Methane-producing microbes solve one of biology's most energy-demanding challenges: converting carbon dioxide into methane by using an energy-boosting trick called electron bifurcation. Now Researchers at the Max Planck Institute of Biophysics and the Max Planck Institute for Terrestrial Microbiology discovered that different microorganisms link these two reactions in different ways. The findings open up a new understanding of the diversity of molecular architectures that allow methanogens to thrive in different environments.
