This siderophore can be used by another methane-oxidizing bacterium from the same community that doesn't produce it, and provides a molecular link between iron speciation in the environment and methane oxidation

We applied InverSIP to a methane-oxidizing bacterial community to identify an iron-chelating secondary metabolite (siderophore) used by methane-oxidizing bacteria to acquire insoluble ferric iron from their environment

We combined stable isotope probing with the inverse labeling method we have been using to link biosynthetic genes to their products in a method we call InverSIP
