Antibiofilm and anti-quorum sensing activities of polyethylene imine coated magnetite and nickel ferrite nanoparticles
Ceylan, Özgür; Tamfu, Alfred Ngenge; İspirli Doğaç, Yasemin; Teke, Mustafa (Springer Science and Business Media Deutschland GmbH, 2020)This study was aimed at synthesizing polyethyleneimine-coated magnetic nanoparticles and evaluating their effect on pathogenic bacteria. Polyethyleneimine-coated magnetite (PEIMnF) and nickel ferrite (PEINF) nanoparticles ... -
beta-cyclodextrin based electrospun nanofibers for arginase immobilization and its application in the production of L-ornithine
Işık, Ceyhun; Teke, Mustafa (SPRINGER, 2022)Electrospinning is the most effective and efficient method for nanofiber production. In this study, polyvinyl alcohol (PVA)/beta-cyclodextrin (beta-CD) and PVA/beta-CD/Mn2+ electrospun nanofibers were synthesized for use ... -
DEVELOPMENT OF A NEW BIOSENSOR FOR DETERMINATION OF CATALASE ACTIVITY
Teke, Mustafa (Taylor & Francis Inc, 2014)Catalase is one of the major antioxidant enzymes that catalyzes the hydrolysis of H2O2. The aim of this study was to suggest a new method for the assay of catalase activity. For this purpose, an amperometric biosensor based ... -
Fabrication of electrospun cellulose-derived nanofiber membranes with enhanced stability properties of arginase
Işık, Ceyhun; Teke, Mustafa (TUBITAK, 2022)In this study, cellulose acetate (CA)/polyvinylpyrrolidone (PVP) and CA/PVP/Mn2+ nanofibers were produced by the electrospinning method, and these cellulose-derived membranes were used as carriers for arginase immobilization ... -
Milk lactose removal by β-galactosidase immobilized on eggshell membrane
Kızıldağ, Selen; Işık, Ceyhun; Teke, Mustafa (Springer Science and Business Media Deutschland GmbH, 2023)Eggshell membrane (ESM) is used in immobilization studies due to its large surface area, non-toxicity and biodegradability. In this study, β-galactosidase was immobilized on ESM using the adsorption and cross-linking method. ... -
A new bioremediation method for removal of wastewater containing oils with high oleic acid composition:Acinetobacter haemolyticuslipase immobilized on eggshell membrane with improved stabilities
Işık, Ceyhun; Saraç, Nurdan; Teke, Mustafa; Uğur, Aysel (Royal Society of Chemistry, 2021)As a result of the increasing demand for edible oils, which are an important part of human nutrition, in recent years, serious environmental problems may arise both during the production and after consumption of these oils. ... -
A selective molecularly imprinted polymer for immobilization of acetylcholinesterase (AChE): an active enzyme targeted and efficient method
Demirci, Gökhan; Doğac, Yasemin İspirli; Teke, Mustafa (Wiley-Blackwell, 2015)In the present study, we immobilized acetylcholinesterase (AChE) enzyme onto acetylcholine removed imprinted polymer and acetylcholine containing polymer. First, the polymers were produced with acetylcholine, substrate of ... -
Synthesis and Characterisation of Biocompatible Polymer-Conjugated Magnetic Beads for Enhancement Stability of Urease
Doğaç, Yasemin İspirli; Teke, Mustafa (Springer, 2016)We reported natural polymer-conjugated magnetic featured urease systems for removal of urea effectively. The optimum temperature (20-60 A degrees C), optimum pH (3.0-10.0), kinetic parameters, thermal stability (4-70 A ... -
Urease immobilized electrospun PVA/chitosan nanofibers with improved stability and reusability characteristics: an application for removal of urea from artificial blood serum
Kutlu, Nur; Doğaç, Yasemin İspirli; Deveci, Ilyas; Teke, Mustafa (Taylor & Francis Inc, 2020)Electrospun polyvinyl alcohol (PVA)/Chitosan nanofibers were successfully prepared and were used as carriers for the first time in urease immobilization. Also, urease immobilized electrospun PVA/Chitosan nanofibers were ...
