Prorocentrin, a putative iron transport compound, has been extracted from the filtrates of Prorocentrum minimum cultures by XAD-2 resin. Production of prorocentrin can be stimulated by culturing Prorocentrum minimum under conditions of iron deficiency. The iron(III) complex of prorocentrin has an ultraviolet-visible absorption spectrum typical of hydroxamate siderophores.
