In response to low iron availability in the environment most microorganisms synthesize iron chelators, called siderophores. Bacteria and fungi produce a broad range of structurally diverse siderophores, all of which show a very high affinity for ferric ions. This book presents an up-to-date overview of the chemistry, biology and biotechnology of these iron chelators. Coverage ranges from an introductory chapter to siderotyping to applications in human and plant health.
