Biological hydrogen production from olive mill wastewater and its applications to bioremediation
Eroğlu, Ela; Eroğlu, İnci; Department of Chemical Engineering (2006)
Hydrogen production by photosynthetic bacteria occurs under illumination in the presence of anaerobic atmosphere from the breakdown of organic substrates, which is known as photofermentation. In this study, single-stage and two-stage process development were investigated for photofermentative hydrogen production from olive mill wastewater by Rhodobacter sphaeroides O.U.001 within indoor and outdoor photobioreactors. It was proven that diluted olive mill wastewater (OMW) could be utilized for photobiological...
Biological hydrogen production by using co-cultures of PNS bacteria
Baysal, Görkem; Yücel, Ayşe Meral; Özgür, Ebru; Department of Biotechnology (2012)
Biological hydrogen production is a renewable, carbon-neutral and clean route for hydrogen production. Purple non-sulfur (PNS) bacteria have the ability to produce biohydrogen via photofermentation process. The type of the bacterial strain used in photofermentation is known to have an important effect on hydrogen yield. In this study, the effect of different co-cultures of PNS bacteria on photofermentation process was investigated in search of improving the hydrogen yield. For this purpose, growth, hydrogen...
Biological Hydrogen Production Studies in METU
Koku, Harun (2021-09-23)
Many kinds of microorganisms produce hydrogen under favorable conditions. Biologically produced hydrogen, or biohydrogen in short, is attractive due to the mild operating conditions, as well as the potential of using renewable sources and nutrients such as sunlight and agricultural feedstock. The Biohydrogen Group of the Middle East Technical University investigates the conditions, methods and solutions to improve biohydrogen production in order to ultimately achieve a technically and economically fe...
Biological hydrogen production from sugar beet molasses by agar immobilized R. capsulatus in a panel photobioreactor

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 conditions. The impact of several initial molasses concentrations on hydrogen production, yield and productivity were assessed. Indoor studies revealed that initial sucrose concentration in molasses should be kept below 20 mM to prevent inhibition of hydrogen production. The highest hydrogen p...
Biological treatment and nanofiltration of denim textile wastewater for reuse
ŞAHİNKAYA, Erkan; UZAL, Nigmet; Yetiş, Ülkü; Dilek, Filiz Bengü (2008-05-30)
This study aims at coupling of activated sludge treatment with nanofiltration to improve denim textile wastewater quality to reuse criteria. In the activated sludge reactor, the COD removal efficiency was quite high as it was 91 +/- 2% and 84 +/- 4% on the basis of total and soluble feed COD, respectively. The color removal efficiency was 75 +/- 10%, and around 50-70% of removed color was adsorbed on biomass or precipitated within the reactor. The high conductivity of the wastewater, as high as 8 mS/cm, did...
