The solution to the energy problem of mankind may come from an unexpected side, bacteria of the genus Rhodopseudomonas palustris, which can absorb electrons from inorganic substances, such as metal oxides, for example, rust, can help. Scientists from Washington University have identified microorganisms that obtain electrons from inorganic compounds. According to the apt expression of the researchers, the bacteria Rhodopseudomonas \The scientific definition of the process is the extracellular absorption of electrons, associated with the binding and retention of carbon dioxide and the biochemical synthesis of organic compounds. Isolated microorganisms are common throughout the planet. The research involved a strain isolated from rusty metal bridge piers located in Massachusetts. The mechanism of the “electron eating” process is identical to the operation of batteries capable of cyclically discharging and recharging. First, the cell accumulates electrical potential, which is then consumed in the process of carbon dioxide utilization. At the same time, the energy for the redox reaction comes from sunlight. Studying the bacteria Rhodopseudomonas palustris will help scientists better understand the work of living cells that use light energy to support various metabolic processes. The use of similar processes can help in solving problems related to energy problems.
