At the Weil River estuary in Sunderland, England, it was here that the scientists found this mysterious bacterium.
Scientists have discovered bacteria species commonly found in high altitudes in a river in the United Kingdom. The bacteria will hopefully provide new energy for the world. This mysterious bacterium was discovered in the mouth of the Weil River in the Sunderland region of the United Kingdom. Microbial fuel cells made from this bacteria can generate electricity.
The bacterium is called "Bacillus streptococci" and it usually lives at an altitude of 32 kilometers above the ground. The discovery of them in the river may be due to the atmospheric circulation that brought them down. This atmospheric cycle allows water vapor to rise and fall again.
This kind of special bacteria with vitality can be used in microbial fuel cells to convert waste water into electricity and clean water. In the environment of an oxygen-free solution inside this special battery, these bacteria release carbon dioxide, protons, and electrons. Free electrons then constitute the negative electrode, while protons constitute the positive electrode. This will produce electricity.
Grant Burgess, a professor of marine biotechnology at Newcastle University, said that the scientific team separated 75 different species of bacteria from the Weil River and put them one by one in a microbial fuel cell to test their power generation capabilities. Once the best candidate for the bacteria is found, scientists can begin to build a man-made biofilm that will double the capacity of ordinary microbial fuel cells, from 105 watts per cubic metre to 200 watts per cubic metre.
Although this kind of power generation efficiency still appears to be low, it is enough to light up an electric light and bring gospel to those areas of the world that are in desperate need of electricity for lack of electricity and electricity. The use of micro-organisms to generate electricity is not a new concept, but people also use them for waste water and sewer processing. Professor Burgess said: "This method is really interesting. We can actually collect electricity from bacteria that seem to be useless."
