ANTAGONISTIC ACTIVITY OF SIDEROPHORES PRODUCED BY PSEUDOMONAS STUTZERI (EGB3) ISOLATED FROM THE GUT OF EISENIA FOETIDAN.D. PRASANNA, K.VIJAYALAKSHMI, G. REVATHI, K. PAVAN JYOTSANA, S.K.SHAHEEN AND P. DEVIKA
Pseudomonas stutzeri was isolated from earthworm (Eisenia foetida) gut found to produce extracelluar siderophores when grown in succinic acid medium under iron deficiency. The siderophores were found to be pyochelin type. These siderophores were antagonistic to plant pathogenic fungi like Fusarium oxysporum, F.solani, F.moniliformae, F.udum, Macrophomena phaseolina, Rhizoctonia solani, Colletotrichum capsicii, Aspergillus flavus and A.niger.
