Electrical current generation in microbial electrolysis cells by hyperthermophilic archaea Ferroglobus placidus and Geoglobus ahangari
Yılmazel Tokel, Yasemin Dilşad; Zhu, Xiuping; Kim, Kyoung-Yeol; Holmes, Dawn E.; Logan, Bruce E. (2018-02-01)
Few microorganisms have been examined for current generation under thermophilic (40-65 degrees C) or hyperthermophilic temperatures (>= 80 degrees C) in microbial electrochemical systems. Two iron-reducing archaea from the...
Effect of pre-acclimation of granular activated carbon on microbial electrolysis cell startup and performance
LaBarge, Nicole; Yılmazel Tokel, Yasemin Dilşad; Hong, Pei-Ying; Logan, Bruce E. (2017-02-01)
Microbial electrolysis cells (MECs) can generate methane by fixing carbon dioxide without using expensive catalysts, but the impact of acclimation procedures on subsequent performance has not been investigated. Granular ac...
Impact of acclimation methods on microbial communities and performance of anaerobic fluidized bed membrane bioreactors
LaBarge, Nicole; Ye, Yaoli; Kim, Kyoung-Yeol; Yılmazel Tokel, Yasemin Dilşad; Saikaly, Pascal E.; Hong, Pei-Ying; Logan, Bruce E. (2016-01-01)
An anaerobic fluidized bed membrane bioreactor (AFMBR) is a new and effective method for energy-efficient treatment of low strength wastewater, but the factors that affect performance are not well known. Different inocula ...
Hyperthermophilic hydrogen production from wastewater biosolids by Caldicellulosiruptor bescii
Yılmazel Tokel, Yasemin Dilşad; Johnston, David; Duran, Metin (Elsevier BV, 2015-09-28)
Wastewater biosolids are abundant renewable resources that are rich in organic matter and offer a low cost potential feedstock for biohydrogen production. Relevant literature indicates that biosolids conversion rates are r...
Is aceticlastic methanogen composition in full-scale anaerobic processes related to acetate utilization capacity?
Yilmaz, Vedat; Ince-Yilmaz, Ebru; Yılmazel Tokel, Yasemin Dilşad; Duran, Metin (Springer Science and Business Media LLC, 2014-06-01)
In this study, biomass samples were obtained from six municipal and nine industrial full-scale anaerobic processes to investigate whether the aceticlastic methanogen population composition is related to acetate utilization...
Nitrogen and phosphorus recovery from anaerobic co-digestion residues of poultry manure and maize silage via struvite precipitation
Yılmazel Tokel, Yasemin Dilşad; Demirer, Goksel N. (SAGE Publications, 2013-08-01)
Anaerobic digestion is commonly used for the stabilization of agricultural and animal wastes. However, owing to the stringent environmental criteria, anaerobic digester effluents need to be further treated to reduce nutrie...
Anaerobic co-digestion of sewage sludge and primary clarifier skimmings for increased biogas production
Alanya, S.; Yılmazel Tokel, Yasemin Dilşad; Park, C.; Willis, J. L.; Keaney, J.; Kohl, P. M.; Hunt, J. A.; Duran, M. (IWA Publishing, 2013-01-01)
The objective of the study was to identify the impact of co-digesting clarifier skimmings on the overall methane generation from the treatment plant and additional energy value of the increased methane production. Biogas p...
Removal and recovery of nutrients as struvite from anaerobic digestion residues of poultry manure
Yılmazel Tokel, Yasemin Dilşad; Demirer, G. N. (Informa UK Limited, 2011-01-01)
The removal and the recovery of nutrients, namely nitrogen (N) and phosphorus (P) from anaerobically digested and solid-liquid separated manure effluents via struvite precipitation were investigated. Both the liquid and th...
The determination of fertilizer quality of the formed struvite from effluent of a sewage sludge anaerobic digester
UYSAL, Ayla; Yılmazel Tokel, Yasemin Dilşad; DEMİRER, GÖKSEL NİYAZİ (2010-09-15)
The formation of struvite (MgNH4PO4 center dot 6H(2)O) in wastewater treatment plants can lead to scaling and thus operational problems reducing the treatment efficiency. However, struvite has significant commercial value ...
