Azospirillum lipoferum M was found to produce catechol-type of siderophores under iron-starved conditions. Chemical characterization of siderophores revealed the presence of salicylic acid, 2,3-dihydroxybenzoic acid (DHBA), and 3,5-DHBA conjugated with threonine and lysine. Siderophore production was found to be maximum after 28 h of growth. In addition to their established role in iron transport, the siderophores exhibited antimicrobial activity against various bacterial and fungal isolates.
