A comparative study for lipase immobilization onto alginate based composite electrospun nanofibers with effective and enhanced stability
Doğaç, Yasemin İspirli; Deveci, Ilyas; Mercimek, Bedrettin; Teke, Mustafa (Elsevier, 2017)In this study, lipase was successfully immobilized on polyvinyl alcohol/alginate and polyethylene oxide/alginate nanofibers that were prepared by electrospinning. Results showed that nanofibers (especially polyvinyl ... -
Improving of Catalase Stability Properties by Encapsulation in Alginate/Fe3O4 Magnetic Composite Beads for Enzymatic Removal of H2O2
Doğaç, Yasemin İspirli; Çınar, Mürvet; Teke, Mustafa (Taylor & Francis Inc, 2015)The aim of this study was enhancing of stability properties of catalase enzyme by encapsulation in alginate/nanomagnetic beads. Amounts of carrier (10-100 mg) and enzyme concentrations (0.25-1.5 mg/mL) were analyzed to ... -
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 ... -
TiO2 beads and TiO2-chitosan beads for urease immobilization
Doğaç, Yasemin İspirli; Deveci, İlyas; Teke, Mustafa; Mercimek, Bedrettin (Elsevier Science Bv, 2014)The aim of the present study is to synthesize TiO2 beads for urease immobilization. Two different strategies were used to immobilize the urease on TiO2 beads. In the first method (A), urease enzyme was immobilized onto ... -
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 ...
