The Gram‐negatice bacterium Acinetobacter calcoaceticus was examined for production of siderophores and iron‐repressible outer membrane proteins following growth in iron‐restricted media. The iron chelator, 2,3‐dihydroxybenzoic acid was identified in the culture supernatant bu 1 H nuclear magnetic resonance (NMR) spectroscopy and mass spectrometry (MS). A group of outer membrane proteins between 80 and 85 kDa were induced under iron restriction.
