Anthropogenic activities like heavy metal pollution exert the most devastating effect on agriculture. Siderophores are small peptides capable to chelate iron and different heavy metals
thereby reduce metal toxicity. However, very little information is available about their physiology (siderophore types, effect of temperature, pH, toxic metals), and especially of their gene expression patterns. Here, we have carried out a detailed study on siderophore production dynamics along with their gene expression pattern in Enterobacter sp. DRP3. DRP3 was able to produce two different types of siderophores hydroxamate type (19.81 µg ml
