22 p, 1.2 MB A novel bio-electronic tongue using cellobiose dehydrogenase from different origins to resolve mixtures of various sugars and interfering analytes / Cipri, Andrea (Universitat Autònoma de Barcelona. Grup de Sensors i Biosensors) ; Schulz, Christopher (Lunds universitet. Department of Analytical Chemistry/Biochemistry and Structural Biology) ; Ludwig, Roland (Universität für Bodenkultur Wien. Department of Food Science and Technology) ; Gorton, Loo (Lunds universitet. Department of Analytical Chemistry/Biochemistry and Structural Biology) ; Valle Zafra, Manuel del (Universitat Autònoma de Barcelona. Departament de Química)
A novel application of cellobiose dehydrogenase (CDH) as sensing element for a Bioelectronic Tongue (BioET) system has been tested. In this work CDHs from various fungi, which exhibit different substrate specificities, were used to discriminate between lactose and glucose in presence of the interfering matrix compound Ca²⁺ in various mixtures.
