Biofertilizer can be defined as biological products containing living microorganisms that, when applied to seed, plant surfaces, or soil, promote growth by several mechanisms such as increasing the supply of nutrients, increasing root biomass or root area and increasing nutrient uptake capacity of the plant (Vessey, 2003).

Bacteria release low-molecular-weight iron chelators known as “siderophores,” which have high affinity for Fe 3+, bind firmly to it, and are taken up by bacteria. Fe 3+ is converted to Fe 2+ inside the bacterial membrane, and Fe 2+ is discharged into the cell via a gated channel that connects the bacteria’s inner and outer membranes.
