Based on the development of bioelectrocalorimetry, allowing the first measurements of heat production of electroactive microorganisms, the microbial electrochemical Peltier effect was discovered. This effect represents an entropic barrier at the interface of an electroactive microorganism and an insoluble electron acceptor during extracellular electron transfer. As for Geobacteraceae based anodes an investment of energy for overcoming this barrier is required, the microbial energy gain is lowered.
