✦ Synopsis

Oxygen utilization, as correlated with the initiation of electrical energy output, has been investigated for systems consisting of E. coli with various substrates, such as glucose, gluconic acid, pyruvate and formate. It was shown that the presence of oxygen in the anolyte serves as an apparent poison in that a current is not produced until the oxygen is completely removed from the system by the micro-organism.

Further, in the absence of oxygen, the system will produce a current more rapidly, indicating again the deterrent effect of oxygen on the production of electrical energy.

La presence d'oxygene dans l'anolyte joue Ie role de poison, car aucun courant ne se manifeste avant consommation complete par le micro-organisme. En absence d'oxygene, le systeme produit un courant plus rapidement.
