Escherichia coli has at least five independent transport systems, one of which is the low affinity pathway described above. In addition, it synthesizes enterobactin as a siderophore it can take up the iron(III) complex of ferrichrome, a siderophore synthesized by certain fungi there is a citrate-induced system, and a less common process involving aerobactin.
