The estimation of perfomanсe of exogenous redox mediators in the bioelectrochemical system glucose–Escherichia coli cells-mediator

The performance of several redox mediators (methylene blue, neutral red. and gallocyanine) in the bioelectrochemical system glucosc- Escherichia coli cells was estimated by means of the rotating disk electrode technique. The diffusion coefficients of the mediators under study were evaluated. Methylene blue and gallocyanine arc shown to be effective reversible electron carriers for the Escherichia coli-based bioanode.
