The latest issue of the British “Nature” magazine published a report that marine sediment bacteria in the sediments of the metal will make use of mineral composition, the formation of nanometer-scale, “wire” as a biochemical reaction caused by bacteria conduction current occurs, As a result, bacteria and sediments formed around a natural battery.
Institutions such as the University of Aarhus, Denmark, the researchers report that the upper and lower marine sediment bacteria are present, bacteria will be more contact with the upper part of the water of oxygen, while the lower contact with the bacteria in the sediment organic matter, so they gradually formed a division of labor, the upper part of bacteria responsible for “breathing”, that is, oxidation reaction, while the lower part of bacteria responsible for “eat”, that is, decomposition of organic matter. This process requires electronic spread from the lower part of the upper part.
Nelson said the researchers, in order to achieve this electronic transmission, the bacteria will use some sort of its own composition, removal of metals in sediments around mineral composition, and form an orderly arrangement, to form the final nano-conductive “wires.” As nanotechnology “wire” the existence of bacteria and biochemical reaction can be an endless stream of conduction electrons, and thus generate electricity.
According to reports, although this current is very weak, but if the use of network equipment will be large areas of seabed currents collected, or get some practical use, for example, for floating in the sea on the long-term power monitoring equipment.
