In this study, anaerobic treatability and biogas generation potential of broiler and cattle manure were investigated. For this purpose, seven sets of anaerobic batch reactor experiments were performed using broiler and cattle manure and their mixtures in five different ratios (100% broiler; 75% broiler, 25% cattle; 50% broiler, 50% cattle; 25% broiler, 75% cattle; 100% cattle). These manure mixtures had two different initial chemical oxygen demand (COD) (12,000 and 53,500 mg/l) concentrations. The effects of initial COD concentration, nutrient and trace metal supplementation, microbial acclimation and digestion temperature were investigated. Results revealed that the efficiency of total COD removal was 32.0-43.3% and 37.9-50% for initial COD concentrations of 12,000 and 53,500 mg/l, respectively. The biogas yields observed for initial COD concentrations of 12,000 and 53,500 mg/l were 180-270 and 223-368 ml gas/g COD added, respectively. A decrease in biogas yield was observed as the fraction of broiler manure increased in mixture of broiler and cattle manure at initial COD values of 53,500 mg/l.

ENHANCEMENT OF BIOMETHANE PRODUCTION FROM CATTLE MANURE VIA GRANULAR ACTIVATED CARBON AMENDMENT Odabaş, Yasin; Yılmazel Tokel, Yasemin Dilşad; Department of Environmental Engineering (2022-11) In this study we investigated the impact of granular activated carbon (GAC) application on anaerobic digestion (AD) process of cattle manure. Firstly, the effect of the presence of basal medium on cattle manure digestion was evaluated. It was observed that basal medium addition decreased methane yield and increased lag time. Then, for the enhanced cattle manure digestion, a metal-based conductive material, hematite (Fe2O3), and carbon-based material, GAC, were amended into the reactors. From the comparison ...
Effect of retention time and organic loading rate on anaerobic acidification and biogasification of dairy manure Demirer, Göksel Niyazi; Chen, S (2004-12-01) Vast amounts of animal manure produced from concentrated animal feeding operations have the potential to be converted into economic gain if the proper processing technology is employed. Anaerobic digestion (AD) is an effective way to convert organic wastes including animal manure into profitable by-products as well as to reduce the pollution of water, air, and soil caused by these wastes. Two-phase AD of manure offers several advantages over conventional one-phase AD. Solids reduction through hydrolysis/aci...
Effect of operational parameters on anaerobic co-digestion of dairy cattle manure and agricultural residues: A case study for the Kahramanmaras region in Turkey Alkaya, Emrah; Bayramoğlu, Tuba Hande; DEMİRER, GÖKSEL NİYAZİ (Wiley, 2010-12-01) The aim of this study was to investigate the effect of temperature and hydraulic retention time (HRT) on anaerobic co-digestion/biomethanation of cattle manure and agricultural residues (clover, grass and wheat straw). For this purpose, 12 semi-continuous reactors, fed with/without agricultural residues, were operated under varied temperature (10 +/-, 20 +/- and 35 +/- 1 degrees C) and HRT (20 and 30 days) conditions. During the experimental study, all reactors were fed once on a daily basis and operated wi...
IMPACT OF PROCESS CONDITIONS ON METHANE PRODUCTION IN ANAEROBIC DIGESTION AND MICROBIAL ELECTROLYSIS CELL (AD-MEC) INTEGRATED SYSTEMS Şanlı, Mert; Yılmazel Tokel, Yasemin Dilşad; Department of Environmental Engineering (2022-11-28) Anaerobic digestion (AD) is a common method used for treatment of complex wastes with additional benefit of biogas production. Yet, the process has several limitations such as slow kinetics, long start-up periods and low methane (CH4) production yield. With the integration of microbial electrolysis cells (MECs) into AD, it is anticipated that these limitations of AD will be reduced. The reasons of such improvements in the AD-MEC integrated systems may stem from the enhanced electron transfer in microbial co...
Effect of drought and salt stresses on the gene expression levels of antioxidant enzymes in lentil (lens culinaris m.) seedlings Aksoy, Emre; Yücel, Ayşe Meral; Department of Biology (2008) This study was carried out for understanding of antioxidant mechanisms of lentil under abiotic stress conditions. For this aim, 14 days old lentil seedlings (Lens culinaris Medik cv. Sultan-1) were subjected to drought (20% PEG 6000), and salt (150 mM NaCl ) stress for 6, 12 and 24 hours, for 3, 5 and 7 days. PCR conditions for Mn SOD, Cu/Zn SOD, chloroplastic/mitochondrial GR, CAT and chloroplast /stromal APX antioxidant enzymes were optimized. Then, total RNA was isolated from stressed and non-stressed pl...
