Inverse stable isotope probing–metabolomics (InverSIP) identifies an iron acquisition system in a methane-oxidizing bacterial community

Proceedings of the National Academy of Sciences, Volume 122, Issue 36, September 2025. <br/>SignificanceMethane-oxidizing bacterial communities perform a critical ecosystem function by consuming this potent greenhouse gas, but the molecular mechanisms governing their activity are not well understood. We developed a genomics-guided method for …
