Produce electricity from milk



A young Romanian-born chemist, Leonard STOICA currently residing position at the Ruhr University in Bochum in Germany, have shown that it is possible to produce an electric current from milk!

He says that it is possible to produce such a power from milk in presence of lactose (with a concentration of about 5%) and dissolved oxygen, which is already present, and two graphite electrodes . According to a recent publication of the team from the University of the Ruhr in the journal Fuel Cells journal, a very detailed examination of changes in the electrode surface clearly shows that there was an electric current between them.

Even if the current generated in this case was only a few tens of microamperes, optimal for a potential of 250 mV, the initial study results that could in future be used in new applications in biotechnology and medicine.

The burgeoning field of biopiles (or biofuel cells) has the full know-how developed in the technology of biosensors. The keys of electricity from milk are among others in progress on the biochemical characterization of new redox enzymes, strategies for building complex structures between redox enzymes and polymers as well as to connect more effectively enzymes on the surface of electrodes.

The previous studies by Leonard STOICA was probably a very important factor in this team. For example STOICA studied in depth about the celobiose dehydrogenase, a redox enzyme that plays an important role in the anode in the experiment.
