Evaluation of Biological Coating Additives to Reduce Biocorrosion of Steel

In Minnesota (USA), where this study was conducted, biocorrosion severely affects the maritime transportation industry. Here, we investigated the anticorrosion activity of a variety of chemical (magnesium peroxide), biological (surfactin, capsaicin, and gramicidin), and enzymatic (a quorum quenching lactonase) bioactive coating additives. 16Ss rDNA sequencing analysis revealed that the decrease in corrosion wasis associated with a change in the composition of the microbial community at the surface of the steel.
