Abstract
Cellobiose dehydrogenase from Phanerochaete chrysosporium produces H2O 2 by electron transfer between cellobiose and O-2 with a lower yield t han the 1:1:1 molar ratio displayed by Aspergillus niger. glucose oxid ase in the similar reaction between glucose and O-2. The discrepancy c ould best be explained if both a Fenton's reaction and the spontaneous reactivity of the oxygen species formed were taken into account.
