Magnitude and mechanism of siderophore-mediated competition in bacterial interactions

Vibrio fischerisiderophore production drives competitive exclusion during dual‐species growth

“…Success in inhabiting heterogeneous and/or nutrient-poor marine environments often relies on exploitation of transient microscale nutrient "hot spots" that are associated with detritus, marine snow particles, and marine phytoplankton and zooplankton (reviewed by Stocker and Seymour, 2012). In such environments, key limiting nutritional resources specify the In environments harboring multi-species bacterial communities, siderophores are known to play roles in competition for iron (Weaver and Kolter, 2004;Schiessl et al, 2017;Bruce et al, 2017). Siderophore production enables iron capture and use for the producer while simultaneously denying competitors access to an essential nutrient.…”
