Siderophores are low molecular weight secondary metabolites produced by microbes under iron deficiency, to supply iron to the organism. In the rhizosphere crops associated with siderophore-producing microbes may obtain iron through microbially-produced siderophores. There are different classes of siderophores such as hydroxamate, catecholate and mixed ligand siderophores. Under laboratory conditions, these siderophores can be produced in liquid and/or solid media. Subsequently, they can be detected and identified by different methods. This paper describes the production and detection of different siderophores in microorganisms and their interaction with metals such as Fe, Ni, Cd, Cu and Zn. The application of siderophore-producing microbes or siderophore-containing microbial preparations for improving plant growth and enhancing metal remediation of polluted environments is also discussed.
