Azotobacter vinelandii stimulated the growth of Agrobacterium tumefaciens H2, H23, H24, H27, and ATCC 15955 on media containing insoluble iron sources. The Azotobacter vinelandii siderophores appeared to promote Agrobacterium tumefaciens growth by solubilizing mineral iron, and the ferrisiderophores so formed then acted as iron sources for Agrobacterium tumefaciens. Agrobactin, the Agrobacterium siderophore, appeared to be inefficient in solubilizing mineral iron directly.
固氮菌能刺激含有不溶性铁源的培养基中根瘤农杆菌 H2、H23、H24、H27 和 ATCC15955 的生长。固氮菌的铁载体似乎通过溶解矿物铁来促进根瘤农杆菌的生长，然后形成的高铁载体充当根瘤农杆菌的铁源。农杆菌的铁载体农杆菌素似乎不能直接有效地溶解矿物铁。
