Nijmegen, City in the Netherlands

Methane-consuming bacteria can generate power in the lab, according to recent research by scientists of Radboud University.Generating power while purifying the environment of greenhouse gases should be achievable using bacteria.The study was published in the journal. 'Frontiers in Microbiology.The bacteria, Candidatus Methanoperedens, used methane to grow and naturally occur in freshwaters such as ditches and lakes.In the Netherlands, the bacteria mostly thrive in locations where the surface and groundwater are contaminated with nitrogen, as they require nitrate to break down methane.The researchers initially wanted to know more about the conversion processes occurring in the microorganism. In addition, they were also curious whether it would be possible to use it to generate power."This could be very useful for the energy sector", said microbiologist and author Cornelia Welte."In the current biogas installations, methane is produced by microorganisms and subsequently burnt, which drives a turbine, thus generating power. Less than half of the biogas is converted into power, and this is the maximum achievable capacity. We want to evaluate whether we can do better-using microorganisms," she added.Fellow microbiologists from Nijmegen have previously shown that it is possible to generate power using anammox bacteria that use ammonium during the process instead of methane."The process in these bacteria is basically the same", said microbiologist Heleen Ouboter."We create a kind of battery with two terminals, where one of these is a biological terminal and the other one is a chemical terminal. We grow the bacteria on one of the electrodes, to which the bacteria donate electrons resulting from the conversion of methane," she added.Through this approach, the researchers managed to convert 31 per cent of the methane into electricity, but they aim at higher efficiencies. "We will continue focusing on improving the system", Welte concluded.( With inputs from ANI )Disclaimer: This post has been auto-published from an agency feed without any modifications to the text and has not been reviewed by an editor
