Bacteria of seabed sediments can

In a report published in the latest issue of Nature's British journal, scientists said that bacteria in the ocean floor sediment could take advantage of metallic minerals in sediments, forming 'nets'. nano-electricity and generates electric current due to the biochemical reaction of bacteria.

According to a report by scientists at Aarhus University in Denmark, the upper and lower parts of the seabed sediments exist bacteria, the upper part will be more exposed to oxygen in the water, while micro The lower part of the bacteria is more exposed to organic matter in sediment.

Therefore, they gradually form the assignment, the upper part is responsible for 'respiration', ie the oxidation reaction; The lower part of the bacterium is responsible for 'digestion', ie, decomposing organic matter. This process requires an electronic device to transfer from the bottom to the upper part.

In order to carry out the electron transfer, the bacterium will take advantage of a certain component of itself to transport the metal components in the sediment and arrange it in an order, eventually forming, says Nelson. Nano 'grid' can conduct electricity, thereby producing electric current.

Although this current is very weak, however, if taking advantage of the network model device, the current will be collected in a large area and can be applied in some practical cases such as long-term power supply. for marine surveillance equipment.
