A team led by Rice University bioscientist Caroline Ajo-Franklin has discovered how certain bacteria breathe by generating electricity, using a natural process that pushes electrons into their surroundings instead of breathing on oxygen. The findings, published in Cell, could enable new developments in clean energy and industrial biotechnology. By identifying how these bacteria expel electrons externally, the researchers offer a glimpse into a previously hidden strategy of bacterial life. This work, which merges biology with electrochemistry, lays the groundwork for future technologies that harness the unique capabilities of these microscopic organisms. “Our research not only solves a long-standing scientific mystery, but it also points to a new and potentially widespread survival strategy in nature,” said Ajo-Franklin, professor of biosciences, director of the Rice Synthetic Biology Institute and a Cancer Prevention and Research Institute of Texas (CPRIT) Scholar.
