Abstract

Pseudomonas stutzeri, an Earthworm (Eisenia foetida) gut bacteria produces extracelluar siderophores when grown in succinic acid medium under iron deficiency. The siderophores were found to be pyochelin type. These siderophores were antagonistic to fungal pathogens like Alternaria alternata, Fusarium oxysporum, F.solani, F.moniliformae, F.udum, Macrophomena phaseolina, Rhizoctonia solani, Colletotrichum capsicii, Aspergillus flavus and A.niger.
