Robust growth is restored by the addition of iron to the medium implying that this bacterium could be outcompeted by the presence of another organism that produces a high-affinity siderophore He found that in intertidal zones in Scotland, Balanus barnacles were always found closest to the shore, while Chthamalus barnacles grew further up the rocks.
