Biosynthesis of silver nanoparticles using chitosan immobilized Bacillus cereus: nanocatalytic studies
Gupta, Vinod Kumar; Atar, Necip; Yola, Mehmet Lütfi; Darcan, Cihan; İdil, Önder; Üstündağ, Zafer (Elsevier, 2013)In this paper, the biosynthesis study of silver nanoparticles (AgNPs) using chitosan immobilized on the Bacillus cereus (Bc-C) was performed via bioreduction without any reducing agent. Transmission electron microscopy ... -
E. coli’nin Fotooksidatif Stres Altındaki Yaşamına pH’ın Etkisi, Bazı Oksidatif Stres Genlerinin Rolünün Belirlenmesi
Giriş: Fotooksidatif stres ışığa duyarlı moleküllerin ışığa maruz kaldıkları zaman radikal üretmeleri ile gerçekleşmektedir. Oluşan radikaller hücrelerde her türlü moleküle saldırarak hasar verir. Proteinler, lipitler, ... -
The Effect of Antioxidants and pH on Photooxidative Stress with Methylene Blue of E. coli, S. aureus and C. albicans
İdil, Önder; Darcan, Cihan (Eskişehir Teknik Üniversitesi, 2021)In this study, the effect of photooxidative stress on different microorganism groups (Gram positive, Gram negative and Eukaryote) and the role of pH and antioxidants on this effect were investigated. The study was performed ... -
The effect of UV-A and various visible light wavelengths radiations on expression level of Escherichia coli oxidative enzymes in seawater
İdil, Önder; Darcan, Cihan; Özen, Tevfik; Özkanca, Reşit (Kowsar Publishing, 2013)Background: Light and photosensitizers affectthe survival of bacteria in natural environments. Also light and photosensitizers are used for disinfection of materials such as blood, blood products, and water. Objectives: ... -
Escherichia coli’de OmpC ve OmpF Dış Membran Porin Proteinlerinin Farklı Metal Stresindeki Rollerinin Belirlenmesi
Darcan, Cihan; Çetin, Gülçin; Kaygusuz, Özge; İdil, Önder (2015)Bakteriler doğada çok çeşitli streslere maruz kalmaktadırlar. Bu streslerden bir tanesi de metal stresidir. Metaller organizmalar için gerekli oldukları kadar aynı zamanda da zararlıdırlar. Örneğin Ca, Co, Cr, Cu, Fe, Mg, ... -
Investigation of the Role of cyaA/crp Genes of Escherichia coli in Metal Stress
Çetin Kılıçaslan, Gülçin; Kaygusuz, Özge; İdil, Önder; Darcan, Cihan (Adıyaman Üniversitesi, 2021)Adenosine 3 ′, 5′-monophosphate (cAMP) is an important signaling molecule. CRP, the receptor protein of cAMP, acts as the 'main' regulator for transcription factors. The CRP-cAMP complex directly controls at least 500 ... -
The role of oxidative stress genes and effect of pH on methylene blue sensitized photooxidation of Escherichia coli
İdil, Önder; Macit, İkbal; Kaygusuz, Özge; Darcan, Cihan (Akadémiai Kiadó, 2016)In this study, the survival time of wild type E. coli W3110 and 11 mutants was analysed with a plate count method in methylene blue added or control groups under daylight fluoroscence illumination (4950 lux) at different ...
