This paper presents some functional differences as well as similarities observed when comparing the newly discovered cellobiose dehydrogenase (CDH) from Trametes Villosa (T.V.) with the well-characterized one from Phanerochaete chrysosporium (P.c.). The enzymes were physically adsorbed on spectrographic graphite electrodes placed in an amperometric flow through cell connected to a flow system. In the case of T.V.-CDH-modified graphite electrodes,

Flow amperometric and voltammetric investigations were conducted for elucidating and understanding the relation between the various electron transfer processes occurring in cellobiose dehydrogenase (CDH) bound to an electrode surface. Substrate inhibition caused by cellobiose was proven to act in competition with the electron transfer to a two-electron acceptor and under a partial inhibition mechanism for the internal electron transfer process. The

The present paper describes the principle and characteristics of a biosensor for lactose based on a third-generation design involving cellobiose dehydrogenase. As resulted from a previous comparative study (submitted manuscript), the novelty of this lactose biosensor is based on highly efficient direct electron transfer between two newly discovered cellobiose dehydrogenases (CDH), from the white rot fungi Trametes villosa and Phanerochaete sordida,

A cellobiose dehydrogenase (CDH)-modified graphite electrode was designed for amperometric detection of catecholamines in the flow injection mode, by their recycling between the graphite electrode (+300 mV vs. Ag|AgCl) and the reduced FAD cofactor of adsorbed CDH, resulting in an amplified response signal. The high efficiency of the enzyme-catecholamine reaction leads to a detection limit below 1 nM and a sensitivity of 15.8 A M-1 cm-2 (1150 nA/µM)

A new amperometric biosensor based on cellobiose dehydrogenase (CDH) was created for the detection of ortho and para-diphenolic compounds. The developed electrode efficiently discriminates between diphenolic and monophenolic compounds. The analyte, a diphenolic compound, is oxidised on the surface of a graphite electrode at an applied potential of +300 mV vs. Ag/AgCl. The diphenol is then regenerated by the adsorbed CDH in the presence of cellobiose,
