The purpose of this paper is to bring more evidence of real participation by the microorganisms in the oxygen-glucose interaction at the black platinum electrodes. From the information obtained it can be concluded that the active participation of the biological agent is achieved by changing the environment near the bioelectrode. The respiratory activity and its incidence on the electrode response were verified when cells were suspended in the bioanode without substrate. In this case no oxygen consumption was observed and no current increase was achieved. Although the catalytic activity of the black platinum electrodes is evident, the active participation of the microorganisms by means of a suitable modification of the environment (i.e., oxygen depletion) increases the electrode response. 13 refs.
