Read moreIn recent years, researchers have tried to capture the electrical current that bacteria generate through their own metabolism. So far, however, the transfer of the current from the bacteria to a receiving electrode has not been efficient at all. Now, they have achieved a slightly more efficient transfer of electrical current.
