This study investigated the adsorption behaviour of two cationic dyes, methylene blue (MB) and malachite green (MG) onto Pleurotus ostreatus, Armillaria tabescens, and Morchella conica mushrooms. The effects of contact time, initial dye concentration, and solution pH (3-11) were also determined. The adsorption on all mushrooms attained equilibrium within 120 min for both MB and MG. To evaluate the experimental kinetics data, the pseudo-first-order, pseudo-second-order, and intraparticle diffusion kinetics equations were utilised. The pseudo-first-order kinetic model demonstrated a good fit with all adsorption kinetics. The Langmuir and Freundlich isotherm models were used to analyse the mechanism of the adsorption isotherm. The adsorption equilibrium isotherm was in a good agreement with the Freundlich model. Thermodynamic parameters such as ΔH enthalpy variation, ΔS entropy variation, and ΔG free Gibbs energy variation were calculated at 303-323 K. The results suggested that the Pleurotus ostreatus mushroom was the most suitable adsorbent for both cationic dyes’ removal.

(Ankara University, 2014) Haşimi, N.; Tolan, Veysel; Tolan, V.; Kizil, S.; Kilinç, E.; 09.03. Department of Nutrition and Dietetics/ Beslenme ve Diyetetik Bölümü; 9. Faculty of Health Sciences / Sağlık Bilimleri Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
In 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 β-pinene (15.77%), α-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. © Ankara Üniversitesi Ziraat Fakültesi.

Introduction. Fighting against cancer and antibiotic resistance are important challenges of healthcare systems, and developing new treatment methods has become the most concentrated area of researchers. Method and Materials. Green synthesis, characterization, and some biological activities of gold nanomaterials (AuNPs) obtained with Gundelia tournefortii (kenger) leaf extract were investigated in this study. Fourier scanning electron microscope, UV-visible spectrophotometer, Fourier transform ınfrared spectroscopy, energy-dispersive X-ray spectrophotometer, X-ray diffraction diffractometer, transmission electron microscope, and Zetasizer instrument data were used to elucidate the structures of nanoparticles. Results. The maximum surface plasmon resonance was observed at 532.15 nm after 1 hour. With the powder XRD model, the mean cubic crystallite size was determined as 23.53 nm. It was observed that the shapes of the obtained AuNPs were spherical, and the dimensions were 5-40 nm and hexagonal. Surface charges (-27 mV) and average size (365.3 nm) of gold nanoparticles were measured with a zeta analyzer. Conclusion. The suppressive effects of AuNPs on the growth of pathogenic microorganisms and healthy and cancer cell lines were determined using the MIC and MTT methods, respectively.

Investigation of Antimicrobial and Cytotoxic Properties and Specification of Silver Nanoparticles (AgNPs) Derived From Cicer arietinum L. Green Leaf Extract
(FRONTIERS, 2022) Keskin, Cumali; Hatipoğlu, Abdulkerim; Baran, Ayşe; Baran, Mehmet Fırat; 21.02. Department of Medical Services and Techniques / Tıbbi Hizmetler ve Teknikleri Bölümü; 09.03.

Using biological materials to synthesize metallic nanoparticles has become a frequently preferred method by researchers. This synthesis method is both fast and inexpensive. In this study, an aqueous extract obtained from chickpea (Cicer arietinum L.) (CA) leaves was used in order to synthesize silver nanoparticles (AgNPs). For specification of the synthesized AgNPs, UV-vis spectrophotometer, Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction analysis (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM), electron dispersive X-ray (EDX), and zeta potential (ZP) analyses data were used. Biologically synthesized AgNPs demonstrated a maximum surface plasmon resonance of 417.47 nm after 3 h. With the powder XRD model, the mean crystallite dimension of nanoparticles was determined as 12.17 mm with a cubic structure. According to the TEM results, the dimensions of the obtained silver nanoparticles were found to be 6.11–9.66 nm. The ZP of the electric charge on the surface of AgNPs was measured as −19.6 mV. The inhibition effect of AgNPs on food pathogen strains and yeast was determined with the minimum inhibition concentration (MIC) method. AgNPs demonstrated highly effective inhibition at low concentrations especially against the growth of B. subtilis (0.0625) and S. aureus (0.125) strains. The cytotoxic effects of silver nanoparticles on cancerous cell lines (CaCo-2, U118, Sk-ov-3) and healthy cell lines (HDF) were revealed. Despite the increase of AgNPs used against cancerous and healthy cell lines, no significant decrease in the percentage of viability was detected.

(Environmental Technology and Innovation, 2020) Yıldırım, Ayfer; Acay, Hilal; Baran, Mehmet Fırat; 21.02. Department of Medical Services and Techniques / Tıbbi Hizmetler ve Teknikleri Bölümü; 09.03.

Adsorption is very economical and environmentally friendly method that is commonly accepted as a promising technique for the removal of heavy metals. In this study a fungal-extract-based (FE-CB) bio-nanosorbent was prepared and used as an efficient biosorbent for the removal of heavy metals, namely Cu(II) and Ni(II), from aqueous solutions. FE-CB was characterized by scanning electron microscope, Brunauer–Emmett–Teller surface area and porosity analyzer, Fourier transform infrared, x-ray diffraction, differential scanning calorimeter, thermalgravimetric analysis and zeta potential. The Brunauer–Emmett–Teller surface area, pore volume and average pore diameter of FE-CB were 7.43 m2/g, 0.060 cm3/g, and 2.82 nm, respectively. The adsorbtion properties of FE-CB onto both Cu(II) and Ni(II) were investigated in terms of biosorbent dosage, temperature, initial concentration of Cu(II) and Ni(II) ions, pH and contact time in the batch experiments. The dependence of the biosorption mechanism on pH was revealed and the optimum pH was determined as 6 for Ni(II) and 5 for Cu(II). The Langmuir and Freundlich isothermal models and the kinetic Pseudo-first-order and Pseudo-second-order kinetic models were used to describe the adsorption performance of FE-CB. The activation energy was calculated by pseudo-second-order rate constants. In addition, thermodynamic parameters, standard Gibbs free energy, standard enthalpy and standard entropy were analyzed using the (Van't Hoff equation). The biosorption process was found to be spontaneous, favorable and endothermic.
