nitrogenase and vibrioferrin

Azotobacter vinelandii is a terrestrial diazotroph well studied for its siderophore production capacity and its role as a model nitrogen fixer. In addition to Fe, A. vinelandii siderophores are used for the acquisition of the nitrogenase co-factors Mo and V. However, regulation of siderophore production by Mo- and V-limitation has been difficult to confirm and knowledge of the full suite of siderophores synthesized by this organism has only recently become available. Using this new information, we conducted an extensive study of siderophore production in N
