Siderophore production by the magnetic bacterium Magnetospirillum magneticum AMB-1 is elicited by sufficient iron rather than by iron starvation. In order to clarify this unusual pattern, siderophore production was monitored in parallel to iron assimilation using the chrome azurol sulfonate assay and the ferrozine method respectively. Iron concentration lowered approximately five times less than its initial concentration only within 4 h post-inoculation, rendering the medium iron deficient. A concentration of at least 6 μM Fe3+ is required to initiate siderophore production. The propensity of M. magneticum AMB-1 for the assimilation of large amounts of iron accounts for the rapid depletion of iron in the medium, thereby triggering siderophore excretion. M. magneticum AMB-1 produces both hydroxamate and catechol siderophores.
