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 ... -
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. ... -
Purification and characterization of an alkaline pectin lyase produced by a newly isolated Brevibacillus borstelensis (P35) and its applications in fruit juice and oil extraction
Demir, Nazan; Nadaroğlu, Hayrunnisa; Demir, Yaşar; Işık, Ceyhun; Taşkın, Esen; Adıgüzel, Ahmet; Güllüce, Medine (Springer, 2014)An alkaline pectin lyase (PNL) (EC 4.2.2.10) secreted by Brevibacillus borstelensis P35 (GenBank Number: FJ417406) was purified using ammonium sulfate fractionation, anion exchange chromatography on DEAE-cellulose and gel ... -
Synthesis and characterization of electrospun PVA/Zn2+ metal composite nanofibers for lipase immobilization with effective thermal, pH stabilities and reusability
Işık, Ceyhun; Arabacı, Gökmen; Dogaç, Yasemin İspirli; Deveci, İlyas; Teke, Mustafa (Elsevier Science Bv, 2019)Polyvinyl alcohol (PVA)/Zn2+ electrospun nanofibers that were a kind of polymer/ionic metal composite was successfully embedded in the hybrid fibers for the first time in the literature, due to chemical interactions between ...
