Microbes often produce molecules (termed siderophores) that bind iron and then are taken up using specific receptors for iron acquisition. Here, the authors show that a compound produced by Bacillus subtilis plays a more complex role, by modulating iron availability and conferring protection against oxidative stress during inter-species competition.
