Abstract
Mediated bioelectrocatalysis based on microbial whole cells are described. Microbial whole cells immobilized on electrodes work as biocatalysts in the electrolytic oxidation or reduction of substrates in the presence of electron transfer mediators between the electrodes and the cells. The catalytic current reflects the characteristics of the microbial cells, such as the membrane permeability, the enzyme reaction rate in the cells. The kinetic features of the bioelectrocatalysis are discussed on the basis of the theory of biocatalyst electrode. Their application to biosensor and bioreactor are also mentioned.
