1973 C. E. Lankford in CRC Crit. Rev. Microbiol. 2 290/2 In consideration of possible existence of functional ferrous-iron chelating compounds in the microbial world [etc.],..the term siderochrome could become nondescriptive of functionally related compounds of microbial origin. A term such as siderophore might be more appropriate.
