(A) Current densities of G. sulfurreducens in MECs fed acetate (Ac) or lactate (Lac) at an EAP of 0.7 V. Batch cycles were operated in triplicate in the order shown, with dotted lines representing times of replacement of medium. (B) Current densities of G. sulfurreducens and S. oneidensis in MECs fed lactate during an initial batch cycle at an EAP of 0.7 V. Both cultures were operated in triplicate.
