Aromatic ring hydroxylating dioxygenases (ARHDs), harboured by a variety of bacteria, catalyze the initial reaction in the degradation of a wide range of toxic environmental contaminants like aromatic and polycyclic aromatic hydrocarbons (PAHs). Regardless of the source, bacteria harbouring RHDs play major role in the removal of these toxic contaminants. The diversity of ARHDs in contaminated sites is supposed to be huge. However, most of the ARHD diversity studies are based on the PAH degraders and the ARHD diversity in the monoaromatic hydrocarbon degraders has not fully explored yet. In this study, therefore, the ARHD gene from nine different genara of the monoaromatic hydrocarbon degraders including Raoultella, Stenotrophomons, Staphylococcus, Acinetobacter, Pseudomonas, Serratia, Comamonas, Pantoea, and Micrococcus was analysed through polymerase chain reactions and sequencing. The sequence alignments of the ARHD amplicons with 81%-99% homologies were found to be highly related and held by divergent evolution from a common ancestor.

Use of cadA-Specific Primers and DNA Probes as Tools to Select Cadmium Biosorbents with Potential in Remediation Strategies İçgen, Bülent (Springer Science and Business Media LLC, 2016-05-01) Biosorption, using cadmium-resistant bacterial isolates, is often regarded as a relatively inexpensive and efficient way of cleaning up wastes, sediments, or soils polluted with cadmium. Therefore, many efforts have been devoted to the isolation of cadmium-resistant isolates for the efficient management of cadmium remediation processes. However, isolation, identification and in situ screening of efficient cadmium-resistant isolates are primary challenges. To overcome these challanges, in this study, cadA, c...
High-rate anaerobic treatment of digestate using fixed film reactors Ülgüdür, Nilüfer; Bayramoğlu, Tuba Hande; Uludağ-Demirer, Sibel; Demirer, Göksel (Elsevier BV, 2019-09-01) The effluent stream of the anaerobic digestion processes, the digestate, accommodates high residual organic content that needs to be further treated before discharge. Anaerobic treatment of digestate would not only reduce the residual organic compounds in digestate but also has a potential to capture the associated biogas. High-rate anaerobic reactor configurations can treat the waste streams using lower hydraulic retention times which requires less footprint opposed to the conventional completely stirred t...
Characterization of SDS-degrading Delftia acidovorans and in situ monitoring of its temporal succession in SDS-contaminated surface waters YILMAZ, Fadime; İçgen, Bülent (Springer Science and Business Media LLC, 2014-06-01) Incomplete removal of sodium dodecyl sulfate (SDS) in wastewater treatment plants may result in SDS residues escaping and finding their way into receiving water bodies like rivers, lakes, and sea. Introduction of effective microorganisms into the aerobic treatment facilities can reduce unpleasant by-products and SDS residues. Selecting effective microorganisms for SDS treatment is a big challenge. Current study reports the isolation, identification, and in situ monitoring of an effective SDS-degrading isola...
Trace level determination of beryllium in natural and flavored mineral waters after pre-concentration using activated carbon KILINÇ, ERSİN; Bakirdere, Sezgin; YAMAN, MEHMET (Informa UK Limited, 2011-01-01) The concentrations of beryllium (Be) in natural and flavored mineral water samples were determined by flame atomic absorption spectrophotometer (FAAS) after pre-concentration based on the complexation of Be(+2) with a mixture of acetylacetone (pentane-2,4-dione) plus morin (3,5,7,2',4'-pentaoxyflavone) and adsorption on activated carbon. The adsorbed complex was eluted with 1.5 ml of 2.0 M HNO(3) and evaporated to dryness. After adding 1.5 ml of 2 M HNO(3) and centrifuging, Be in acid solution was determine...
Effects of anaerobic digestion enhanced by ultrasound pretreatment on the fuel properties of municipal sludge Çelebi, Emrehan Berkay; Aksoy, Ayşegül; Sanin, Faika Dilek (Springer Science and Business Media LLC, 2020-05-01) In this study, effects of ultrasound pretreatment on combustion characteristics and elemental composition of municipal sludge were examined for energy-based evaluation of sludge pretreatment. Waste activated sludge (WAS) from a municipal wastewater treatment plant was pretreated with ultrasound at varying durations and was subjected to anaerobic digestion in a biochemical methane potential (BMP) assay. Changes in gas production rates, calorific value (CV), elemental compositions, and ash contents of sludge ...
