Article Citation - WoS: 17Citation - Scopus: 24Resistance, bioaccumulation and solid phase extraction of uranium (VI) by Bacillus vallismortis and its UV-vis spectrophotometric determination(ELSEVIER SCI LTD, 2017) Ozdemir, Sadin; Oduncu, M. Kadir; Kilinc, Ersin; Soylak, MustafaBioaccumulation, resistance and preconcentration of uranium(VI) by thermotolerant Bacillus vallismortis were investigated in details. The minimum inhibition concentration of (MIC) value of U(VI) was found as 85 mg/L and 15 mg/L in liquid and solid medium, respectively. Furthermore, the effect of various U(VI) concentrations on the growth of bacteria and bioaccumulation on B. vallismortis was examined in the liquid culture media. The growth was not significantly affected in the presence of 1.0, 2.5 and 5.0 mg/L U(VI) up to 72 h. The highest bioaccumulation value at 1 mg/L U(VI) concentration was detected at the 72nd hour (10 mg/g metal/dry bacteria), while the maximum bioaccumulation value at 5 mg/L U(VI) concentration was determined at the 48th hour (50 mg metal/dry bacteria). In addition to these, various concentration of U(VI) on alpha-amylase production was studied. The alpha-amylase activities at 0, 1, 2.5 and 5 mg/L U(VI) were found as 3313.2, 3845.2, 3687.1 and 3060.8 U/mg, respectively at 48th. Besides, uranium (VI) ions were preconcentrated with immobilized B. vallismortis onto multiwalled carbon nanotube (MWCNT) and were determined by UV-vis spectrophotometry. The surface macro structure and functionalities of B. vallismortis immobilized onto multiwalled carbon nanotube with and without U(VI) were examined by FT-IR and SEM. The optimum pH and flow rate for the biosorption of U(VI) were 4.0-5.0 and 1.0 mL/min, respectively. The quantitative elution occurred with 5.0 mL of 1 mol/L HCI. The loading capacity of immobilized B. vallismortis was determined as 23.6 mg/g. The certified reference sample was employed for the validation of developed solid phase extraction method. The new validated method was applied to the determination of U(VI) in water samples from Van Lake-Turkey. (C) 2017 Elsevier Ltd.

Seeds(Ankara Univ, Fac Agr, 2014) Hasimi, Nesrin; Tolan, Veysel; Kizil, Suleyman; Kilinc, ErsinIn this research, the essential oil components, antimicrobial and antioxidant properties of anise (Pimpinella anisum L.) and cumin (Cuminum cyminum L.) seed oils were investigated. The essential oil components determined by GC/MS instrument. The antimicrobial activity determined by disc diffusion method against the gram negative bacteria, namely Escherichia coli ATCC 25922, Pseudomonas aeruginosa ATCC 27853, the gram positive bacteria namely Staphylococcus aureus ATCC 25923, Streptococcus pyogenes ATCC19615 and Candida albicans ATCC10231 as the yeast. The antioxidant activities of essential oils were carried out by DPPH free radical scavenging activity method. It was determined that the main components of the anise essential oil were trans-anethole (52.94%) followed by iso-anethole (13.89%), caryophllene oxide (8.55%) and caryophyllene (29.4%); the main components of the cumin essential oil were beta-pinene (15.77%), alpha-terpinene (15:52%), 1-Phenyl-1-butanol (15:13%), cumic aldehyde (12.74%) respectively. Anise essential oil showed weak antimicrobial activity and cumin essential oil showed moderate antimicrobial activity against test microorganisms. Cumin essential oil showed strong antimicrobial activity against C. albicans with 22 +/- 0.9 mm inhibition zone diameter. P. aeruginosa showed resistance to both essential oils. The antioxidant activity of cumin essential oil (75.60%) was observed closer to ascorbic acid (78.75%), higher than BHA (50.45%) and BHT (23.54%). Although anise essential oil exhibited low activity, it has the similar activity with BHT. The scavenging activity of the samples decreasing order was ascorbic acid> cumin >BHA>BHT> anise.Article Citation - WoS: 14Citation - Scopus: 16In situ atom trapping of Bi on W-coated slotted quartz tube flame atomic absorption spectrometry and interference studies(PERGAMON-ELSEVIER SCIENCE LTD, 2013) Kilinc, Ersin; Bakirdere, Sezgin; Aydin, Firat; Ataman, O. YavuzAnalytical performances of metal coated slotted quartz tube flame atomic absorption spectrometry (SQT-FAAS) and slotted quartz tube in situ atom trapping flame atomic absorption spectrometry (SQT-AT-FAAS) systems were evaluated for determination of Bi. Non-volatile elements such as Mo, Zr, W and Ta were tried as coating materials. It was observed that W-coated SQT gave the best sensitivity for the determination of Bi for SQT-FAAS and SQT-AT-FMS. The parameters for W-coated SQT-FAAS and W-coated SQT-AT-FAAS were optimized. Sensitivity of FAAS for Bi was improved as 4.0 fold by W-coated SQT-FAAS while 613 fold enhancement in sensitivity was achieved by W-coated SQT-AT-FAAS using 5.0 min trapping with respect to conventional FAAS. MIBK was selected as organic solvent for the re-atomization of Bi from the trapping surface. Limit of detection values for W-coated SQT-FAAS and W-coated SQT-AT-FAAS was obtained as 0.14 mu g mL(-1) and 0.51 ng mL(-1), respectively. Linear calibration plot was obtained in the range of 2.5-25.0 ng mL(-1) for W-coated SQT-AT-FAAS. Accuracy of the W-coated SQT-AT-FAAS system was checked by analyzing a standard reference material, NIST 1643e. (C) 2013 Elsevier B.V.

Kadir; Kilinc, Ersin; Soylak, MustafaIn this study, uranium(VI) tolerance and bioaccumulation were investigated by using thermo-tolerant Bacillus mojavensis. The level of U(VI) was measured by UV-VIS spectrophotometry. The minimum inhibition concentration (MIC) value of U(VI) was experimented. Bacterial growth was not affected in the presence of 1.0 and 2.5 mg/L U(VI) at 36 h and the growth was partially affected in the presence of 5 mg/L U(VI) at 24 h. What was obtained from this study is that there was diversity in the various periods of the growth phases of metal bioaccumulation capacity, which was shown by B. mojavensis. The maximum bioaccumulation capacities were found to be 12.8, 22.7, and 48.2 mg/g dried bacteria, at 24th hours at concentration of 1.0, 2.5 and 5 mg/L U(VI), respectively. In addition to these, U(VI) has been pre-concentrated on B. mojavensis immobilized MWCNT. Several factors such as pH, flow rate of solution, amount of biosorbent and support materials, eluent type, concentration and volume, the matrix interference effect on retention have been studied, and extraction conditions were optimized. Preconcentration factor was achieved as 60. Under the optimized conditions, the limit of detection (LOD) and quantification (LOQ) were calculated as 0.74 and 2.47 mu g/L. The biosorption capacity of immobilized B. mojavensis was calculated for U(VI) as 25.8 mg/g. The results demonstrated that the immobilized biosorbent column could be reused at least 30 cycles of biosorption and desorption with the higher than 95% recovery. FT-IR and SEM analysis were performed to understand the surface properties of B. mojavensis. (C) 2016 Elsevier Ltd.

Fungal biomass Agaricus bisporus was immobilized to Amberlite XAD-4 as solid-phase sorbent. The critical parameters such as pH of the sample solution, flow rate of the sample, volume of the sample, and the effect of major ions that affect the preconcentration of thorium in this system were evaluated. The optimum pH for the sorption of Th is 6.0, and quantitative elution occurs with 1.0mol L-1HCl. The loading capacity was determined as 0.079mmol g(-1). The optimized method was validated through analysis of the certified reference material of tea leaves (NCS ZC73014) and successfully applied to the determination of Th in a real ore sample with satisfactory results.Article Citation - WoS: 12Citation - Scopus: 16Selective preconcentration of Lanthanum(III) by Coriolus versicolor immobilised on Amberlite XAD-4 and its determination by ICP-OES(TAYLOR & FRANCIS LTD, 2014) Ozdemir, Sadin; Okumus, Veysi; Dundar, Abdurrahman; Celik, Kadir Serdar; Yuksel, Uyan; Kilinc, ErsinCoriolus versicolor, a wood fungus, was immobilised on Amberlite XAD-4 and used as solid-phase biosorbent for preconcentrations of rare earth elements. La(III), Th(IV), U(IV) and Ce(III) were subjected to solid-phase extraction procedure. We observed that La(III) was selectively preconcentrated, while other ions remained in solution at pH 6.0. 5.0mL of 1.0molL(-1) HCl was used to elaute La(III) from column. 250mg of C. versicolor loaded on 1000mg of XAD-4 was optimised as solid-phase matrix. Concentrations of ions in solutions were determined by inductively coupled plasma- optical emission spectrometry (ICP-OES). The calibration plot after preconcentration was linear in the range from 1.0 to 50.0ngmL(-1) for La(III). Limit of detection was found as 0.27ngmL(-1) for La(III) by SPE method. Relative standard deviation was found lower than 6.7% for 1.0ngmL(-1) of La(III) solution (n=10). The sensitivity of ICP-OES was improved by a factor of 46.8. The applicability of the method was validated through the analysis of certified reference samples of tea (NCS ZC-73014) and spinach (NCS ZC-73013).Article Citation - WoS: 20Citation - Scopus: 26Preconcentrations of Ni(II) and Co(II) by using immobilized thermophilic Geobacillus stearothermophilus eSO-20 before ICP-OES determinations(ELSEVIER SCI LTD, 2018) Yalcin, M. Serkan; Ozdemir, Sadin; Kilinc, ErsinThis study deals with the preconcentrations of Ni(II) and Co(II) ions in real samples using the solid phase extraction method (SPE) before their determinations by inductively coupled plasma optical emission spectrometry (ICP-OES). Thermophilic bacterium Geobacillus stearothermophilus SO-20 (Accession number: KJ095002), loaded with Amberlite XAD-4, was utilized as a novel biosorbent. Fourier transform infrared (FT-IR) spectroscopy and scanning electron microscope (SEM) were employed for the investigation of the bacterial surface before and after Ni(II) and Co(II) biosorption. The experimental parameters were examined to find the best conditions. The retained Ni(II) and Co(II) ions on the biosorbent were eluted by using 5.0 ml of 1.0 mol l(-1) HCI as the best eluent. The sorption capacities were found to be 16.8 mg g(-1) for Ni(II) and 21.6 mg g(-1) for Co(II). It was also successfully used for the quantification of Ni(II) and Co(II) in a river water sample, some vegetables and soil.Article Citation - WoS: 43Citation - Scopus: 50gamma-Fe2O3 magnetic nanoparticle functionalized with carboxylated multi walled carbon nanotube for magnetic solid phase extractions and determinations of Sudan dyes and Para Red in food samples(ELSEVIER SCI LTD, 2018) Kilinc, Ersin; Celik, Kadir Serdar; Bilgetekin, HavinHybrid nanostructures composed of gamma-Fe2O3 (maghemite) and carboxylated-multi walled carbon nanotube (cMWCNT) were used for the magnetic solid phase extractions and determination of Sudan I, II, III, IV, Para Red, Sudan Black B and Sudan Red 7B in chili products. High performance liquid chromatography (HPLC) was employed for the measurements. Limit of quantification (LOQ) values were found in the range 0.44-2.82 ng mL(-1) for analytes. The best extraction parameters were determined as pH 8.0, 40 mg of magnetic nanoparticle, 4.0 min of contact time, 0.3 mL desorption by acetonitrile. The samples were dissolved in acetone-dichloromethane-methanol (3: 2: 1, v/v/v) and diluted with acetonitrile-methanol (v/v; 80: 20) before the method was applied. Concentrations of Sudan dyes and Para Red were determined in four samples of chili powder from less than LOQ to 31.21 +/- 1.6 ng g(-1), two samples of chili tomato sauces (lower than LOQ) and two samples of ketchup (lower than LOQ).Article Citation - WoS: 2Citation - Scopus: 2Docetaxel-Loaded, Dipeptide-Functionalized Γ-Fe2o3 Magnetic Nanoparticles: Synthesis, Characterization, and Targeting To Prostate Cancer(Wiley-VCH Verlag GmbH, 2025) Gungoren, Muhammed; Koyuncu, Ismail; Kilinc, Ersin; Baysal, ZubeydeA new delivery system was designed and synthesized to increase the efficiency of docetaxel. For this aim, gamma-Fe2O3 was synthesized in order to give the nanoparticle the ability to be magnetic targeted. It was functionalized with citric acid to prevent clumping and maintain stability. To increase the interaction efficiency between the delivery system and the drug, leucine-glycine dipeptide and an amphiphilic polymer, Pluronic F127, were attached to the nanoparticle. Characterization studies were carried out with XRD, ICP-MS, vibrating sample magnetometer (VSM), TEM, and zeta potential to elucidate the structure of this carrier system. After docetaxel was bound to the synthesized carrier, its therapeutic effect was measured by spectrophotometric and flow cytometric methods (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide [MTT], reactive oxygen species [ROS], and apoptosis). Docetaxel-bound nanoparticles significantly reduced the viability of the tumor cell compared to the healthy cell in a dose-dependent manner, especially at 24 (50.14 +/- 13.25 to 22.32 +/- 5.51 at 100 mu g/mL) h and 48 (41.46 +/- 2.22 to 18.80 +/- 2.81 at 100 mu g/mL) h. The rate of apoptosis and ROS in the negative sample increased from 2.7% to 15.4% and from 9.6% to 74.7%, respectively, as a result of treatment with 15 mu g/mL gamma-Fe2O3/C/LG/F127/Dotx. Thus, it can be said that the synthesized carrier system is a suitable candidate for the improvement of docetaxel transport.Article Citation - WoS: 15Citation - Scopus: 15Investigations of Hg(II) and Pb(II) tolerance, removal and bioaccumulation and their effects on antioxidant enzymes on thermophilic Exiguobacterium profundum(Taylor and Francis Inc., 2019) Akkoyun M.B.; Özdemir S.; Kılınç E.; Birhanlı E.Hg(II) and Pb(II) tolerance, removal, bioaccumulation and effects on antioxidant enzymes of thermophilic Exiguobacterium profundum were investigated. The results indicated that Hg(II) was more toxic than Pb(II) to E. profundum. E. profundum was also more tolerant in solid medium than in liquid medium for Pb(II) and Hg(II). The bacterial growth was not significantly influenced at 1.0 and 2.5 mg/L Pb(II) and Hg(II) for 24 h. The highest Hg(II) and Pb(II) bioaccumulation amounts were determined as 37.56 and 54.35 mg metal/dried bacteria, respectively. Bioaccumulation capacities of the cell membrane of E. profundum forHg(II) and Pb(II)were determined. The different concentrations of Pb(II) and Hg(II) enhanced the SOD and CAT enzymes. In addition, variations of the surface macrostructure and the functionality of E. profundum after the interaction with Hg(II) and Pb(II) were investigated by the scanning electron microscope (SEM) and the Fourier transform infrared spectroscopy (FT-IR), respectively. This investigation obviously showed that thermophilic E. profundum can also be applied for removal and recovery of toxic metals from industrial wastewater. Clearly, a further investigation should be utilized by thermophilic microorganisms. According to antioxidant enyzme activities, E. profundum can be also used as a bioindicator for the detection of toxic metal pollution in natural water samples. © 2019, © 2019 Taylor & Francis Group, LLC.
