(A) Current production by D. propionicus when pyruvate (2.42 mM) was provided as the electron donor, and a poised electrode (+0.52 V in reference to a standard H2 electrode) served as the electron acceptor. (B) Number of electrons available from the incomplete oxidation of pyruvate that were transferred to the electrode surface. The results are the means of triplicate incubations.
