title: [Activation, by various aldoses, of dichlorophenol-indophenol reduction by endogenous constituents of a preparation of glucose dehydrogenase from Pseudomonas fluorescens].
abstract: Dichlorophenol-indophenol is reduced neither by D-glucose nor by the endogenous components of a particulate purified glucose-dehydrogenase from Pseudomonas fluorescens, when these two classes of compounds acts individually. In contrast, the dye is quickly reduced by the endogenous components when the reaction occurs in the presence of glucose, without a direct participation of glucose in the reduction. In this effect D-glucose can be replaced by D-mannose, D-galactose or D-xylose, but not by D-fructose.
