Iron deficiency is one of the main causes of chlorosis in plants, which leads to losses in field
crops quality and yield. The use of synthetic chelates to prevent or correct iron-deficiency is
not satisfactory mainly due to their poor biodegradability. The present work aimed to search
suitable microorganisms to produce alternative, environment-friendly iron-chelating agents
(siderophores). For this purpose, the performance of five bacteria (Azotobacter vinelandii,
Bacillus megaterium, Bacillus subtilis, Pantoea allii and Rhizobium radiobacter) was …
