摘要

A theoretical and experimental systematic study was performed to determine the structural characteristics and functionality that siderophores must have to be used as ecological corrosion inhibitors. Analyses demonstrated that the hydroxamate functional group is the best siderophore that could be used as a corrosion inhibitor of neutral or acidic environments because it would form a smart protective film as good or better than imidazoline.Bacillussp. AS7, isolated from an extreme halo-alkaline terrestrial ecosystem soil sample is producer of desferrioxamine B, a siderophore based on trihydroxamate groups. This siderophore was purified and characterised, its efficiency as a corrosion inhibitor was determined through gravimetric techniques. The obtained siderophore works as an ecological corrosion inhibitor at a minimal concentration of 75 ppm. We demonstrated that the siderophore desferrioxamine B controls efficiently corrosion problems occurring in acid environments characteristic of the oil industry.
