Heterotrophic growth and oil production from Micractinium sp. ME05 using molasses
Engin, Iskin Kose; Çekmecelioğlu, Deniz; Yücel, Ayşe Meral; Öktem, Hüseyin Avni (2018-12-01)
In this study the thermo-resistant green alga Micractinium sp. ME05 was cultivated in media containing molasses as a carbon source. Shake flask experiments and 2-L bioreactor experiments were conducted at different inoculu...
Microarray analysis of high light intensity stress on hydrogen production metabolism of Rhodobacter capsulatus
Gürgan Eser, Muazzez; Koku, Harun; Eroğlu, İnci; Yücel, Ayşe Meral (2018-07-28)
Enhancement of Heterotrophic Biomass Production by Micractinium sp ME05
Engin, Iskin Kose; Çekmecelioğlu, Deniz; Yücel, Ayşe Meral; Öktem, Hüseyin Avni (2018-05-01)
In this study, heterotrophic growth conditions for Micractinium sp. ME05 cells were investigated for the improvement of biomass production. Plackett Burman (PB) method was used to screen process variables, namely, pH, carb...
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...
Evaluation of heterotrophic and mixotrophic cultivation of novel Micractinium sp ME05 on vinasse and its scale up for biodiesel production
Engin, Iskin Kose; Çekmecelioğlu, Deniz; Yücel, Ayşe Meral; Öktem, Hüseyin Avni (2018-03-01)
Direct disposal of vinasse, a by-product of molasses fermentation plants, threatens environmental health. This study investigated the usage of vinasse as a nutrient source for the heterotrophic and mixotrophic cultivation ...
Single-stage photofermentative biohydrogen production from sugar beet molasses by different purple non-sulfur bacteria
Sagir, Emrah; Ozgur, Ebru; Gündüz, Ufuk; Eroglu, Inci; Yücel, Ayşe Meral (2017-11-01)
Biohydrogen production via fermentative routes offers considerable advantages in waste recycling and sustainable energy production. This can be realized by single-stage dark or photofermentative processes, or by a two-stag...
Long-term biological hydrogen production by agar immobilized Rhodobacter capsulatus in a sequential batch photobioreactor
Elkahlout, Kamal; Alipour, Siamak; Eroglu, Inci; Gündüz, Ufuk; Yücel, Ayşe Meral (2017-04-01)
In this study, agar immobilization technique was employed for biological hydrogen production using Rhodobacter capsulatus DSM 1710 (wild type) and YO3 (hup-mutant) strains in sequential batch process. Different agar and gl...
Evaluation of novel thermo-resistant Micractinium and Scenedesmus sp for efficient biomass and lipid production under different temperature and nutrient regimes
Sonmez, Cagla; ELÇİN, EVRİM; Akin, Dilan; Öktem, Hüseyin Avni; Yücel, Ayşe Meral (2016-07-01)
Despite the vast interest in microalgae as feedstock for biodiesel production, relatively few studies examined their response to diurnal temperature fluctuation. Here, we describe biomass and lipid productivities and fatty...
Enhanced salt tolerance of transgenic tobacco expressing a wheat salt tolerance gene
KAVAS, MUSA; BALOĞLU, MEHMET CENGİZ; Yücel, Ayşe Meral; Öktem, Hüseyin Avni (2016-01-01)
Soil salinity is one of the most important limiting factors of agricultural productivity in the world. The Triticum aestivum salt tolerance-related gene (TaSTRG) possesses a functional response to salt and drought stress c...
Hydrogen production by hup(-) mutant and wild-type strains of Rhodobacter capsulatus from dark fermentation effluent of sugar beet thick juice in batch and continuous photobioreactors
Uyar, Basar; Gurgan, Muazzez; Ozgur, Ebru; Gündüz, Ufuk; Yücel, Ayşe Meral; Eroglu, Inci (2015-10-01)
Photofermentative production of hydrogen is a promising and sustainable process; however, it should be coupled to dark fermentation to become cost effective. In order to integrate dark fermentation and photofermentation, t...
