Discover that electron-feeding bacteria can release electrons or create new patterns for life

According to media reports, there are countless kinds of bacteria in the world, but scientists have discovered a kind of bacteria, which is different from any other life on earth. This kind of bacteria mainly uses the purest form of electron energy as food. Breathing also depends on electronics. They are everywhere. You just need to insert an electrode on the ground, input electrons, and they will appear soon. These bacteria are called "food bacteria" by scientists.

Discovering electron-feeding bacteria can release electrons or new patterns for life

There are two types of food-borne bacteria: Shewanella and Geobacterium, which can attract more electrons from rocks and deep-sea mud with a little electro-hydraulic. The shapes and sizes of food-borne bacteria vary, and biologists have found that some food-borne bacteria grow hair-like filaments, like wires, that transport electrons back and forth between cells and their environment. "Microbial nanowires."

The researchers cultured the bacteria on the electrodes of the battery and found that, in essence, the organisms ingested and discharged electricity. The researchers collected some sediments, brought them to the laboratory, and inserted electrodes for culture experiments. They detected the natural voltage of the deposit and then applied a slightly higher voltage and a slightly lower voltage to provide additional electrons and absorb the released electrons. Bacteria in the sediment can "eat" electrons from high voltages, "exhale" electrons to low voltages, and generate electricity.

People may be surprised by the existence of this bacterium, but scientists say that life is originally a flow of electrons, such as eating sugar, taking in excess electrons, breathing oxygen, and then draining excess electrons. Cells break down sugars, and electrons flow through a complex series of chemical reactions that eventually combine with oxygen that lacks electrons. In this process, the cells synthesize adenosine monophosphate (ATP). ATP is a molecule that stores energy in all life.

The researchers said that bacteria should not grow on one electrode and grow between the two electrodes. These bacteria can quickly take electrons from one electrode and release electrons on the other, so they can be used as an energy source. Researchers are interested in this bacterium, a food-borne bacterium that grows between two electrodes, in fact, can sustain its own life forever, without destroying it. This creature only needs very little energy to survive, perhaps representing another life pattern in the solar system. On Earth, food-borne bacteria also have practical uses, such as creating biological machines for cleaning sewers or underground sewage, which can extract the energy they need from the environment.
