism of Rhodobacter capsulatus DSM1710
Gürgan, Muazzez; Koku, Harun; Eroglu, Inci; Yücel, Meral (Elsevier BV, 2020-01-01)
© 2020 Hydrogen Energy Publications LLCPhotosynthetic purple non sulfur bacteria can be utilized in outdoor photobioreactors for sustainable large-scale biohydrogen production. However, the diurnal cycle under natural outd...
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 fabri...

Photofermentative hydrogen production from molasses: Scale-up and outdoor operation at low carbon-to-nitrogen ratio
Savasturk, Dilan; Kayahan, Emine; Koku, Harun (2018-06-28)
Photofermentative hydrogen production was carried out under outdoor conditions with a Rhodobacter capsulatus strain on molasses, a renewable and sustainable feedstock. An existing photobioreactor design was scaled-up from ...
Biological hydrogen production from sugar beet molasses by agar immobilized R. capsulatus in a panel photobioreactor
ELKAHLOUT, Kamal; SAĞIR, EMRAH; ALIPOUR, Siamak; Koku, Harun; Gündüz, Ufuk; EROĞLU, İNCİ; Yücel, Ayşe Meral (2018-03-18)
Biohydrogen production from sugar beet molasses was investigated by using agar immobilized R. capsulatus YO3. A panel photobioreactor (1.4 L) was employed for a long-term hydrogen production in both indoor and outdoor cond...
Scale-up studies for stable, long-term indoor and outdoor production of hydrogen by immobilized Rhodobacter capsulatus
Sagir, EMRAH; ALIPOUR, Siamak; ELKAHLOUT, Kamal; Koku, Harun; Gündüz, Ufuk; Eroglu, Inci; YUCEL, Meral (2017-09-07)
Photofermentative hydrogen production by immobilized Rhodobacter capsulatus YO3 was carried out in a novel photobioreactor in sequential batch mode under indoor and outdoor conditions. Long-term H-2 production was realized...
