Anew biosensor based on mushroom Agaricus bisporus tissue homogenate was developed for voltammetric determination of ethanol. Mushroom Agaricus bisporus was homogenated and immobilized onto the glassy carbon electrode via gelatine and cross-linked by glutaraldehyde to construct an electrochemical tissue homogenate based biosensor system. The homogenate contains alcohol oxidase E.C 1.1.3.13 enzyme and it catalysis the degredation of ethanol to acetaldehyde and hydrogen peroxide. Assay principle of the biosensor based on the detection of reduction peaks of oxygen by using cyclic voltammetry at potentials between 0.0 and +0.7 V. To obtain a standard graphe for ethanol differential pulse DP method was used at potentials between +0.1 and +0.4 V. The electrode response depends linearly on ethahol concentration between 1.0 and 10.0 mM. Phosphate buffer pH 7.0, 50 mM and 30°C were obtained as the optimum conditions. In characterization studies of the biosensor some parameters such as; repeatability, substrate specificity, interference effects of some substances on the biosensor response were investigated. Finally, the proposed system was applied to ethanol detection in different wine and beer samples.

Mantar Agaricus bisporus Doku Homojenati Temelli Biyosensör Kullanarak Etanolün Voltametrik Tayini

Öz

Bu çalışmada etanolün tayini için mantar Agaricus bisporus doku homojenatı temelli yeni bir biosensor geliştirildi. Mantar Agaricus bisporus homojenize edildi ve elektrokimyasal doku homojenatı temelli bir biyosensör sistemi geliştirmek için camsı karbon elektrot üzerinde jelatin ile immobilize edilip glutaraldehit ile çapraz bağlandı. Homojenat alkol oksidaz enzimi EC 1.1.3.13 içerir ve bu enzim etanolün hidrojen peroksit ve asetaldehite yıkımını katalizler. Biosensörün ölçüm prensibi 0.0 ve +0.7 V potansiyel aralığında döngüsel voltammetri kullanılarak oksijenin indirgenme pikinin belirlenmesine dayanmaktadır. Etanol için standart grafik eldesinde +0.1 ve +0.4 V potansiyel aralığında diferansiyel puls DP metodu kullanıldı. Elektrodun cevabı 1.0 ile 10.0 mM etanol konsantrasyonu aralığında doğrusallık gösterdi. Optimum koşullar olarak pH 7.0 50 mM fosfat tamponu ve 30oC elde edildi. Biyosensörün karakterizasyonu çalışmalarında tekrarlanabilirlik, substrat spesifikliği ve bazı maddelerin biyosensör cevabı üzerine girişim etkileri gibi birtakım parametreler incelendi. Son olarak, geliştirilen sistem, farklı bira ve şarap örneklerinde etanol tayinine uygulandı
