bizim ülkemizde yeterince değerlendirilmemektedir. Ülkemizde tarımsal ve hayvancılık üretimlerinin sürekli olarak artmasıyla bu ürünlerin atıklarda artmaktadır. Aynı şekilde ülkemizde nüfusun sürekli artma eğiliminde olmasıyla organik atık miktarı da artmaktadır. Ülkemizde özellikle başkent Ankara ilinde organik atık potansiyelinin oldukça fazla olması nedeniyle biyogaz üretim potansiyeli dikkat çekmektedir. Bu çalışmada ülke nüfusunun büyük bir kısmını barındıran Ankara ilinin hayvansal atıklar, mutfak atıkları, atık su arıtma tesisi atıkları ve tarımsal atıkları dikkate alınarak bu atıklardan biyogaz üretim miktarı belirlenmiştir. Sonuç olarak bu çalışmada Ankara'da organik atıklardan üretilebilecek teorik biyogaz enerji değeri m 3 /gün olarak değerlendirilmiştir. Major Organic Waste Sources in Ankara for Biogas Production AbstractBiogas production is important in terms of energy recovery and elimination of organic wastes. Organic wastes and industrial wastewater used as substrates in biogas production worldwide are not sufficiently evaluated in our country. In our country, agricultural and livestock production continuously increases with organic wastes. Similarly, the population of our country continuously tends to increase, thus the amount of organic waste is also increasing. Biogas production potential attracts attention due to the fact that the potential of organic waste in our country is very high especially in the capital city of Ankara. In this study, the amount of biogas production from these wastes was determined by considering the animal wastes, kitchen wastes, wastewater treatment plant wastes and agricultural wastes of Ankara, which has a large part of the country's population. As a result, the theoretical biogas energy value that can be produced from organic wastes in Ankara was evaluated as m 3 / day in this study. 277.348 m 3 /day from animal wastes, 9.789.180 m 3 /day from waste water treatment sludge, 38.493 m 3 /day from agricultural wastes, 160.380 m 3 /day from kitchen wastes have been found.

“…As can be seen in Figure 4, the great majority of methane was produced in the first 2 weeks and thereafter only small amounts of gas were released. The cumulative methane curves generally follow first order kinetics, since the hydrolysis process is the rate limiting process [27,28]. Whereas DM and VS are quantitative parameters for methane production potentials, BMP is the quality parameter that is reflected of bioconversion of organic compositions, which have dependency of methane potentials of each organic composition and its BD.…”

“…Hydrolysis is a step involving the enzyme-mediated chemical/biochemical transformation of long chain polymeric organic matter such as lipids, polysaccharides, protein, nucleic acids and fats into soluble and smaller organic molecules that can be consumed by microorganisms during the fermentation stage. These soluble components include fatty acids, monosaccharides, amino acids, simple aromatics and other short chain compounds [31,32]. Hydrolysis is catalyzed by the extracellular enzymes excreted by the microorganisms responsible for fermentation/acidogenesis [32][33][34].…”

This article reviews the experimental and theoretical studies conducted on the possible effects of oxygen in biogas generating anaerobic digesters. The interactions of oxygen with various biochemical processes associated with anaerobic digestion are discussed together with other relevant aspects. The conventional perception of oxygen being merely toxic in anaerobic digestion (AD) is refuted. Digesters can withstand significant levels of oxygenation without drastic negative impacts. Limited quantities of oxygen can even lead to improved AD reactor performance under certain operating conditions. Co-existence of anaerobic and aerobic cultures in a single bioreactor environment has been demonstrated. It is shown that the partial aeration assisted AD can serve as a beneficial treatment strategy for simultaneous waste treatment and energy generation, for a multitude of organic waste categories.
