Bacteria found under the sea that transmit electrons over long distances

Bacteria found under the sea that transmit electrons over long distances

A group of researchers from Denmark and the U.S. have found the key to the strange electrical currents passing through the bottom of the sea. bacteria that live and function as electric cables , a discovery that could change the organic electronics and even the creation of devices which can be implanted in the human body in the future.

And three years ago, scientists discovered underwater electrical currents to those who had not managed to decipher their origin. These bacteria could be key, a remarkable finding biological engineering confirming that each small section of the bacterium contains a bundle of insulated wires leading to an electrical current from one end to the other.

According count Aarhus University researchers began to suspect something was up when they saw the emergence of a type of bacteria multicellular. Bacteria that had always existed when electric currents around. In addition, the scientists found that the currents were interrupted when introduced into the water a thin wire and then took it out, an indication that there was any connection broken.

It was then that became further analysis found that the bacteria, a hundred times thinner than a human hair, containing nanoscale chains surrounded by a membrane. They concluded that whole body functions made virtual electric cable with capabilities similar to those of the electrical cables that we use daily.

The study comes to say that if true, the adaptation of this bacterium gives a clear advantage over other microbes in the ocean. His ability to drive a current that would attract large amounts of energy that are placed through the decomposition of the seabed.

Another feature which is pointing can be maintained in efficient combustion of the free oxygen from the seabed. I would thanks to the formation of a string in which the bacteria are spread in an area rich in oxygen from seawater, would only need a few millimeters. When combustion occurs, there is a transfer of electrons to oxygen food. As happen with ordinary electric wire, any change would lead to a breakage.

In any case, the finding could inspire developments in the field of organic electronics. If the bacteria or something similar could be designed, the researchers point to these biological systems for driving current in advanced electronic devices, becoming possible as prosthetic devices for humans.
