Abstract
Siderophores are small molecules that can easily bind to ferric iron. As a chelating agent, they transport iron molecules inside the bacterial cell for various biochemical reaction. At present study, characterization of few siderophores producing bacteria from the soil samples collected from Salem district, Tamil Nadu. The siderophores production was assayed qualitatively and quantitatively through Chrome Azural S and the results showed positive for the strains PS01 and PS02 that grown in succinate medium. In pot culture studies Brassica nigra. L Sesamum indicum. L showed significantly increasing in the root length, shoot length, fresh weight, dry weight and total chlorophyll and carotenoids significantly increased in treated plant The antagonist activity of the siderophore producing Pseudomonas spp against fungal pathogen Fusarium oxysporum. This result showed that Pseudomonas spp is a good producer of siderophore which can be beneficial for its antagonistic activity towards fungal pathogen and increasing the Oil yielding crops.
