German made battery with E. coli as raw material

researchers at the University of Greifswald in Germany found that the working principle of a large tension machine that specializes in eating carbohydrates is a schematic diagram of Enterobacter. At ordinary times, staff should also often check whether the equipment is abnormal and can convert carbohydrates into alcohol, acids, carbonic acid and hydrogen in an oxygen free environment. Using these characteristics, researchers made a battery using this E. coli as raw material in the laboratory

researchers first collected this kind of E. coli through a large number of experiments and used it as a micro "hydrogen manufacturing plant", and then introduced the hydrogen produced by the "manufacturing plant" into a raw material containing oxygen. Hydrogen can release a large number of negative charges when interacting with oxygenated raw materials. In the vessel where this chemical reaction takes place, there is a platinum anode that can connect current. It can make the negative charge released in the reaction flow to the anode to form a current of 150 mA. Polyaniline coating on the surface of platinum anode can delay the corrosion of chemical reactants on the anode. Every 20 minutes, the platinum anode removes the impurities gathered on the anode in the form of voltage surge. The experimental battery made by the above process can work continuously for several hours. Researchers believe that if the process can be further improved, it is expected to be made into a battery using bacteria as raw materials to power small medical appliances
