For more than 100 years it was believed that bacteria were the only group responsible for the oxidation of ammonia. However, recently, a new strain of archaea bearing a putative ammonia monooxygenase subunit A (amoA) gene and able to oxidize ammonia was isolated from a marine aquarium tank. Ammonia-oxidizing archaea (AOA) were subsequently discovered in many ecosystems of varied characteristics and even found as the predominant causal organisms in some environments. Here, we summarize the current knowledge on the environmental conditions related to the presence of AOA and discuss the possible site-related properties. Considering these data, we deduct the possible niches of AOA based on pH, sulfide and phosphate levels. It is proposed that the AOA might be important actors within the nitrogen cycle in low-nutrient, low-pH, and sulfide-containing environments.

Inorganic antimony speciation using tungsten coil atom trap and hydride generation atomic absorption spectrometry Akay, Pınar; Ataman, Osman Yavuz; Department of Chemistry (2010) Antimony is a toxic element which is mostly found in two oxidation states (III and V) in environmental, biological and geological samples. Antimony may form various inorganic and organic compounds that exhibit differences in analytical behavior, toxicity and mobility; inorganic compounds of antimony are more toxic than organic forms and toxicity of Sb(III) has been shown to be 10 times higher than that of Sb(V). Therefore selective determination of Sb(III) and Sb(V) is required in environmental and biologic...
Behaviour and control of listeria innocua during manufacture and storage of Turkish white cheese Öztürkoğlu, Şebnem; Gürakan, Candan; Department of Food Engineering (2004) Growth and survival of L. innocua and TAC in artificially inoculated Turkish White Cheese during manufacturing and storage periods, with respect to different level of contamination of L. innocua were investigated. Cheese products were manufactured by the short-set procedure in pilot-plant-sized vats, as in AOÇ dairy factory. Pasteurized cow̕s milk was inoculated with L. innocua for obtaining the initial loads of 3.84 and 7.12 log CFU/ml. Bacterial load of inoculated milk, whey, post-ripened curd and post-sa...
Diesel Oil Degradation Potential of a Bacterium Inhabiting Petroleum Hydrocarbon Contaminated Surface Waters and Characterization of Its Emulsification Ability Onur, Gozde; Yılmaz, Fadime; İçgen, Bülent (Wiley, 2015-07-01) Degradation of poorly water soluble hydrocarbons, like n-alkanes and polycyclic aromatic hydrocarbons are challenged by some bacteria through emulsification of hydrocarbons by producing biosurfactants. In diesel oil bioremediation, diesel oil degrading and surfactant producing bacteria are used to eliminate these pollutants from contaminated waters. Therefore, identifying and characterizing bacteria capable of producing surfactant and degrading diesel oil are pivotal. In this study, bacteria isolated from h...
PARTICULATE MATTER FORMATION DURING CO-COMBUSTION OF AGRICULTURAL RESIDUES WITH TURKISH LIGNITE USING A DROP TUBE FURNACE Kazanç Özerinç, Feyza (2019-09-01) This study investigates the particulate matter formation during combustion of olive residue, almond shell, and Tunçbilek lignite. Selected fuels (olive residue and Tunçbilek lignite) were also co-fired to evaluate the influence on particulate matter emission. Olive residue was ground to different size ranges (< 125 µm and 212–300 µm) to investigate the influence of the particle size and blended in different ratios of biomass / coal to analyse the interactions between fuels. Tests were performed in a drop tu...
Anaerobic treatment of opium alkaloid wastewater and effect of gamma-rays on anaerobic treatment Özdemir, Recep Tuğrul; Dilek, Filiz Bengü; Department of Environmental Engineering (2006) In this study, anaerobic treatability of opium alkaloid wastewater and the effect of radiation pretreatment (gamma-rays) on anaerobic treatability were investigated. Biochemical Methane Potential (BMP) assay was performed with alkaloid wastewater having initial COD values of 2400, 6000 and 9600 mg/L with and without basal medium (BM). The highest anaerobic treatment efficiency of 77% was obtained in the BMP reactor containing alkaloid wastewater with initial COD of 9600 mg/L and BM. Co-substrate use was inv...
