Artists idea of microbial energy generation.
Getting power while cleansing the environment of greenhouse gases should be achievable using germs. In a new publication, microbiologists from Radboud University have actually shown that it is possible to make methane-consuming germs produce power in the lab.
The germs, Candidatus Methanoperedens, utilize methane to grow and naturally take place in fresh water such as ditches and lakes. In the Netherlands, the bacteria mostly flourish in places where the surface and groundwater are polluted with nitrogen, as they need nitrate to break down methane.
In addition, they were likewise curious whether it would be possible to use it to generate power. “In the current biogas installations, methane is produced by microbes and subsequently scorched, which drives a turbine, hence generating power. Less than half of the biogas is converted into power, and this is the optimum possible capability.
A sort of battery
Fellow microbiologists from Nijmegen have previously revealed that it is possible to create power using anammox bacteria that use ammonium throughout the process instead of methane. We grow the germs on one of the electrodes, to which the bacteria donate electrons resulting from the conversion of methane.”
Through this method, the researchers managed to transform 31 percent of the methane into electrical energy, however they target at greater effectiveness. “We will continue focusing on enhancing the system,” Welte says.

Fellow microbiologists from Nijmegen have actually formerly shown that it is possible to generate power utilizing anammox germs that use ammonium during the procedure instead of methane. “The process in these bacteria is essentially the exact same,” says microbiologist Heleen Ouboter. We grow the germs on one of the electrodes, to which the bacteria contribute electrons resulting from the conversion of methane.”
